The science
Your brain forgets on a schedule. Mimir reviews on one too.
Forgetting is predictable
Without review, you lose most of what you learn within a few days.
Reviews reset the curve
Each well-timed review brings it back, and makes the memory last longer than before.
Mimir does the timing
It schedules every card for you using SM-2, so you only review what is about to slip.
How it works
Three steps. No streak guilt.

Questions, answered
Short answers to the things people ask most.
A way of reviewing that shows you each card right before you'd forget it. Cards you know well come back less often; cards you struggle with come back sooner. Mimir uses SM-2, a well-studied scheduling algorithm — see how it works.
