Questions
A tutor, not an answer key.
Claude, Grok, or Gemini asks you about the card. You say it in your own words. You do not just flip it over.
Flashcards that stay with you
Remember it next month, not just tonight.
Answer questions instead of peeking at the back. The mountain at the top of every page is your progress — it rises when you still know a card later, and it falls when you forget.
Retention 0.00 m · Mount Wycheproof awaits you · how much you still remember
Schedule
It waits until you would forget.
Cards you know come back in days or weeks. Cards you miss come back tomorrow. Closing the tab does not reset that.
Progress
The mountain is not a sticker.
Altitude is a retention score — how much you still remember, written as meters. Color starts at the first mark (1.00 m). Harder material and cards that still stick weeks later move you farther up.
Every device
Computer and phone, same decks.
Sign in with Google and your cards follow you. Study on a Windows PC, a Mac, or a phone. Claude, Grok, or Gemini can add cards; you review them here.
- One Google account on every device.
- You can still study on this device without signing in.
- Connect Claude, Grok, or Gemini if you want them to add cards for you.
Retention below the first mark. Black and white.
Mount Wycheproof · 43 m
Mount Wycheproof awaits you. Everyone starts here in black and white. When your retention score hits the first mark, the photograph turns to color.
Still remembered. Not just seen.
Everest · 8,849 m
Everest means you still remember a large, hard library weeks later — not cards you only looked at last night. Sign in to see K2, Makalu, and the rest.
