For math-heavy courses
Upload your course. Upload your work. Know exactly what to study next.
Photograph your handwritten attempts — or upload the PDF. Inkproof checks them line by line against your own course notes, marks the first mistake that matters, and returns a typeset page you can keep.
- Checks against your material
- German, French or English
- Setup confirmed. Your choice of parts was right — it says so first.
- First real error. The parts formula carries a minus sign; yours dropped it.
- Tied to your own work. Your derivative check on page 1 already flagged it.
Real output. One page from Analysis I, the seeded demo course — open the full PDF .
The loop
upload · check · know what's next1.
Your corpus
Upload lecture notes, problem sheets and past exams as PDFs. Every page is transcribed faithfully — integrals, sums, matrices — and searchable, page by page.
2.
Your feedback
Photograph a solved exercise or upload it as a PDF. You get a typeset page that checks each step against your material, finds the first real error, and works out the fix.
3.
Your progress
Every attempt updates a topic board and your pace toward the exam date. One panel ranks the single highest-value thing to do next.
- 1. Redo Sheet 4, 2(b) — with the corrected sign.
- 2. Two more parts-integrals; run the derivative check.
- 3. Read the next unread section on series.

"Isn't this just a chatbot?"
There's no chat window. You upload work; it returns a typeset verdict — the first wrong step located, the fix worked out, grounded in the notes you uploaded.
"I don't have time to set anything up."
Sign in with one email and a demo course is already loaded — material, attempt, feedback. Judge the output in about two minutes.
"My notes are in German."
The pipeline is language-neutral: German, French and English material all transcribe and read fine, side by side.
"Another subscription to forget."
The Exam Pass is one payment for one exam season — it lapses on its own. The free plan needs no card at all.
"What happens to my uploads?"
They stay yours, private. Export or delete everything at any time. No trackers, no ads, session cookies only.
"I work on an iPad."
Install it as an app and photograph attempts straight from where you study. Feedback is a PDF — read it anywhere, or print it.
