You used to know things. Then you got good at looking things up. Then you stopped knowing.
Knowing things is its own kind of fun. It's the difference between fumbling for a phone and just answering. Between spotting a pattern and missing it. Memory is a muscle, and muscles like being used.
This app is built around that small, honest pleasure. Write a card, review it now and then, and watch the things you care about become part of your mind again.
How it works
Write the card.
Question on one side, answer on the other.
Whatever you want to remember.
Forget it on purpose.
You'll practice right before you lose the memory. Saves loads of time!
And then — you know it.
Practice a few times and then ...
the thing just shows up in your mind.
Bold cards,
simple interface.
Your cards should be fun to maintain.
Write cards in markdown. Embed code, math, widgets or custom
html.
How well did you know this?
Your data is yours.
Export everything as Markdown or JSON, anytime. No lock-in. No subscription jail. We're just the shelf your knowledge sits on.
A few minutes,
most days.
That's the whole habit. The little green squares are just the trace of someone who keeps showing up — and the person who shows up is the one who ends up knowing things.
