AI tools for teachers do the jobs that eat evenings: lesson plans, differentiated worksheets, quizzes, feedback on writing and grading. Our catalogue holds ten built for the classroom, every one rated 4.3 or higher, and every one with a free plan.
Read their pricing pages together and the business model is plain. For the teacher, the tool is free. The school or district pays, on a quote. That’s worth knowing before you start, because the free tier is the product you’re being asked to bring into your building.
The all-in-one planners
MagicSchool AI rates highest here at 4.7. It’s a single workspace of teacher tools, from lesson plans to rubrics to parent emails. It’s free forever, and Plus costs $8.33 a month billed annually or $12.99 monthly. Schools and districts buy an Enterprise plan on a quote.
Brisk Teaching at 4.6 takes the opposite approach. It’s a Chrome extension that works inside Google Docs, Slides and whatever else is already open, rather than a site you visit. It’s free for teachers, and districts buy it on a quote, with consortium pricing for groups of districts.
Eduaide.ai at 4.5 pairs a generator with a resource library, and turns out worksheets, graphic organisers and games built from your own standards. It has a free plan.
SchoolAI at 4.5 is built around Spaces: AI activities a teacher sets up for a class, with a view of what each student is doing inside them. It has a free plan for teachers and prices district rollouts separately.
The single-job tools
Diffit at 4.6 does one thing well: it rewrites a text, a topic or a link at the reading level each student needs, with questions to match. Differentiation is the hardest thing to do by hand at 9pm, which is why it rates so high. It has a free plan.
Curipod at 4.5 has changed direction. Its site now leads with writing practice and instant feedback on student writing, rather than the interactive slide lessons it started with. It’s free for every teacher, and schools and districts buy it on a quote.
Conker at 4.3 generates quizzes and assessment questions aligned to a standard, ready to hand out. It has a free plan.
Quizzes, grading and tutoring
Wayground at 4.5 is the tool you may still know as Quizizz. It renamed itself, and its own home page now carries the new name. It builds assessments, presentations and flashcards, and it’s free for teachers.
Gradescope at 4.5 grades paper and online assessments with a shared rubric, which is why it lives in universities and large departments. It’s owned by Turnitin, and it’s sold to institutions on a quote rather than to individual teachers.
Khanmigo at 4.4 comes from Khan Academy, a nonprofit. Its pricing page says it straight: free for teachers, and $4 a month for parents and learners who want the tutor.
Why the teacher doesn’t pay
Every tool above has a free plan, and the pricing pages we checked on 25 September 2026 split the same way. MagicSchool, Brisk, Curipod and Khanmigo are free for the individual teacher. Brisk, Curipod, Gradescope and MagicSchool’s Enterprise tier are priced for schools and districts on a quote.
It’s the same model as most classroom software. A free tool spreads teacher to teacher, and the paid contract follows once enough of a building uses it. That’s fine, but it means the free version you try is also the start of a purchase decision someone else will make.
It also explains the timing. Half of these ten arrived in 2023, in the year after ChatGPT launched: MagicSchool, Eduaide, Diffit, SchoolAI and Khanmigo. Our study of AI tool pricing found the same founding spike across the whole catalogue.

Common questions
Are AI tools for teachers really free?
For the individual teacher, mostly yes. All ten have a free plan, and four are free for teachers outright. The paid versions are sold to schools and districts, usually on a quote rather than a listed price.
What about student data and privacy?
Ask before you paste anything about a student into any of them. Brisk and MagicSchool both state their privacy standards on their own sites, and most districts keep a list of approved tools. If your district has one, that list decides, not the free tier.
Can AI grade student work?
It can speed grading up, and Gradescope is built for exactly that. But it works by grouping similar answers so a person grades each group once. Treat any AI grade as a draft for you to confirm, not a mark.
Where do students fit in?
These tools are for the teacher. For tools students use themselves, see our guides to AI tutoring tools and AI study guide makers.
