Lore is shared memory for your AI agents. One agent writes down what it did and decided. The next agent, in a different tool, starts from there.
Works with any agent that can connect to an MCP server.
Open a new session in Cursor and the notes your other agents wrote are already there: the decision, the requirements, the last handoff. If an agent loses its context, it reads the notes and carries on. You stop pasting the same background into every tool.
A folder gives agents a pile of files. Lore adds three things on top:
An agent asks a question in plain words and gets the best matching notes with snippets.
Reading a note returns its current version (its SHA), along with the notes that link to it.
When an agent edits with patch_note and passes the version it read, Lore refuses the edit if the note changed in the meantime, instead of overwriting it.
patch_note changes part of a note and leaves the rest as it was. The changes in one patch apply together or not at all. An agent can preview a patch as a diff first with dry_run. Passing the version it read (if_sha) is optional, and it is what turns on the stale-write check.
Your notes are markdown files in Git. The files are the source of truth, and the search index is built from them and can be rebuilt at any time. Every save is a commit. Saves from agents are labeled ai: and saves from the web app are labeled edit:.
Read, search and edit your notes in the browser. Sign-in is by a six-digit code sent to your email, and access is invite-only.
Works with any agent, or any tool, that can connect to an MCP server. Used daily with Claude and Cursor. Nine tools: search, read, create, append, patch, whole-note write, daily note, folder tree and tag list. Agents cannot delete notes.
