Why this exists

I never stuck with spaced repetition. Not because the science is wrong. Because the deck was empty.

You open the app. You mean to write cards. You don’t. So you never review. So you quit. I did that for years. I did not want my kids to do it too.

So the agent writes. You look at what it wrote. You keep the true ones. Then you study.

That is Cards.Fast.

Sign up on app.cards.fast. Free is one deck and a hundred cards. Paid is $5 a month or $36 a year. Family is $10 a month or $60 a year for four seats. Pricing if you want the numbers.

The loop

Connect ChatGPT, Claude, or Grok. How is on Start with an agent.

Imported cards, agent cards, and cards a friend shared sit in Inbox. Cards you type skip it. Accept, edit, or throw them out. Nothing is due until you say so.

You can put a picture on a card you write. Question or answer. About 2 MB.

Import Anki, CSV, or Markdown on app.cards.fast/import. Pictures come over. The old schedule does not. Those cards land in Inbox, held.

You can send a copy of a deck you own. They choose to import. Cards land in their Inbox. Yours stays yours. Not live sync.

Then Today. Reveal the answer. Again, Hard, Good, Easy. The schedule is FSRS-5. We did not invent a scheduler. Paid review can speak the question. Extra and the answer can speak too. Off by default.

When you want to leave, take Markdown, Anki, Mochi, or CSV with you. We are not a lock.

The wiring, if you want it, is Dev tools.
