How PupilBot helps you learn
Your study materials become an intelligent tutor — patient, adaptive, and quiet enough to read by.
Every kind of question
Single-choice, multi-choice, fill-in-the-blank, matching, numeric, free-form. We pick the right format for what you're learning.
Adaptive difficulty
Questions get harder as you improve. Struggling? We dial it back and reinforce fundamentals.
A mind that remembers
We track how each question fades from memory and bring it back the moment you'd start to forget. FSRS-6 spaced repetition + Bayesian Knowledge Tracing (BKT) for per-topic mastery.
Native iPhone app
Coming soon to the App Store. Camera, OCR, adaptive questions and FSRS-6 review — all in one app, all in your pocket.

The reading
Three steps to mastery
1
Photograph the pages
Open the camera. Snap a chapter, your notes, a few slides. Our OCR engine reads every line and pulls out the key topics.
2
Practice adaptively
Six question shapes, picked for what you're learning. The system tracks where you're strong and where you need practice, adjusting in real time.
3
Remember it
FSRS-6 spaced repetition brings every card back the moment you'd start to forget. Bayesian Knowledge Tracing keeps a running mastery estimate per topic, so we know what still needs work. Practice in the iPhone app — or quietly inside a Telegram chat between sessions.
