Checkmate turns your notes, PDFs and courses into slides, tests, flashcards and study guides — then helps you grade, spot what each class needs and sync grades to PowerSchool. You stay in charge of every word.

Copilot for slides
Describe the lesson and Copilot builds or edits the deck by working through your own courses and uploads. Choose a class and it looks at that class’s results to focus on what they found hardest.
Units, lessons, notes, uploaded files and links. Everything you generate can draw on them.
Present from the browser, share a view link, or export when you need a file.
“Split slide 4”, “simpler words for Grade 6”, “add a quick check” — small, precise edits.
Ask for feedback on a deck without letting Copilot change anything.
Beyond slides
Assessment, practice and feedback built on the same materials — so nothing needs to be set up twice.
Tell Copilot what you need — “set up Biology 9 with these eight units and make a quiz for unit 1” — and it creates the course, adds the units and starts the quiz from your materials. It works from any page, or full screen.
Generate questions from your materials across 11 question types, from multiple choice to essays and code. Objective questions grade instantly; written answers get suggested scores and feedback that you review and override.
Turn a course unit, a PDF or your notes into a flashcard set. Each student’s review schedule adapts card by card, so study time goes to what they haven’t mastered yet.
Build study guides and printable or online worksheets from the same course materials, then edit anything before it reaches students.
On document assignments where you switch it on, students can ask for feedback, help getting started, a thesis check or a clarity pass. The coach asks questions and points at their own words — it doesn’t hand over sentences.
Tests, worksheets and documents waiting for you land in one queue. Review suggested grades, leave feedback and return work without hunting through classes.
Connect with your PowerSchool sign-in and release grades to your gradebook. Checkmate never sees your PowerSchool password.
How it works
Set up a course, add your syllabus, notes, PDFs, slides and links — Checkmate finds your units automatically. Everything else builds on them.
Make slides, tests, worksheets, flashcards or a study guide for any unit or lesson — then change anything. Nothing goes out until you publish it.
Assign to classes, grade from one inbox, watch class results and release grades to PowerSchool.
Academic integrity
Copying, looking answers up mid-test and passing off AI or someone else’s writing as their own shouldn’t fly. Checkmate is built to make cheating hard to do and impossible to hide — with evidence you can see, not a black-box score.

Checkmate watches for the moves students use to look things up mid-test, and shows you exactly what happened.
Instead of guessing whether text is “AI-written”, Checkmate records how the work was actually made.
Students get help thinking, not a ghostwriter. You decide per assignment whether the coach is on.
No software can stop every form of cheating. Checkmate makes it hard to do, easy to spot, and leaves the decision with the teacher.
For every audience
Tell Copilot who you’re presenting to and it changes the structure, tone and examples to fit.
Lessons that build step by step, with check-for-understanding moments and an exit ticket. Point Copilot at a class and it targets what that class found hardest.
Sessions for colleagues open with an agenda and goals, include think-pair-share prompts, and close with a concrete next step for Monday — no childish examples.
Curriculum nights and info evenings in plain, jargon-free language: what students will learn, how families can help at home, and how to get in touch.
Also works for leadership and board updates, clubs, conferences and self-study.
Security & privacy
Checkmate is built by students, for schools. We collect what’s needed to teach and nothing for advertising, and we keep teachers in control of everything the AI produces.
Schools are set up by request, teachers join by invitation, and students join classes with a teacher’s code.
Students see only their own work; teachers only their classes; each organization’s data is kept separate.
Passwords are hashed with bcrypt, reset links are single-use and expire, and PowerSchool tokens are encrypted at rest.
Student AI is off until a school enables it, with per-student limits. Sign-ins and admin actions are audit-logged.
Not without it showing. Tests run with fullscreen, tab-switch and copy/paste checks and can lock on a violation. Written work keeps a full writing replay, so text pasted in from elsewhere stands out. Checkmate gives you evidence rather than an AI-detector guess — you make the call.
A school administrator requests access from the Get started page. Once the organization is set up, the administrator is invited as its owner and can invite teachers by email.
No. Students create their account by joining a class with a code from their teacher, so every student account belongs to a class.
Objective questions (multiple choice, true/false, numeric and similar) are graded instantly. Written answers get a suggested score and feedback that you can review, adjust or override before returning work.
From what you give it: your courses and uploaded materials, plus aggregate results for a class you choose. It is instructed never to invent statistics, quotes, citations or class data — if it doesn’t have a source, it leaves it out or asks.
The things you can do yourself: set up courses and units, create classes, make slides, quizzes, worksheets and flashcards, check what needs grading and start AI grading. It only touches your own courses and classes, and anything students would see — publishing, assigning, releasing grades — shows you exactly what will happen and waits for your click.
Only if their school turns it on. Student AI features are off by default and rate-limited per student, and the writing coach is enabled per assignment by the teacher.
Yes. Teachers can connect PowerSchool to release grades to their gradebook, and push flashcard sets to Blooket.
