AI-powered spaced repetition

Studying that doesn't feel like studying

Beautiful flashcards, an AI that drafts them for you, and an engine that only asks about what you're actually forgetting.

O(V + E) for both BFS and DFS.

Everything you need to actually learn

Not just a flashcard app. Every surface is designed around the one thing that matters: remembering what you studied tomorrow, next week, next month.

How it works

Three steps from notes to mastery

  1. Step 1

    Drop your study material

    Paste lecture notes, upload a PDF, or build a deck by hand. Claude extracts the testable facts into editable cards.

  2. Step 2

    Study with spaced repetition

    SM-2 schedules each card based on how well you know it. Just rate Again / Hard / Good / Easy and the queue handles the rest.

  3. Step 3

    Track what sticks

    Mastery rings, heatmaps, and a trouble-cards list show you exactly what's working and what needs another pass.
