What it does
OpenCLI is a browser automation tool for AI agents. It connects to your Chrome browser through an extension, so an agent can open pages, click, fill in forms, read content and take screenshots, using the accounts you are already signed in to.
It also includes ready-made "adapters" for sites such as Reddit, Hacker News, X and several Chinese platforms. These turn common actions on a site into simple, repeatable commands.
You can add it as a skill to coding agents like Claude Code or Cursor, and there are tools to help you write new adapters.
Who it's for
