UML is one private memory graph shared by Claude, your agents, and your apps — you can see it, edit it, and own it.
Tell your AI: "save this to uml — I finished Unit 3." Or let your app send it automatically.
AI extracts the durable facts. The backend verifies them and writes real structure — never a raw chat dump.
Open the dashboard: a living graph, timelines, organized pages — and a receipt for every single save.
Claude, Cursor, your own agent — all connect to the same private memory. Save once, recall everywhere.
Sign up, create your private memory link in the Connect tab, then paste it into any MCP-capable client — or call the API from your own app.
When UML is connected through an MCP-capable AI client, UML provides memory tools. The client or host model decides when to call them. If you need guaranteed per-turn capture or recall, use the UML API or SDK inside your app or agent runtime.
UML turns useful context from chats, events, documents, tools, and workflows into structured memory objects — entities, facts, events, relationships, pages, and receipts.
Messages are source material. UML keeps the durable meaning that should survive beyond a single exchange.
UML stores verified entities, facts, events, relationships, rollups, and receipts so systems can reason over them later.
The LLM proposes; UML verifies; UML writes. Recall and extraction stay separate.
New evidence can create, update, promote, invalidate, or supersede memory. UML is not an append-only chat log. Your facts live in a visual graph with clusters you can open, search, drag, and edit — not a hidden blob.
Say "actually, that changed" — the old fact is superseded and kept as visible history on a timeline, not deleted, not duplicated.
Each write returns proof: what was saved, updated, or refused — with source and timestamp. No silent writes, ever.
Decide what gets collected and what must never be saved — plain-language rules the backend actually enforces.
UML can ingest useful context from tools, apps, agents, docs, events, workflows, and custom schemas.
No ads. No trackers. No selling data. No training on your memory. Export everything as JSON or delete it all — any time, one click.
UML does not sell user data or use user memory for unrelated purposes. User memory belongs to the account that created it. Connected tools are third-party services and access UML only through private links or tokens you create.
UML is an early product and may change. Use it responsibly. You are responsible for tokens and private links, and you can revoke them from Connect. Avoid sensitive or regulated data unless UML is appropriate for that use.
Free early access — founding users keep the Pro tier free when paid plans launch.
