AI should sharpen your mind, not replace it.
You do the learning
Tigrus never writes your essay or takes your quiz. It builds the practice that puts knowledge in your head — and keeps it there.
AI clears the path
Scribe drafts clean notes from your sources, generates decks and quizzes, and answers questions — always anchored to your material.
Science sets the schedule
Active recall and spaced repetition are the two most-proven techniques in cognitive science. Tigrus runs them for you, automatically.
Organized like a library, wired like a brain.
Four simple layers hold everything: shelves group your subjects, notebooks hold classes, sections split the units, pages carry the notes. Every AI artifact stays wired to the page it came from.

Tools with receipts.
