TeachTools is the only AI toolkit for teachers that puts student privacy first โ not as a feature, but as the foundation.
๐ FERPA-compliant by design โ student data is encrypted end-to-end and never stored or sold
๐ง 23+ AI-powered generators โ worksheets, quizzes, lesson plans, rubrics, crosswords, bingo cards, and more
๐ Easy Grader โ upload an answer key + up to 100 student papers and get every assignment graded in minutes with per-question breakdowns
๐จ Custom headers & footers โ brand every document with your name, school info, and custom backgrounds so output looks like yours, not a robot's
โก Try before you sign up โ every tool lets teachers fill out the form and preview results before creating an account
Most AI tools sell features. TeachTools sells permission to trust an AI tool in your classroom.
TeachTools's answer:
Every competitor asks teachers to make a trade: use our AI, but hand over your classroom data and hope we do the right thing. TeachTools doesn't ask.
Teachers don't need another AI toy. They need a tool they can actually use without a risk assessment from their district's IT department.
TeachTools's answer:
K-12 teachers who are drowning in prep work and desperate for help โ but can't afford to compromise on student privacy.
That includes: - Classroom teachers across every subject and grade level
First-year teachers who need quality materials now, not after 10 years of building a resource library
Veteran teachers buried in grading who want their evenings back
Teachers in rural and underserved schools who deserve the same resources as well-funded districts
International educators in 15+ countries generating content in multiple languages
Instructional coaches and curriculum coordinators building materials at scale
If you've ever stayed up until midnight making a worksheet, TeachTools was built for you.
TeachTools's answer:
A first-year teacher in rural Oklahoma shouldn't have worse resources than a veteran at a Manhattan private school. But they do โ because great materials take time, and time is the one thing no teacher has enough of.
TeachTools exists to fix that.
We watched teachers spend their nights and weekends building worksheets, writing quizzes, and grading stacks of papers by hand โ burning out of a profession they chose because they love kids. Meanwhile, AI tools kept launching that treated student data like a commodity. "Just paste your roster in!" No thanks.
So we built the opposite: 23+ AI generators that create classroom-ready materials in seconds, protected by military-grade encryption, fully FERPA-compliant, with zero student data ever stored or sold.
The mission is simple: give every teacher the tools to spend their time where it matters โ with their students.
