Living Brain launches a shared memory layer for ChatGPT, Claude, Cursor, Codex and custom agents

A startup launched Living Brain on X on November 4, describing it as one persistent memory kept outside the model, shared by ChatGPT, Claude, Cursor, Codex and users' own agents: what one tool writes, any other can retrieve. The launch post claims 92.2% on the LoCoMo memory benchmark, a median retrieval time of 464 ms and up to 22.6 times fewer tokens per question. These figures are the company's own and not independently verified.
