How well did you recall it?

It's not your memory.
It's timing: one more look before it fades.

Just learned it. You remember everything.

The moment you close the book, your memory is full. It won't stay that way.

Leave it alone, and it slips away.

A few days later, most details are blurry. Rereading means starting over.

Bring it back right before you forget.

No need to reread everything every day. When a card is about to fade, MindCryst asks you to recall it once.

Each recall pushes the next one further out.

10 minutes, 1 day, 3 days, a week, three weeks. The gaps grow, and so does your memory.

  • Faithful to the sourceNo padding. Your material is never rewritten into something else.
  • Every word is editableTitles, tags, text, and blanks stay editable before and after saving.
  • Saved means scheduledCards go straight into your review queue, not into a forgotten folder.

AI drafts.
You decide.

Generating is not the end. Before saving, compare with the source, fix answers, and delete anything that is off.

Will AI change what I meant?

AI gives you an editable draft. The source and the result sit side by side, so you can check and edit every word before saving.

Why not review every card every day?

Every recall changes when a card comes back. Forget it and it returns sooner; recall it easily and it waits longer.

What can I put in?

Course notes, web pages, mistakes, and book highlights. Anything can start from a block of text.

Can I keep editing after generating?

Yes. Titles, tags, text, and blanks all stay editable, and edited cards go back into the review queue.
