Era Brain — Era Docs

Drop-in long-term memory for AI agents and apps — add, search, graph and forget, with real permissions. SDK, CLI, REST API, MCP and a Claude Code plugin.

Era Brain is long-term memory you can give any agent or app. Your agent saves what is worth keeping — a preference, a decision and its reason, a fact about a customer — and recalls it before it answers, next week, in another tool, for another person on your team who is allowed to see it.

It is the same memory Era's own assistant uses for your business, offered on its own: you do not have to set up anything else in Era to use it.

What you get

Hybrid recallFull-text (Turkish and English) and local embeddings side by side, fused by rank. When two facts disagree, the newer one comes first.A graph, not just vectorsFacts are linked to the people, companies and products they name. Typed paths answer 'how is X connected to Y'.Permissions built inWorkspace-scoped keys, private memories, module-scoped facts, OAuth scopes brain:read and brain:write — re-checked on every call.ExplainableAsk why a fact was returned: its rank in each leg, the words and entities it shares with the question, and why you may see it.
