Everything here has shipped. What's next is on the
[roadmap](/brain/docs/roadmap).

## Knowledge and curation

- **Search by meaning**: semantic retrieval over everything captured, with
  source tracking on every fact.
- **Cited summaries**: per-entity distillations that link to their documents
  and rebuild when a source changes.
- **Context packs**: the relevant summaries, documents and relationships for
  an entity, assembled within a token limit.
- **Obsidian plugin**: two-way sync between a local vault and Brain; search,
  publish and pull the same knowledge base from your notes.

## Skills and handoffs

- **One skills repository**: versioned skill bundles served to every
  connected agent as MCP tools; update one, connected agents pick it up.
- **Handoffs with context**: agents send, reply and watch an inbox; work moves
  between agents with its context attached.
- **Delivered on reconnect**: handoffs that arrive while a watcher is down are
  delivered on its next watch.
- **Work sessions and todos**: an agent starting cold can ask what it was
  doing and what is still owed.
- **Dated reminders**: park a fact against a future date (a cert expiry, a
  decision to revisit) and it stays out of the way until then. Brain answers
  "what's due in the next 30 days"; acting on it is your scheduled agent's
  job, not a notification we send.

## Models and privacy

- **Hosted lane**: hosted mode runs every model call on LLMs Levirge hosts;
  no third-party model provider in the path.
- **Cloud when you want speed**: switch to third-party LLMs from Settings at
  runtime; no redeploy.
- **Local embeddings**: vector generation and reranking run on Levirge
  infrastructure in both modes.

## Access and operations

- **Tenants and Vaults**: knowledge is partitioned per Vault; personal Vaults
  are private to their owner and fail closed.
- **Per-writer attribution**: every document records whose agent captured it,
  and facts drawn from it inherit that.
- **Scoped tokens**: hosted sign-in, or bearer tokens you issue and revoke,
  optionally limited to chosen Vaults and made read-only. Only the hash is
  stored.
- **Ingestion you can see**: a board of pending, errored and promoted items,
  with one-click retry and a health endpoint.
