App Sensei is a spaced repetition learning app designed for mastering very large card decks without burnout. A custom spaced repetition algorithm actively balances retention of older concepts, progress through current material, and controlled introduction of new concepts, preventing late review overload and stalled learning.

When a concept is unclear, AI can generate on-demand explanations, mnemonics, or memory-palace style associations. Forgetting leads to new ways of understanding, not just repetition of the same prompt.

Motivation is built into the structure of the system. Learning progress generates an open-ended illustrated novel in multiple genres, with story development driven by what you actually learn and how consistently you study. This creates long-term engagement without relying on points or streaks.

Sensei emphasizes low-friction use, with careful attention to keyboard shortcuts and workflow. It includes ready-made courses in multiple languages and selected science topics, supports easy creation of custom courses, and offers a free, ad-free tier.
