Memex is an open-source memory layer you own, shared by every AI agent you use. Your repo remembers the code; Memex remembers you: preferences, decisions and the reasons for them, corrections, people and plans. It is an MCP server that runs on your own Supabase project (Postgres + pgvector), and nothing is hosted by anyone else. I tested it with Claude and Muse reading and writing the same memory; Codex, opencode and other MCP clients connect with a URL and a key. Agents sync with a short phrase ("sync memex"), you decide per agent what it may save, and an optional morning sync can pull, or pull and save, under limits the server enforces itself, with a one-line undo. Anything that looks like a secret is fenced off: never embedded, never sent to a model, hidden from search and sync. A nightly "Dreaming" job, powered by Meta's Muse Spark through the Meta Model API, tags, connects and summarizes memories, marks corrected facts as superseded, and writes overview notes for each topic. Setup is one sentence to an agent ("set up Memex using this repo") and was tested end to end on a brand-new Supabase project. Everything in the repo was written during the hackathon (from Oct 26). It builds on ideas from Open Brain by Nate B. Jones and on my earlier write-up; no code from either was reused, and both are credited in the README.
