What problem does it solve?

Web Cap removes the friction of browser-based agent work by giving AI a reliable way to inspect live tabs, interact with pages, and preserve successful workflows for later reuse.

Core Features & Use Cases

  • Live Browser Control: Click, type, read page state, and navigate real Chromium tabs through a local runtime.
  • Reusable Workflows: Save repeatable browser tasks as capability scripts and run them again on demand.
  • Persistent Page Automation: Create AI-native userscripts for page-specific behavior that should run automatically on matching sites.
  • Use Case: An agent can summarize a page, extract structured data from a dashboard, or automate a multi-step website workflow without relying on fragile screen scraping alone.

Quick Start

Use the web-cap skill to install the web-capability CLI, connect the browser extension, and verify the session with a browser automation task on the active tab.

FAQPage Schema
How do I automate browser tab interactions from an AI agent?

To automate browser tab interactions from an AI agent, you use a local-first CLI to inspect live Chromium tabs, click, type, and read page state directly. This approach removes fragile screen scraping by connecting the agent to a real browser runtime.

How do I save and reuse browser automation scripts for repeatable workflows?

You can save repeatable browser tasks as reusable capability scripts and run them on demand. This allows you to execute one-off actions via script-execute or create AI-native userscripts for page-specific behavior that runs automatically on matching sites.

Do I need a browser extension to control live tabs with a CLI?

Yes, controlling live tabs with this CLI requires a connected browser extension runtime. You must connect the extension and verify the session status to enable the agent workflow to interact with real browser tabs.

What is the best way to extract structured data from a live web page using AI?

The best way to extract structured data from a live web page is by inspecting active browser tabs and reading page state through a local CLI. This method enables agents to summarize pages and pull data directly from dashboards without relying solely on screen scraping.

Can I automate multi-step website workflows with Playwright and reusable scripts?

Yes, you can automate multi-step website workflows by creating AI-native userscripts and reusable capability scripts. These scripts interact with real Chromium tabs to perform complex sequences of actions and navigate pages reliably.

Why does my agent fail to select the correct browser tab during automation?

Agent browser tab selection fails if the session-status is not properly verified or the browser extension runtime is disconnected. You must ensure the local CLI is connected to the extension and actively select the target tab before executing scripts.
