Cognition for Claude Code
Use Cognition from Claude Code. Cognition is a study app: workspaces for your classes, notes, quizzes and grades, deadlines and a journal. You sign in with your own Cognition account, choose what Claude may do, and can see and undo everything it did from Settings › Connected AI.
The connector is part of Cognition Pro. See the plans at https://app.evolving-cognition.com/subscribe.

What Claude can and cannot do
- It sees only your own Cognition data.
- It asks you before it edits or deletes anything.
- A change to more than one record waits for your review in Cognition.
- Every call is listed in Settings › Connected AI, where you can undo a single change for a limited time, or disconnect Claude.
Skills
- quiz-me: Claude quizzes you on one of your Cognition quizzes, one question at a time, and saves your score to your Grades and Stats if you say so.
