Ranked on published features, free-plan limits and beginner ease (checked 14 October 2026). We have not benchmarked these tools hands-on, and commissions don’t affect rankings.
Teachers lose hours to planning, rewriting resources for different reading levels and making slides. AI can take a first pass at that work, so you spend your time checking and teaching. Here are beginner-friendly tools we’d suggest, with honest notes on student privacy and accuracy.
Our top picks
ChatGPT
Who it’s for: Teachers who want help drafting lesson plans, rubrics, quiz questions, emails to parents and differentiated tasks.
Worth knowing: Answers can sound confident and still be wrong. Check important facts.

Who it’s for: Teachers who want answers and study guides grounded in their own curriculum documents, readings and notes.
Worth knowing: Source-grounded answers still need checking against the original document.
Gamma
Who it’s for: Teachers who want to turn a lesson outline into a first draft of slides quickly.

Canva

How to get started
Check your school, department or employer’s AI policy, including which tools are approved for staff.
Pick one task that eats your time, such as differentiating a reading passage or drafting a rubric.
Try it on a free plan with non-identifying material: no student names, grades or personal details.
Check every fact, reading level and curriculum link yourself before using it in class.
How we chose
We picked tools that save time on common teaching tasks, have a free option, and are approachable without technical skills. We used official feature and pricing pages and our editorial judgement; we haven’t run classroom trials. Each school context is different, so treat this as a starting list.
Planning and differentiation: ChatGPT or Gemini
A general assistant is the most flexible tool for teachers. Give it context and constraints: “Year 8 science, 50-minute lesson on the water cycle, mixed abilities, include one hands-on activity and an exit ticket.” Then ask for an easier and a harder version of the main task. It’s also useful for rubrics, quiz questions with answer keys, and polite emails to parents. Always check facts and curriculum alignment yourself; these tools can be confidently wrong. If your school uses Google Workspace, Gemini may fit better, and Claude is good with long documents. Our ChatGPT vs Claude vs Gemini comparison helps you pick.
Work from your own materials: NotebookLM
NotebookLM answers questions using the documents you upload, such as a unit plan, readings or a syllabus, and points back to the source. That makes it handy for building study guides, revision questions and summaries that stick to what you actually teach. It’s free with a Google account. Only upload material you have the right to use, and never student work with identifying details unless your school has approved it.
Slides and handouts: Gamma and Canva
Gamma turns an outline into a first draft of a slide deck in minutes; its free plan gives 400 one-off credits, so it’s a trial rather than ongoing free use. Canva is better for worksheets, posters and slides where you want design control, and many teachers already know it. See Canva vs Gamma and the best AI presentation tools.
Simplify reading passages: QuillBot
QuillBot (opens in new tab) (paid link: we may earn a commission) rewrites text in modes such as Simple and Formal, and its summariser shortens long passages. For teachers, that’s useful for adapting instructions or a reading for students who need simpler language, including EAL/D learners. Check that the rewrite keeps key terms and doesn’t change the meaning, especially in science and maths. The free plan covers the core tools; Premium was AU$12.49 a month billed annually on QuillBot’s Australian page when we checked. See how to use QuillBot.
Explainer videos: Synthesia
Synthesia (opens in new tab) (paid link: we may earn a commission) turns a written script into a video with an AI presenter, and can import slides. Teachers and trainers use it for flipped-classroom explainers, revision recaps and instructions that students can rewatch. The free plan includes 10 minutes of watermarked video a month, enough to make a few short clips. Starter was US$29 a month, or US$18 a month billed yearly. Tell students when a presenter is AI-generated. If you’d rather appear yourself, recording your own short video may connect better with your class. See how to use Synthesia.
Student privacy comes first
Don’t paste student names, grades, health information, behaviour notes or other identifying details into consumer AI tools. Many Australian schools and education departments have guidance on which AI tools staff may use and how, so check yours before you start. Where possible, use tools your school has approved and accounts it manages, which usually come with stronger data protections than personal free accounts.
Teaching students to use AI honestly
Your students are probably already using these tools. Being clear about what’s allowed in each task, such as brainstorming yes, writing the final answer no, helps more than a blanket ban. Our best AI tools for students and best AI essay writing tools guides include academic-integrity advice you can share.
Our verdict
Start with ChatGPT or Gemini for planning, NotebookLM for your own materials, Gamma or Canva for slides and handouts, QuillBot for simplifying texts and Synthesia for explainer videos. Start free, keep student data out, and check everything before it reaches your class.
