Use Masterki with AI apps

Last updated: October 15, 2026

Masterki can take flashcards from ChatGPT, Claude, Gemini, and Grok and hold them until you review them in the app. Nothing is added to a deck until you accept it. The AI app cannot read your existing decks or your conversation. It only sends the cards you ask it to save.

Before you connect

  1. Install Masterki and sign in.
  2. Open Settings → Connect Masterki to AI apps.
  3. For Claude, Gemini, or Grok, copy the server URL: https://masterki.org/mcp. ChatGPT doesn't need it.
  4. Tap Get a pairing code when the sign-in page asks for one. The app copies it for you, and Copy copies it again. The code lasts 10 minutes. You can also sign in with your Masterki email and password.

ChatGPT

Open Masterki in ChatGPT's app directory and choose Connect. Sign in with a pairing code.

Then ask: "Make flashcards from this and save them to Masterki."

Claude

In Claude, open Settings → Connectors and choose Add custom connector. Name it Masterki, paste the server URL, then connect and sign in with a pairing code.

In Claude Code or Cowork, install the Masterki plugin when it is listed, or add the same server URL as a custom connector. The first time Claude saves cards, it opens the Masterki sign-in page.

Then ask: "Make flashcards from this and save them to Masterki."

Gemini

Custom apps in Gemini need a personal Google Account, age 18 or older, in the US, with Activity turned on. On a computer, open gemini.google.com, then Settings → Connected Apps → Add a custom app. Paste the server URL and leave the advanced credential fields empty. Sign in with a pairing code.

Grok

Open grok.com/connectors, choose New Connector → Custom, paste the server URL, and sign in with a pairing code.

After the cards are saved

Open Masterki. The cards wait on Home until you review them and add them to a deck. They are labelled with the AI app that sent them. Cards stay on Masterki's servers only until the app saves them, and at most 500 wait at once.

Disconnect

In the app, open Settings → Connect Masterki to AI apps and disconnect the app. You can also remove the connector inside ChatGPT, Claude, Gemini, or Grok. Disconnecting revokes that app's access.
