How it Works
StudyStack is built around one idea: repeat what you don't know until you do. No algorithms, no scheduling — just you and the cards.
The Study Loop
1
Load a deck
Drag and drop a .md file onto the home screen. Your deck is parsed instantly and saved to your browser — no account needed.
2
See the keyword, test yourself
Each card shows a keyword. Before hitting Reveal, try to recall the answer. This active retrieval is the core of the method — the struggle to remember is what makes it stick.
3
Sort into two piles
After revealing, be honest. If you knew it cold — Got It. If you hesitated, blanked, or guessed — Memory Hole. No partial credit.
4
Work the hole
When the deck runs out, your Memory Hole cards get reshuffled and you run them again. Each pass, the pile shrinks.
5
Clear the deck
Once every card is in the Got It pile, the session is over. You'll see how many rounds it took, your total time, and a motivational stat.
Key Terms
🧠 Memory Hole
Cards you couldn't recall. These loop back into the next round.
✓ Got It
Cards you knew cold. Once here they're done for this session.
≈ Shaky
Recalled, but not cleanly. Clears the card but flags it to come up first next session.
🔄 Round
One pass through current cards. Round 1 = full deck. Round 2+ = hole cards only.
🏆 Clear
The goal. Memory Hole reaches zero.

Mulligan — rewind to the previous card and re-test it. You start each round with 5, and earn one back for every 3 Got It in a row (capped at 5).
