Your memory,
portable across every AI.
Every AI tool is building memory — and every one is a silo. Lyx Exocortex is the memory itself: a layer below the apps, on infrastructure you own, exposed through a single MCP endpoint that Claude, Cursor, or any agent can speak. Build it once. Every model inherits the full context.
Switch tools, and your context is stranded.
Claude remembers you inside Claude. ChatGPT inside ChatGPT. Cursor, the same. None of it travels. The gap isn't “give an AI memory” — it's give a person one memory that every AI can use, that they own.
One layer below the apps.
Not another app with memory bolted on. The memory itself — sitting beneath the tools, exposed through an open interface any client already speaks.
Connect a source
Add sources one at a time — files, mail, your public footprint. You see exactly what's readable, and nothing is grabbed wholesale. Least privilege by default.
It builds a graph
A self-maintaining temporal knowledge graph captures not just what's true, but when it became true and what superseded it. Stale facts decay on purpose — so it never rots into noise.
Every AI queries it
One MCP endpoint. Claude, Cursor, an agent fleet — they all speak the same interface and inherit your full context. Switch models, lose nothing.
A graph that maintains itself.
The substance is a living knowledge graph, not a pile of embedded files — tuned for agents that need a precise fact fast, not ten chunks to skim.
Temporal graph
Knows what's true and when it became true — and what it replaced. History, not just a snapshot.
Decay by design
Ebbinghaus-style salience fades stale facts. A memory that never forgets slowly fills with garbage — so this one forgets, on purpose.
MCP-native
A single endpoint every client already speaks. No per-tool integration, no rebuilding context per app.
Scheduled ingestion
Subagents scan connected sources, detect what's new or changed, and keep the graph current on a schedule.
Agent-tuned retrieval
Built to return the relevant thing fast — because the consumers are models that need precise context, not a human skimming results.
Audit & prune
A clean view of everything the system knows, behind your login. See it, question it, cut it. Trust you can inspect.
You decide what it knows.
“You decide what it knows” isn't a tagline — it's the architecture. Built for least privilege, not “grab everything.”
Least privilege, always
Connect sources one at a time. See exactly what each can read. Revoke it — or make it forget — on demand. Nothing is taken wholesale.
No credential storage. Ever.
We never hold a secret. If access ever needs a key, it stays in your OS keychain — not on our servers. Not in v1, not ever.
Honest about processing
When a frontier model is used, your data is processed under zero data retention and never stored on our servers. No “it never leaves your device” when it does.
