How it works, one step at a time.
Five durable steps. If one fails it retries from where it stopped — never from page one, and never billed twice.
- 0.3s
Scan
Shoot pages from a notebook, textbook, syllabus or past paper. Edges are detected on device before upload.
- 11.4s
Read
Handwriting, tables, formulas and per-word bounding boxes are recovered, so every line keeps its coordinates.
- 4.1s
Structure
Chapters, topics, concepts and formulas are detected — and low-confidence regions are flagged rather than guessed.
- 3.8s
Generate
Questions are written from retrieved chunks only. Nothing outside your source can enter the paper.
- 1.2s
Verify
Each question is re-checked against its chunk. Anything ambiguous is held and never reaches you.
Upload a PDF or photograph your notes. We extract the text, split it into passages, and index it.
When you generate a quiz, questions are written only from those passages, and each one must cite the passage that proves its answer. A separate verification pass rejects questions that are ungrounded or ambiguous.
Question selection and shuffling are deterministic — a seeded algorithm, not a model — so results are reproducible and auditable.
Long-running work happens in the background. You get a job you can watch, cancel, or come back to.
