Free for you. Paid when you scale.
Personal use is free and unlimited, and includes three agent subscriptions — every model call runs on your side of the bill, through the client you already pay for or the API key you add in Settings, so there is nothing for us to meter. You pay per seat for unlimited agents and for sharing a memory with someone else.

A personal account is free at any size and comes with three agent subscriptions. The paid plan starts when you want more agents or invite another person into a memory — and a seat is an active user, so the price never moves with how much graph you build.
The extraction runs on your side of the wire.
Ontonym hands your AI client a prompt and stores what comes back — and background automations run on the key you bring. That one decision removes our usage bill entirely, and means your documents are processed by the model you already trust, not one we picked.
Your model, your bill
Connect Claude, Cursor or any MCP client. It fetches the extraction prompt, runs it on the model you already pay for, and sends the structured result back — the model call never lands on our bill.
Automations, your key
Connector syncs, scheduled crawls, inbound email and agents run in the background on the API key you add in Settings. Your provider bills you directly — we never mark it up.
Agents & sharing are the product
A memory of your own is free at any size, with three agent subscriptions included. What the paid plan buys is unlimited agents and other people: organizations, per-memory roles, and approving who gets into a private memory.
Run it entirely on your own infrastructure.
For teams that can't send data outside their walls, Ontonym installs on-site or in your cloud VPC — your data never leaves your VPC. Ask price: billing is arranged per agreement, not per seat.
On-site & cloud VPC installation
Run the whole stack inside your own environment — on your own hardware or in your cloud VPC. The graph, the extraction, and the model traffic never leave your VPC.
SSO / SAML
Bring your own identity provider and provision members through it.
Row-level access controls
Every object and property carries access grants; replies are filtered to each viewer's permissions.
Audit logging
A full trail of what was read, approved, and changed — exportable for compliance.
