GPU Brain stores notes and documents as editable Markdown pages. An agent searches for relevant material, reads the underlying pages, performs its task and writes back decisions or new facts. Hosted MCP, a command-line client and an HTTP API reach the same memory store, while people can inspect and edit the pages directly. Links and backlinks connect related records. The design makes persistent context retrievable across sessions instead of relying on whatever remains inside one conversation.[2]

Start at the GPU Brain product page for the search-read-act-write memory loop and a minimal API example. Trying the service requires an account; direct API use assumes familiarity with HTTP and authentication.
