How it works

Two modes, one philosophy

PACT Mode
Progressive learning

New to a subject? PACT introduces cards progressively, mixing fresh material with spaced reviews so you build knowledge without drowning in unknowns. Designed for decks you’re learning from scratch.

Anki Mode
Spaced repetition

Already familiar with your material? Rate each card by recall difficulty and let the algorithm schedule your next review at the optimal interval. Classic SRS, refined and distraction-free.

01
Deck & box organization

Group decks into boxes for any subject. Create, edit, and manage cards with reversible front/back support.

02
Progress tracking

Per-deck completion bars, Anki distribution charts, streak counting, and detailed session metrics.

03
Trial mode

Study with a mistake budget. Push your retention further with timed, high-stakes review sessions.

04
Keyboard-first

Full keyboard shortcuts throughout—Space to flip, arrows or number keys to rate. Fast, frictionless study.

05
Dark & light modes

Study comfortably at any hour. System-synced theme with manual override.

06
Secure & private

Passwordless email login. Your decks live in your account—no third-party sync required.
