Open protocol · Agent-neutral

Let agents drive your apps — in the open.

App Use is an open protocol that turns any application into an agent-drivable surface. The app declares what it can do; the agent reads and acts through a single protocol. Every action is observable, recorded in a tamper-evident audit trail, and dangerous steps stop for human approval.

THE PROBLEM

Today, you can't see what the agent is doing

Agents drive software two ways today — and both leave you in the dark.

CLI / API adapters

The agent shells out to a per-app command line. You approve opaque text in a terminal and hope it matches what actually happens. Every new app needs a new adapter.

Screen-scraping / vision

The agent clicks around from screenshots. It's brittle, slow, and bypasses every accessibility and consent gate your OS already has.

App Use — the third path

The app participates. It declares its screens, elements, and actions through an open protocol, and the agent reads from and writes to it directly. You see exactly which app and which feature the agent is operating — and you hold the approval button on anything risky.

WHAT APP USE IS

One protocol, three parts

The Protocol

Open · Free · Public

The open standard: the AppSpec model, the app.* tool vocabulary, capability scopes, the consent gate, and the audit chain. Published for the whole industry to adopt.
