Exposes live browser tabs as Markdown files so AI agents can read web content with filesystem tools and trigger Chromium actions by appending commands, with diffs showing changes.
preprint is a command-line tool that projects open Chromium tabs into Markdown files for AI agents. It runs a background daemon, writes each tab’s page state and accessibility information to files, and accepts browser actions appended beneath a marker in those files. The tool also maintains tab listings and diffs, captures console output and exceptions, and can save screenshots and recordings. It supports named browser sessions and Chrome profiles, and includes an agent-browser skill for compatible coding agents.
The repository says it vendors patches against upstream agent-browser and launches it to control Chromium via CDP.
