Protocollum ex ipsa applicatione
Protocolis gives AI agents typed operations to call on web applications they have never seen, and checks every result. No site-specific setup. No screenshots. Secrets never enter the agent's context.

Browser Use has two modes: a default agent that reads a screenshot every step, and a tools mode for tool-calling models. Protocolis costs less than either on every model we have measured, and does ten things neither mode does.

Protocolis against Browser Use on live websites: paired runs, the same model and the same tasks for both. Held-out tasks are Online-Mind2Web tasks never used in development. Cost is estimated at each provider's cached list prices. Browser Use 0.13.10 (default agent) and 0.13.13 (tools mode); its capabilities are taken from its published source code, version 0.13.13. Full results, build hashes and the reproduction kit are available under NDA.
On first contact, Protocolis compiles the application into operations an agent can call. No adapter is written and no workflow is taught.
The agent calls typed operations: search, filter, fill, select, submit. It reasons about the task, not about pixels or page structure.
Every operation reports what was done and what remains unproven. Passwords and keys are handled by a credential broker and never enter the model's context.
Recorded against Browser Use's default agent on GLM-5.3-flash, with the same task and the same budget for both.
Protocolis is the work of a sole inventor. It is operational, pre-revenue and patent pending. The engine, the credential broker, the measurement record and the reproduction kit are offered together, with a transition period and, if the acquirer wants one, a continuing role.
A recorded demonstration and a live screen share.
Under NDA, your engineers run their own agents and tasks on a hosted instance.
At letter of intent, a time-limited build for inspection.
