Grandmaster Flash: Languages

Grandmaster Flash connects your assistant to a private language flashcard library. Ask Claude or an eligible ChatGPT workspace to create a deck, then practise on your iPhone or iPad.

CREATE DECKS FROM A REQUEST
Tell your assistant the language and situation you want to practise. It can research vocabulary, add translations and example sentences, generate audio, and save the cards directly to your library. You can also ask it to make cards from text, an article, or a screenshot you supply.

PRACTISE ON YOUR PHONE
See a prompt, think of the answer, reveal it, and choose Remembered or Forgot. Cards you know return less often; cards you miss return sooner. Reading, listening, writing, and speaking each have their own practice schedule. Writing and speaking are self-assessed.

LISTEN TO YOUR CARDS
Play generated audio in the voice selected for your deck, or recordings you supply through your assistant. Choose whether audio plays automatically during study.

STUDY OFFLINE
Decks and audio download to your device. Practise without a connection, then sync your reviews when you reconnect. Sign in on an iPad with the same account to use the same library and practice history.

KEEP YOUR LIBRARY USEFUL
Flag a card that needs attention and ask your assistant to correct it. Suspend cards, archive decks, or delete content from the app. Content creation and editing happen in your assistant.

PRIVATE ACCOUNTS
Sign in with an email code. Choose which assistants can access your library and revoke their access in Settings. You can also delete your account and its synced content in Settings.

GET STARTED
An email account and a compatible assistant with MCP connector support are required. Connect Grandmaster Flash to Claude or an eligible ChatGPT workspace and use the same email in the app. Your assistant provider's account requirements and terms apply.
