Best Free AI Tools for Teachers in 2026

Teaching is one of the most rewarding jobs in the world, but it is also one of the busiest. A teacher does not only teach in the classroom. Before the lesson, a teacher plans. After the lesson, a teacher marks homework, prepares quizzes, writes feedback, talks to parents, and gets ready for the next day. Many teachers work late at night and on weekends just to keep up with all this work.

In 2026, free AI tools can help teachers save time and reduce stress. These tools do not replace a teacher. No AI tool can understand your students the way you do. No AI tool can give a shy student confidence, notice when a child is sad, or celebrate a small win in the classroom. But AI tools can do the repetitive work faster. They can help you write a first draft of a lesson plan, create quiz questions, make a worksheet for different levels, summarise a long text, and organise your ideas.

This guide is written in easy English for beginners. You do not need any technical skills to use these tools. If you can type a question and read the answer, you can use AI in your classroom. We will show you the best free AI tools for teachers in 2026, what each tool is best for, what the free plan offers, and why we like it. We will also show you step-by-step guides for a lesson plan in 10 minutes, a quiz from a topic, and a worksheet for different levels. You will also learn about student privacy and safety, free versus paid plans, common mistakes to avoid, and answers to 17 frequently asked questions.

Check the official website for the current free plan and limits for every tool in this guide, because free plans change from time to time. Always check your school policy before you use a new tool with student data.

What Does AI Do for a Teacher?

AI for teachers means you use artificial intelligence to do the repetitive parts of teaching faster, so you have more time for your students. You type a short instruction, and the AI gives you a first draft — a lesson plan, a set of quiz questions, a worksheet, a parent email, or a simple explanation. You then read it, check the facts, fix what is wrong, and add your own examples and stories.

AI is best for planning, drafting, and checking. It is not a replacement for your judgement. AI does not know your students. It does not know that one student needs simpler text, or that another finishes work very fast. You decide what is good, you adjust it for your real class, and you make the final decision. Used this way, AI can save a busy teacher several hours every week.

Best Free AI Tools for Teachers at a Glance

Free plans change often, so check the official website of each tool for current free limits before you plan your lessons around it.

1. ChatGPT

ChatGPT is the most flexible tool on this list. You can ask it almost anything in normal English, and it will give you a clear answer. It is very good at turning a short idea into a full lesson plan, a list of quiz questions, a parent email, or a simple explanation for students. You can also ask it to rewrite the same text at a different level, for example, "Rewrite this paragraph for Grade 5 students," or "Make this explanation simpler." You can ask it to make a table, a list, a story, a dialogue, or a set of examples.

If you are new to AI, start here, because once you learn how to write good prompts for ChatGPT, you can use the same skill in almost every other AI tool.

A good example prompt is: "You are a helpful teacher. Make a 40-minute lesson plan for Grade 6 about fractions. Include learning objectives, a warm-up activity, main teaching points, three practice activities, and five quiz questions with answers." ChatGPT will give you a full plan in seconds. Then you can edit it for your class.

Key Features:

• Turns a short idea into a full lesson plan, quiz, email, or explanation
• Rewrites the same text at a different level for different students
• Makes tables, lists, stories, dialogues, and examples in seconds
• Good prompts learned here work in almost every other AI tool

Best for: Lesson plans, explanations, worksheets, emails, and almost any writing task

Free plan: ChatGPT offers a free plan. The free plan is enough for many teachers to try AI and use it every day for basic tasks. Check the official website for the current free plan and limits, because the free plan can change.

How to Use ChatGPT Step by Step:

1. Go to chatgpt.com and create a free account.
2. Write a clear prompt with the grade, subject, topic, and time, for example: "Make a 40-minute lesson plan for Grade 6 about fractions."
3. Read the full answer and check the facts, especially for science, maths, and history.
4. Ask ChatGPT to fix anything that is wrong, or to make an easier and a harder version.
5. Copy the result into your own document, add your own examples, and save it for next year.

Watch out for: ChatGPT can make mistakes with facts and numbers. Always read and check its work before you use it in class.

2. Gemini

Gemini is Google's AI assistant, and it works well if your school already uses Google Classroom, Google Docs, Google Slides, or Gmail. You can ask Gemini to summarise a long article, explain a topic, make a table, or draft a lesson outline. It is also useful for research, because it can search for recent information and give you links to check.

Teachers like Gemini because it feels simple and clean, and because it can help inside Google tools. For example, you can use it to draft an email to parents, to make a list of discussion questions from a reading passage, or to turn your notes into a clear handout. It is a strong all-round assistant, just like ChatGPT, and many teachers use both and choose the one that gives a better answer for that task.

Key Features:

• Works well with Google Classroom, Docs, Slides, and Gmail
• Summarises long articles and explains topics in simple words
• Can search for recent information and give links to check
• Drafts parent emails, discussion questions, and handouts

Best for: Teachers who use Google tools, research, summaries, and lesson ideas with Google Docs and Slides

Free plan: Gemini offers a free plan. Check the official website for the current free plan and limits.

How to Use Gemini Step by Step:

1. Go to gemini.google.com and sign in with your Google account.
2. Type your question in normal English, for example: "Summarise this article for Grade 7 students."
3. Paste a long text or a link if you want a summary or questions from it.
4. Ask Gemini to make a table, a list of discussion questions, or a lesson outline.
5. Copy the result into Google Docs or Slides and edit it for your class.

Watch out for: Gemini's answers can be general. Add your own examples and check facts before you teach them.

3. Claude

Claude is known for writing in a clear, natural, and careful way. It is very good when you need to work with a long text, such as a chapter, a long article, or a set of student instructions. You can paste a long text and ask Claude to summarise it, to make questions from it, to simplify it, or to find the main ideas.

Teachers also like Claude for writing feedback, because it can help you write kind, clear, and specific comments for students. If you need to write a rubric, a project guide, or a long worksheet with careful wording, Claude is a great choice. It is also useful when you want the AI to follow your instructions very closely and not add extra information that you did not ask for.

Key Features:

• Very good with long texts: chapters, articles, and student instructions
• Summarises, simplifies, and makes questions from long documents
• Helps write kind, clear, and specific feedback for students
• Follows your instructions closely without adding extra information

4. For feedback, paste a student's work without the student's name and ask for kind, specific comments.
5. Copy the best parts into your own document and adjust the wording for your class.

Watch out for: Never paste student names or personal details into Claude or any public AI tool. Remove names first.

4. Canva Magic Studio

Canva Magic Studio is inside Canva, the popular design tool. It adds AI features that help you make slides, posters, worksheets, flashcards, and classroom decorations much faster. You can type a short description, and Canva will suggest a design, a layout, or a full presentation. You can use Magic Write to draft text for a slide, Magic Design to turn an idea into a poster, and other AI tools to resize, improve, or rewrite your work.

For teachers, the biggest benefit is time. Instead of spending one hour making a presentation, you can make a good first version in 10 minutes and then fix the colours, pictures, and words. Canva for Education also gives teachers extra features for free, so check if your school can apply for it.

Key Features:

• Makes slides, posters, worksheets, flashcards, and classroom displays fast
• Magic Write drafts text and Magic Design turns an idea into a design

Watch out for: Some AI features and premium templates need a paid plan, so check which features are free first.

5. Curipod

Curipod helps you make interactive lessons that students join on their own devices. You type a topic, and Curipod creates slides with polls, open questions, word clouds, drawings, and quizzes. Students answer live, and you can see their answers on your screen.

This is great for shy students, because they can answer without speaking in front of the whole class. It is also great for checking understanding during a lesson, not only at the end. Teachers like Curipod because it makes a normal lesson feel like a game, and because it takes only a few minutes to create a lesson. You can use it for a warm-up, a revision lesson, a discussion, or a full class activity.

6. Diffit

Diffit solves a common classroom problem. In one class, some students read very well, some read at an average level, and some need simpler text. Making three versions of the same worksheet by hand takes a long time. Diffit does it in seconds. You paste a text, a link, or a topic, and Diffit creates a reading passage at the level you choose, plus a summary, key vocabulary, and questions. You can make the same topic easier or harder, so every student can learn the same idea at the right level.

Teachers also use Diffit to make short readings from a YouTube video or a long article. It is one of the best tools for differentiation, which means giving different students work that fits their level.

Key Features:

• Makes the same reading passage at different levels in seconds
• Creates a summary, key vocabulary, and questions with the passage
• Works from a text, a link, a topic, or a YouTube video
• Best tool on this list for differentiation in one class

4. Diffit will create the passage, a summary, vocabulary, and questions.
5. Download the worksheet and check the level before you print it for your class.

Watch out for: Always read the passage yourself. Check that the level is right for your students and that the facts are correct.

7. Brisk Teaching

Brisk Teaching is a Chrome extension that works inside Google Docs, Google Slides, web articles, and YouTube. That means you do not need to open a new website and copy and paste your work. You can open a student's essay in Google Docs, click Brisk, and ask it to give feedback, check for key points, or suggest a grade based on your rubric. You can also open an article and ask Brisk to change its reading level, make questions, or summarise it for your class.

Teachers like Brisk because it saves time where they already work. It is especially useful for English teachers, writing teachers, and any teacher who marks a lot of written work.

Key Features:

• Works inside Google Docs, Slides, articles, and YouTube — no copy and paste
• Gives feedback on student writing and suggests a grade from your rubric

Watch out for: Brisk only works in Chrome with the extension installed. Never paste student names into it without school approval.

8. MagicSchool AI

MagicSchool AI is made only for teachers. It is not a general chatbot. It has ready-made tools for almost every teaching task. You can choose a tool for lesson plans, unit plans, quiz questions, rubrics, IEP suggestions, report card comments, parent emails, behaviour plans, science labs, math word problems, and much more. You just fill in a few boxes, such as grade, subject, and topic, and MagicSchool gives you a result made for teachers.

This is very helpful for new teachers and busy teachers, because you do not need to learn how to write perfect prompts. You just choose the tool and fill in the details. MagicSchool also has a student version with safety controls, so check your school policy before you let students use it.

9. Quizizz AI

Quizizz is already popular for quizzes and games in class, and its AI features make it even faster. You can type a topic, paste a text, or upload a document, and Quizizz AI will create quiz questions for you. You can choose multiple choice, true or false, fill in the blank, and other question types. You can also set the difficulty, the number of questions, and the grade level.

Students can play the quiz live in class or as homework, and you get instant results that show who understood the topic and who needs more help. Teachers like Quizizz because it turns revision into a fun competition, and because the results help you plan your next lesson. It is a great tool for quick checks, end-of-topic tests, and exam revision.

Important change — please read: Quizizz is now called Wayground. The company rebranded in June 2025. If you go to quizizz.com, you will land on Wayground. Your account, your saved quizzes, your classes, and your join codes all still work — only the name and the look changed. The AI quiz features are still there, now under the Wayground name.

Key Features:

• Creates quiz questions from a topic, a text, or a document in seconds
• Multiple choice, true or false, fill in the blank, and other question types

4. Read every question and answer. Check that the correct answer is really correct.
5. Share the quiz live in class or assign it as homework, then look at the results to plan your next lesson.

Watch out for: Always check every question before you use the quiz. A wrong answer in a quiz can confuse students. And do not be confused by the new name — Wayground is Quizizz, just with a new name since June 2025.

10. Khanmigo

Khanmigo is made by Khan Academy, the well-known free learning platform. It is an AI tutor that does not just give students the answer. It asks questions, gives hints, and guides students step by step, like a good teacher. For teachers, Khanmigo can help with lesson planning, making questions, and supporting students who need extra help.

It is especially useful for maths, science, and other subjects where students need to practise and understand each step. Because it comes from Khan Academy, it is designed for education and learning, not just for quick answers. Check if your school has access, because many schools can use it for free or at a low cost.

Key Features:

• AI tutor that guides students step by step instead of giving the answer
• Asks questions and gives hints, like a good teacher
• Helps teachers with lesson planning, questions, and extra support
• Made by Khan Academy, designed for education and learning

11. Twee

Twee is made for English language teachers. It can make reading texts, dialogues, vocabulary exercises, grammar questions, and speaking activities in seconds. You can paste a text or a YouTube link, choose the level, and Twee will make questions, true or false items, gap fills, and discussion questions.

It is very useful for ESL and EFL teachers, because it saves hours of worksheet preparation. It is also useful for any English teacher who wants fresh reading material for a class. Twee understands language levels such as A1, A2, B1, B2, and C1, so you can make work that fits your students exactly. If you teach English, this is one of the most useful tools on the list.

• Makes reading texts, dialogues, vocabulary, grammar, and speaking activities
• Works from a text or a YouTube link, at the level you choose

Watch out for: Check the level carefully. A B1 text is too hard for A1 students, and too easy for B2 students.

12. Eduaide

Eduaide is another tool made only for teachers. It has a large library of tools for lesson planning, assessment, feedback, and classroom management. You can make a lesson plan, a unit plan, a quiz, a rubric, a project outline, or a set of discussion questions. You can also use it to write feedback for students, to make a behaviour plan, or to create a resource for a specific topic.

Teachers like Eduaide because it is organised, simple, and focused on teaching. It also has a feature that helps you generate ideas for different types of learners, so you can plan for visual, auditory, and hands-on learners in the same lesson.

How to Choose the Best Free AI Tool for Teachers

There are many AI tools for teachers. How do you choose the right one? Do not just pick the first tool you see. Think about your biggest problem first.

1. What is your biggest problem? If you spend too much time on lesson plans, start with ChatGPT, MagicSchool AI, or Eduaide. If quizzes take too long, start with Quizizz (Wayground) or Curipod. If your students read at very different levels, start with Diffit. If marking takes too long, start with Brisk Teaching. Pick the tool that solves your biggest problem first.

2. Is the free plan enough for you? Most tools in this guide have a free plan. But free plans are different. Some give you a limited number of lessons or quizzes per month. Some add limits on advanced features. Before you plan your lessons around a tool, check the official website for the current free plan and limits. Free plans change often, so always check the official website.

3. Do you want a general chatbot or a teacher tool? ChatGPT, Gemini, and Claude are general chatbots. They can do almost anything, but you need to write good prompts. MagicSchool AI and Eduaide are made only for teachers. They have ready-made tools, so you just fill in the boxes. If you are new to AI, a teacher tool is easier. If you like writing prompts, a general chatbot gives you more control.

4. Does it work where you already work? If your school uses Google Docs and Google Classroom, Gemini and Brisk Teaching fit well. If you use Canva for slides, Canva Magic Studio fits well. Choose a tool that works with what you already use, so you do not waste time learning a new system.

Start with two or three tools. Learn them well for two weeks. Add a new tool only when you need it.

Step-by-Step Guide: Make a Lesson Plan in 10 Minutes

Follow these steps to make a lesson plan in 10 minutes:

Step 1: Choose your tool. Open ChatGPT, Gemini, Claude, MagicSchool AI, or Eduaide. MagicSchool AI and Eduaide are best for beginners, because they have a ready-made lesson plan tool. ChatGPT is best if you want more control.

Step 2: Write a clear prompt. Copy and change this example: "Make a 45-minute lesson plan for Grade 7 Science about the water cycle. Students are 12 years old. Include three learning objectives, a 5-minute warm-up, main teaching points with simple examples, two group activities, five check questions, and homework. Use easy English."

Step 3: Read the plan and check it. Read the whole plan. Does it match your class time? Does it match your students' level? Are the examples correct? Fix anything that is wrong. AI can make mistakes, so always check facts, especially in science, maths, and history.

Step 4: Add your own touch. Add a story, a real-life example from your town, a short video, or a question that your students will enjoy. AI gives you the structure. You give it life.

Step 5: Add differentiation. Ask the AI: "Now add one easier activity for struggling students and one harder activity for fast learners." This helps every student learn at the right level.

Step 6: Save it for next year. Save your best lesson plans in a folder on Google Drive or in a notebook. Next year, you can reuse the plan and only change the small parts. Over time, you will build a library of good lessons.

Step-by-Step Guide: Make a Quiz from a Topic

Step 1: Choose your tool. Use Quizizz AI (Wayground), Curipod, MagicSchool AI, ChatGPT, or Twee. Quizizz AI and Curipod are best if you want students to play the quiz online. ChatGPT is best if you want a printed quiz.

Step 2: Give the topic and details. Example prompt: "Make a 10-question multiple choice quiz for Grade 8 about the Solar System. Each question has four options and one correct answer. Include the answer key at the end. Make two easy questions, six medium questions, and two hard questions."

Step 3: Check every question. Read each question and answer. Is the correct answer really correct? Are the wrong options fair, but not too tricky? Are the questions clear? Fix any mistakes. This step is very important, because a wrong answer in a quiz can confuse students.

Step 4: Add different question types. Ask the AI to add two true or false questions, two fill-in-the-blank questions, and one short answer question. Different types make the quiz more interesting and test different skills.

Step 5: Use the quiz in class. Use Quizizz (Wayground) or Curipod for a live game, or print the quiz for a written test. After the quiz, look at the results. Which questions did most students get wrong? That tells you what to teach again.

Step-by-Step Guide: Make a Worksheet for Different Levels

Step 1: Choose your tool. Use Diffit, Twee, MagicSchool AI, or ChatGPT. Diffit is best for reading levels. Twee is best for English. ChatGPT is best for general worksheets.

Step 2: Give the topic. Example prompt for Diffit: "Make a short reading passage about volcanoes for Grade 6, plus 5 vocabulary words with simple meanings, and 5 questions." For ChatGPT, add: "Make three versions: easy, medium, and hard."

Step 3: Check the level. Read the easy version. Is it simple enough for struggling students? Read the hard version. Is it challenging enough for strong students? Change the words if needed.

Step 4: Add activities. Ask the AI to add a matching activity, a fill-in-the-blank activity, or a short writing task. A good worksheet has reading, thinking, and writing.

Step 5: Add an answer key. Always ask the AI for an answer key. It will save you time when you mark the work, and it helps you check if the questions are fair.

Grading Help, Feedback, and Rubrics

Marking takes a lot of time, especially for English, history, and science teachers. AI cannot mark your students' work for you, and it should not replace your judgement. But it can help you work faster and give better feedback.

Make a rubric in minutes. A rubric is a table that shows what makes good work, for example, content, organisation, grammar, and creativity, with marks for each level. Ask ChatGPT, Claude, MagicSchool AI, or Eduaide to make one from your topic and grade level.

Draft feedback comments. You can ask the AI to suggest kind and specific comments, such as "Good use of examples. Next time, add a conclusion." Then you choose the comment that fits and change it for the student. Always remove the student's name before you paste any work into a public AI tool.

Check for common errors. You can ask the AI to list common spelling or grammar mistakes in a piece of writing, so you can teach those points to the whole class.

Presentations, Posters, and Classroom Materials with AI

Use Canva Magic Studio, ChatGPT, or MagicSchool AI to plan a presentation. First, ask ChatGPT to make an outline with slide titles. Then, use Canva to turn it into slides with colours and pictures. Keep slides simple. Use large text, one main idea per slide, and pictures that help students understand. Do not put too many words on one slide.

For posters and classroom displays, Canva Magic Studio is the fastest choice. Type a short description, pick a template, and change the words to fit your class. You can make a poster about the water cycle, a set of classroom rules, or a vocabulary wall in minutes.

Free vs Paid: What Should Teachers Know?

Most AI tools offer a free plan, and for many teachers it is enough. Free plans have limits on how much you can make and on advanced features.

When the free plan is enough:

• You are trying a tool for the first time.
• You use AI a few times a week for small tasks.
• You only need basic lesson plans, quizzes, and worksheets.
• You are happy to copy and paste results into your own documents.

When you might need a paid plan:

• You use AI every day for many classes.
• You need unlimited lessons, quizzes, or generations.
• You need to save and organise many lessons in the tool.
• Your school wants extra safety controls for students.

Start free. Try two or three tools for two weeks. If you hit the free limit every day, then check the official website for the current paid plan and compare two or three tools before you pay. Ask your school first — many schools already pay for a tool, or can apply for free education plans such as Canva for Education.

Student Privacy and Safety: What Every Teacher Must Know

AI tools are powerful, but they also need care. As a teacher, you protect your students. Before you use any AI tool with student work or student data, read this section carefully.

Do not share personal student data. Do not paste student names, photos, addresses, phone numbers, grades, medical information, or other personal details into a public AI tool. Most free AI tools are not made to store private student data. If you need feedback on a student's essay, remove the name first, or use a tool that your school has approved.

Check your school policy. Every school has different rules about AI. Some schools allow teachers to use AI for planning, but not for marking. Some schools allow AI for teachers, but not for students. Some schools have a list of approved tools. Always ask your school leader or IT team before you use a new tool with students. If you are not sure, use AI only for your own planning, not for student data.

Teach students to use AI honestly. If students use AI to do all their homework, they will not learn. Make clear rules. Teach students to use AI for ideas, explanations, and practice, but to write their final work in their own words.

How to Write Good Prompts: The Secret Skill

A prompt is the instruction you type into an AI tool. Good prompts give good results. Bad prompts give vague or wrong results. Learning to write good prompts is the most important AI skill for teachers.

A good prompt has five parts:

1. Role: Who should the AI act as? Example: "Act as an experienced Grade 6 science teacher."
2. Task: What do you want? Example: "Make a lesson plan."
3. Topic: What is the topic? Example: "About the water cycle."
4. Audience: Who is it for? Example: "For 11-year-old students."
5. Format: How should it look? Example: "Use headings, bullet points, and include five quiz questions with answers."

Put these five parts together, and you will get a much better result than if you only type "Make a lesson plan."

Tips to Get the Most from Free AI Tools for Teachers

Start with one or two tools. Do not try twelve tools in one week. Pick the tool that solves your biggest problem and learn it well.

Save your best prompts. When a prompt gives a great lesson plan or quiz, save it in a document. Next time, change only the topic and grade.

Always check AI work before class. Read every lesson plan, quiz, and worksheet. Fix wrong facts and adjust the level for your real students.

Reuse and build a library. Save your best lesson plans, quizzes, and worksheets in Google Drive. Next year, you only need to change the small parts.

Share what works with other teachers. If a tool saves you time, tell a colleague. Good teaching ideas spread fast in a staff room.

Use AI for the repetitive work. Let AI do the first draft. Use your own time for stories, discussions, and personal feedback — the parts only a teacher can do.

Common Mistakes Teachers Make with AI

Mistake 1: Copying AI work without checking. AI can make mistakes. If you copy a lesson plan or quiz without reading it, you might teach wrong facts or give students a wrong answer. Always read, check, and fix AI work before you use it in class.

Mistake 2: Using AI for everything. AI is a helper, not a replacement for teaching. If you use AI for every lesson, every worksheet, and every email, your teaching can become boring and generic. Use AI for the repetitive work, and use your own creativity for the parts that matter most, such as stories, discussions, and personal feedback.

Mistake 3: Sharing student data. This is the most serious mistake. Never paste student names, grades, or personal details into a free AI tool without school approval. Remove names and personal details first, or use a school-approved tool.

Mistake 4: Letting students copy AI answers. If students use AI to do all their homework, they will not learn. Make clear rules. Teach students to use AI for ideas, explanations, and practice, but to write their final work in their own words.

Mistake 5: Using too many tools at once. Many teachers try 10 tools in one week and feel stressed. Start with one or two tools. Learn them well. Add a new tool only when you need it.

Mistake 6: Forgetting your students' level. AI does not know your students. It does not know that one student needs simpler text, or that another finishes work very fast. Always adjust AI work for your real students. Add easier and harder versions when needed.

Mistake 7: Trusting AI prices and limits from old articles. Free plans change. A tool that was free last year may have new limits this year. Always check the official website for the current free plan and limits before you plan your lessons around a tool.

FAQs

What is the best free AI tool for teachers?

There is no single best tool for every teacher. ChatGPT is best for general tasks, MagicSchool AI is best for teacher-specific tasks, and Quizizz AI is best for quizzes. Start with the tool that solves your biggest problem, and try the free plan first. Check the official website for the current free plan and limits.

Are AI tools free for teachers?

Many AI tools offer a free plan for teachers. Some tools, such as Canva for Education, offer extra free features for eligible teachers and schools.

Can AI replace teachers?

No. AI cannot replace teachers. AI can help with planning, quizzes, and paperwork, but it cannot understand students' feelings, build trust, or give personal encouragement. Teachers are needed for real learning, care, and guidance.

Is it safe to use AI tools with students?

It can be safe if you follow your school policy and do not share personal student data. Use school-approved tools, do not let students create accounts on unapproved tools, and teach students to use AI honestly. Always check your school rules first.

Can I use ChatGPT to make lesson plans?

How can AI help with grading?

AI can help you make rubrics, draft feedback comments, and find common errors in student work. It can save time, but you should always check the work yourself and make the final decision on grades. Do not paste student names or personal details into a public AI tool.

What should I do if AI gives a wrong answer?

Do not use the wrong answer in class. Check the fact from a trusted book or website, fix the mistake, and tell the AI to try again with the correct information. Teach students to check AI answers too, and not to trust everything AI says.

How do I start using AI as a teacher?

Start small. Pick one tool, such as ChatGPT or MagicSchool AI. Try one prompt to make a lesson plan or a quiz. Check the result, fix it for your class, and use it. Use the tool for two weeks, then try a second tool. Save your best prompts, and share what works with other teachers.
