Description
When users do not know how, they stall or leave. ActBrow finishes the task inside your product: they ask in plain English, it navigates to the right screen, calls your APIs, and the work is done.
About ActBrow
What is ActBrow?
ActBrow is an embedded AI agent runtime that lets users navigate a web app, call its APIs, run workflows, and ask questions from documentation.
What ActBrow does
It adds an in-product chat widget to an existing app without a backend rewrite. Registered tools execute through REST, and navigation can move the user to the relevant screen. A hosted early-access option and a self-hosted Docker stack provide different deployment choices.
Who ActBrow is for
It is for teams adding a task-performing assistant to their web product, with framework examples for React and Vue and an embed for plain HTML.
How ActBrow works
Teams create an assistant in the dashboard and use its identifier and key in the widget configuration. A coding-agent setup prompt can synchronize tools and documentation. They add the SDK and widget scripts before the closing body tag, then return client-tool execution results over REST.

- The widget accepts plain-English task requests.

- Flows combine navigation and tool calls.
- Documentation supplies answers within the app.
