How it works

  1. 1

    After each exchange, an LLM extracts durable facts (preferences, identity, relationships, ongoing plot threads) — this runs after the reply is already sent, so it never slows down the conversation.

  2. 2

    Each fact is embedded and compared against existing memories from the same conversation; near-duplicates update the existing memory instead of piling up.

  3. 3

    When you send a new message, it's embedded and compared against every memory in scope — the most similar ones (pinned memories first) are pulled in.

  4. 4

    The retrieved memories are assembled into a short block and injected into the system prompt for that reply.
