Join a guild
A guild is a shared deck on one subject. Pick how many new cards join your stack each day, in order or shuffled, and how well-voted they must be.
THE LEITNER SYSTEM · RANKED F TO S
Climb every fact from F-Rank to Legend.
Study Guild is a flashcard community. Guilds share one deck per subject, members add and vote on the cards, and your own stack climbs rank by rank until every card reaches S.
The rank ladder
Answer right to climb one rank; miss and the card drops back to F-Rank. Higher ranks come back less often, so your time goes where it is needed.
How it works

Climb the ranks
Every card starts at F-Rank. Get it right when it is due and it climbs a rank and waits longer: 1, 2, 4, 8, then 16 days. Miss it and it drops back to F-Rank.
- 3
Reach S
A card that clears A becomes Legend: mastered, with a check every 30 days. Your streak, daily goal and Guild XP keep score.
