Your assistant writes the cards. Your village grows when you review them.

Ask Claude or ChatGPT to turn a lesson, your notes or a video into flashcards. They land in your Cristal Memoria decks. Then you review them in a village game: your wheat, milk and cheese come from your reviews.

Get Cristal Memoria, free betaiPhone and iPad, through Apple TestFlight

A Cristal Memoria village at night: a bakery, a barn, fields and the Study button. — Your village in the app. Your buildings are built with what your reviews earn.

What the connector does

From a video to a deck

Paste a YouTube, TikTok or Vimeo link and name a deck. The assistant reads the subtitles, writes cards on what the video really teaches and saves them.

From a lesson to your collection

Basic, reversed or cloze notes. Search, fix, tag and organize your cards, check your statistics and daily limits, all in conversation.

Synced everywhere

Changes reach the app on your devices at their next sync. The connector never answers reviews or earns rewards for you.

Then the game takes over

The Study screen with today's cards and a Study button.

12 cards. One wheat field.

Reviewing is what makes things grow. An hour of play with zero reviews leaves your field where it was, so the game keeps sending you back to your cards.

Press Again. Your wheat still grows.

Every answer moves your crops, whichever button you press. You can rate your memory honestly and your schedule stays useful.

Piet, Suzu, Apus and the other villagers live in the village you build.
