Lore

Open-source shared persistent memory for AI agents, backed by Notion. A Lore vault is a Notion page with Projects, Topics, Memories, Entities, and Facts databases so later sessions and people can reuse experiential knowledge, follow-up tasks, decision records, and procedures. Age

Why the Score is 6

How Score works

Score v2 uses only observed signals. The displayed contribution is weight × value × 100. Missing factors are insufficient evidence.

[ Claims ]

Publisher-asserted record

Claims are what the publisher declares. Score uses observed signals, not these assertions, except for checklist fields derived from interfaces. MCP, API, cost, and license claims are marked verified, unverified, or contradicted from intake evidence.

[ Capability slices ]

Compose the useful parts.

memory

Shared agent memory vault

Persistent shared memory for experiential knowledge, follow-up tasks, decision records, and procedures, stored as related Notion pages.

UnknownCompose with this
store

Background memory write

Hooks prompt agents to store information and save it in the background. Facts expire unless reinforced and can be linked with supersedes, scoped, or conflicts_with.

UnknownCompose with this
retrieve

Session context retrieval

Sessions can start with relevant vault context, and agents can fetch and expand stored memories through Lore tools.

UnknownCompose with this
search

Structured vault search

Projects, Topics, Memories, Entities, and Facts are related so agents have a predictable search structure, including fuzzy search across those relations.

UnknownCompose with this

The page states any MCP-compatible agent harness can reference the vault through lore-* MCP tools, while humans can use the same Notion pages or a Lore CLI. It contrasts this with harness-local, model-provider, and single-machine file memory. Exact tool schemas, authentication, and any non-MCP HTTP API are not specified in the retrieved text.

Observed evidence and source claims

Signals carry source, method, and observedAt. Source review dates and evidence basis are shown separately. Unobserved metrics stay insufficient evidence.
