01 / AutoCoach
Read it once.
Remember it
for good.
AutoCoach turns any PDF or slide deck into an adaptive quiz engine. It extracts the concepts that matter, drills you where you're weak, and schedules reviews before you forget — so studying compounds instead of evaporating.

Q.04/10 — B-Trees
Which property keeps a B-tree balanced after insertions?
02 / The problem
You forget 70% of what you read by tomorrow.
Ebbinghaus measured it in 1885 and it hasn't changed: memory decays on a curve, fastest in the first 24 hours. Re-reading and highlighting feel productive but barely bend it. The only interventions that reliably work are active retrieval — being forced to recall — and spaced repetition — recalling again right before you'd forget.
AutoCoach builds both into the way you read. Every document becomes a question source; every wrong answer becomes a scheduled comeback.
03 / How it works
From document to drill in three steps.
Upload
Drop a PDF or PPTX — lecture notes, a textbook chapter, a spec. AutoCoach extracts the text, chunks it, and indexes every passage for retrieval. Most documents are ready in under a minute.
Extract
An LLM reads the document and pulls out the concepts worth knowing — not keywords, actual ideas. Each concept is linked back to the exact passages that teach it, so every question stays grounded in your source.
Drill
Start a session. Questions are generated live against your weakest concepts — multiple choice, true/false, and free-text answers graded by AI. Answer, see why, move on. The next question is already waiting.
04 / Features
Built for remembering, not for collecting documents.

Concept extraction, not flashcard busywork
You never write a card. AutoCoach reads your document and identifies the concepts that actually carry the material, ranks them by importance, and tags the core ones. Every quiz question traces back to a concept, and every concept traces back to the passage it came from.

An engine that adapts every single question
The selector watches your mastery per concept and aims each new question at the gap — weighted toward what you miss, with a recency window so sessions never loop the same idea twice in a row. Free-text answers are graded by an LLM that explains exactly what was missing from your answer.

A review queue that knows when you'll forget
Every concept you've touched gets a review date based on how well you know it. Open AutoCoach and the day's due reviews are waiting — five minutes of targeted recall instead of an hour of re-reading. Miss one and it comes back sooner; nail it and the interval stretches.

Keyboard-first sessions, progress you can see
Answer with 1–4, submit with Enter, next question with Space — sessions move at the speed you think. XP, streaks, and per-concept mastery bars make the invisible work of remembering visible, and the dashboard shows exactly which chapters are solid and which are theater.
05 / The engine
Mastery is a number, and the engine chases it.
Behind every session is a per-concept mastery score, updated after each answer. Correct on a hard free-text question moves it a lot; a lucky multiple-choice guess moves it a little. The selector always aims at your lowest scores, so time spent in AutoCoach goes where it pays the most.
