Tool by tool

MagicSchool

The widest set of teacher tools in one place

MagicSchool bundles 80+ AI tools for teachers, from lesson plans and rubrics to quizzes and writing feedback, plus tools for students. Plus adds more for one teacher, and schools and districts buy an enterprise plan.

Strengths

  • A free plan that covers most everyday planning tasks
  • Built for schools, with privacy terms and district plans

Limits

  • So many tools that finding the right one takes a while
  • Output stays generic until you add your own materials and context
Official site

Brisk

AI inside Google Docs, Slides and the pages you already use

Brisk is a browser extension that works on the page you have open. It creates lesson plans, quizzes and activities, gives feedback on student writing and changes reading levels, across Google and Microsoft tools.

Strengths

  • No new app to learn: it works on the doc or page you already have open
  • Feedback tools for student writing on the free plan

Limits

  • Admin dashboard and rostering only on paid school plans
  • Needs Chrome or Edge
Official site

Eduaide

Lesson planning with many resource formats

Eduaide helps teachers draft lesson plans, worksheets, graphic organizers, classroom games and assessments. The free plan caps how much you can generate each month, and Pro lifts the cap.

Strengths

  • A large library of resource types for planning
  • A free plan to try it before you pay

Limits

  • The free plan runs out fast if you plan every day
  • Unlimited generations and image creation need the paid Pro plan
Official site

Diffit

Leveled readings and resources for mixed classes

Diffit turns a topic, text or standard into readings and activities at different levels, ready to print, download or share. The free plan keeps what you made in the last 90 days, and paid plans add standards alignment and exports.

Strengths

  • Quick differentiation for students at different reading levels
  • Exports to Google, Canva and Microsoft on the school plan

Limits

  • The free plan only keeps your last 90 days of content
  • Focused on readings, less on assessment
Official site

Curipod

Interactive lessons and daily writing practice with feedback

Curipod builds interactive lessons with polls and open questions, and now centers on writing practice where every student gets feedback. Teachers use it free, and schools buy a site licence for more live sessions.

Strengths

  • Every student writes and gets feedback in the same lesson
  • Free for individual teachers

Limits

  • The free plan limits live sessions each week
  • Built for live class time more than homework
Official site

ChatGPT

A flexible all-round assistant for drafts and ideas

ChatGPT drafts lesson ideas, parent emails, examples and quizzes in a chat. OpenAI's ChatGPT for Teachers workspace is free for verified US K-12 educators until June 2028 and does not train on your data by default.

Strengths

  • Handles almost any writing task you can describe
  • The teacher workspace adds admin and privacy controls for schools

Limits

  • Starts from the internet, not your curriculum, unless you upload your materials
  • Answers can sound sure and still be wrong, so check them
Official site

Gradescope

Faster grading of paper and online assessments

Gradescope, from Turnitin, lets you grade scanned paper exams with shared rubrics. Online assignments, code, AI-powered grading and roster matching come with the Institutional plan.

Strengths

  • A rubric you set once applies to every copy of a question
  • Handles paper exams once you scan them

Limits

  • AI grading only on the paid Institutional plan
  • Built for grading, not for making materials
Official site

StudyPDF

That's us

Quizzes, tests and worksheets from your own slides, shared by link

StudyPDF works from your own lessons. Upload slides, worksheets and notes, and it builds quizzes, practice tests and flashcards you check and edit, with a blank worksheet and answer key as PDF. Share the course with one link that opens in any browser. The free plan needs an account, no card, and gives you about 4 materials a week.

Strengths

  • Quizzes export as a blank worksheet PDF with the answer key on its own page
  • One link per course: 3 people can join on Free, 10 on Pro, 30 on Ultra
  • Every question comes from your teaching materials, not the open internet

Limits

  • No classes, gradebook or per-student reports
  • Weekly caps on every plan
Get started free

How we picked

  • We started from the jobs teachers name most: planning, making materials, differentiating, feedback and grading.
  • Free plans and prices come from each vendor's own site, checked October 2026. Prices and limits change, so check before you pay.
  • We sort by task, not by rank. Most teachers end up with one general tool and one or two built for a specific job.
  • Where a vendor shows no public price, as with school and district plans, we give no number.
  • Follow your school's rules on student data before you use any of these with student work.

More on this

Most AI tools for teachers do one of four jobs: plan lessons, make materials, adapt them for different readers, or speed up feedback and grading. Start with the job that eats most of your week. Try the free plan of the tool built for it before you pay or ask your school to.

Check privacy before you paste anything about students. Many schools have approved tools and data agreements, and features like rostering or admin dashboards often sit only in school plans. Read AI output before it reaches students: these tools can get facts wrong or miss your curriculum.
