Ask the AI — the sharing is done.

AI agents like Claude Code, Codex, and Cursor drive briefroom directly through our CLI / MCP — from upload to share URL in one step.

Three things that make briefroom different

Easy AI integration — just hand over this page's URL.

Your AI reads the integration guide and sets up the CLI / MCP connection itself. It learns how to upload and update, so all you do is give instructions.

$ npx @briefroom/cli deploy ./report

Built to be shown outside your team

Share URLs use unguessable tokens with expiry. Password protection and email allowlists (Pro), private rooms only you can open (all plans), plus a physically separated content-serving domain — a secure way to drop HTML sharing into any external review flow.

Feedback becomes the AI's next brief

Design review happens right in the browser — reviewers pick elements and leave comments. Tell your AI "pull the comments and fix them" — `feedback pull` returns them in an AI-readable format, and the fix → redeploy loop runs on a single instruction.
