Typed facts on a graph, two clocks per fact, hybrid retrieval, conflict-aware ingest, and a GDPR forget that actually deletes. Over REST and a native MCP endpoint. Website · Docs · Blog · Quick start · Contributing --- Most \"memory\" for AI agents is a vector store: embed text, return what looks similar. That can't tell you when something was true, can't reconcile two sources that disagree, and can't truly delete a user on request. Brain is a per-tenant knowledge graph built for those jobs — a system of insight, not a system of record . ✳ = extension points for third parties — see Build on Brain. Why Brain - Two clocks per fact. Every fact carries valid time (when it was true) and transaction time (when Brain learned it). Query now , or replay exactly what the graph knew on any past date. History is replayed, never rewritten. - Graph-first retrieval, not a cosine match. The unit of retrieval is a typed fact on the graph — never a text chunk. Vector + BM25 (+ HyPE) are only the doors in : they seed candidate facts from a free-text query, and everything after is graph-native — ontology-driven predicate/type router, per-entity bucketing with degree boost, 1-hop edge expansion, tier-aware PPR over the candidate subgraph, then cross-encoder + listwise LLM rerank, with bitemporal closure and trust/corroboration multipliers throughout. Queries that already name their anchors skip the doors entirely: ","default_branch":null,"files":null,"tree":[],"storefront":"/r/inite-ai","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/inite-ai/inite-brain-service/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
