About this app
Meet Lambdio - the AI study companion that helps university students actually remember what they learn.
Most study apps let you forget. Lambdio is built on two evidence-backed mechanisms: interactive AI tutoring that makes you actively recall and explain concepts, and a best-in-class spaced repetition engine (FSRS v5/v6) that schedules each chapter's reviews at the exact moment you're about to forget it. Study less, remember more, retain it for years.
🎓 130+ courses across 10 disciplines
Economics, Physics, Psychology, Statistics, Math, Computer Science, Data Science, History, Law, and Political Science - from introductory to doctoral level, organized into structured learning paths that mirror real university curricula.
🤖 Learn with an AI tutor that adapts to you
• Standard Mode - step-by-step interactive lessons with real-time feedback
• Socratic Mode - the AI guides you to discover answers yourself
📚 Review and test modes
• Chat Review - retrieval practice that pinpoints your knowledge gaps
• Feynman Mode - explain concepts as if teaching a beginner, and the AI probes your weak spots
• Quiz Mode - rapid multiple-choice reviews of each chapter
• Mega Quiz - interleaved quizzes across 3 or 5 chapters to boost retention
• Chapter Quiz - a comprehensive ~50-question exam that earns you a certificate
🧠 Proven algorithm
Lambdio uses a custom version of FSRS, the state-of-the-art spaced repetition algorithm (published at ACM KDD 2022 and IEEE TKDE 2023) that outperforms classic SM-2 schedulers like Anki's. In a May 2026 pilot at Ostroh Academy, engaged students scored up to 14.6% higher on their final exams than the control group.
🏆 Stay motivated
50 levels, XP rewards, achievement badges, learning streaks, and a GitHub-style heatmap turn consistent review into a habit.
