Put your context to work.
We're building LockN to connect what you know with what you want to do, through personal AI and the infrastructure behind it.

Start with your context.
Your knowledge, priorities, and work already underway.
-
Choose your models.
Intelligence suited to the task, with choice over how it’s used.

Meet the founderHow LockN works
- Private and persistent
- Your context stays yours and carries over from one task to the next.
- Permissioned and provider-neutral
- You decide what an agent may do, and which models it may use.
- Personalized and self-hostable
- LockN adapts to how you work, and can run on infrastructure you control.
- With receipts
- A receipt records an observation, operation, or judgment. It helps you inspect what happened; it does not establish that a claim is true or that an action was approved.
