## Summary

ChatAndBuild has launched Living Brain, a shared memory that AI apps such as ChatGPT, Claude, and Cursor can access and edit. Memories saved in one tool can be recalled in another, so users can switch tools without re-explaining context. Memories and chats are stored as pages that update when something changes, keeping every connected tool on the latest version. The quoted post from @ladyxtel gives benchmark claims of 92.2% on LoCoMo, 464ms median retrieval, and up to 22.6x fewer tokens per question.

## Why it matters

The source describes a shared memory layer that AI tools can read and edit, a practical way to carry context between assistants.
