The AI tutor that refuses to give you the answer.
Most AI study tools summarize for you and quietly destroy your understanding. Cogniloop drills you. Paste a topic, explain it back in your own words, and let the loop find your blind spots — round by round.

Concept tracker
Live concept map: weak → shaky → solid → mastered.
Adaptive difficulty
Dials in on the concept you're shakiest on. Difficulty climbs as you improve, drops when you're stuck.
Voice input + read-aloud
Say your answer out loud instead of typing. Questions read back to you. Web Speech API — free, no plugins.
LaTeX rendering
Math renders in questions, your answers, and the coaching report. Type LaTeX inline — no tool switching.
8 curriculum packs
JEE, NEET, GATE-CSE, MCAT, AP-CS, ML Fundamentals, System Design, Economics — pre-loaded.
3 study modes
Chill: patient hints, low starting difficulty. Exam: 90-second timer, strict grading. Expert: adversarial, first-principles, no hints.
Streaks + history
Daily streak, 90-day activity heatmap, lifetime stats, searchable session history — all stored locally.
Shareable sessions
Export any session as a link — encoded locally, nothing ever touches a server.
Coaching report
Structured: concept buckets (mastered / shaky / weak), study plan, score trend, Feynman journal prompt, markdown + PDF export.
Keyboard-first
Every action has a shortcut. Press ? to open the panel — navigate, submit, and drill without touching the mouse.
100% client-side
Sessions live in your browser only. No accounts, no servers, nothing ever leaves your device.
Why not just use ChatGPT or Claude?
They can roleplay a tutor. But the moment you say “just give me the answer”, they oblige — and that's the failure mode killing learning. Cogniloop's system prompt is locked, the UI is shaped only for explanation + grading, and your concept progress persists across sessions in a structured way generic chatbots don't surface.
