briefroom is an HTML sharing service that lets AI coding agents publish HTML they generate directly from the agent, creating a feedback loop of client review, comment collection and HTML updates. It works with Claude Code, Codex, Cursor and similar tools through an MCP server or a CLI.
The service serves user HTML from a separated domain, lets clients tap an element in the browser to post a comment, and notifies the owner by email, while a CLI pulls LLM-ready Markdown comments back. Two integration paths, an MCP server for native tool calls and a CLI, perform the same operations. A shared link can carry expiry and password protection, and teams can manage access by email invite.
briefroom keeps every core feature free. The Founders Edition is a one-time ¥4,800 that unlocks every Pro feature, and the Pro plan is ¥690 /mo for individual professionals with more shared rooms and share URLs.
