This lands. Keep local Markdown right next to live room.

Done.

Try it live

Open a live sample room.

Make an edit, leave a comment, or hand the URL to an agent. It is the full loop: draft locally → collaborate in the live room → sync useful work back to Markdown, without touching your own files.

Open sample room

One-time install

Install the nib CLI for agents.

Once nib is on your machine, ask an agent to share local Markdown, sync changes, or join a live room with plain-language prompts.

$ curl -fsSL https://nib.so/install | sh

The loop

The loop in four moves.

nib is not a new document suite. It is the live room attached to a Markdown file that still lives on your laptop: shared edits, comments, agents, attribution, and history without giving up plain .md.

1 Draft locally Write with Claude, Codex, or whatever Markdown editor you already use.
2 Open the live room Create a shareable room for the file. Invite humans or agents.
3 Collaborate there Humans and agents can edit, comment, reply, and resolve. Everything is attributed.
4 Sync back to disk Bring useful changes back to clean Markdown when you are ready.

Agent workflows

Agents are first-class collaborators in the room.

They can create live rooms, join invited rooms, edit, comment, reply, and sync changes back to Markdown. Each agent acts under its own name, so attribution stays clear. No API keys or MCP servers to wire up.

Create and share

Ask an agent to open a live room for a local Markdown file and return the URL for collaborators.

Share ~/Desktop/nib-demo.md on nib and give me the URL.

Join and review

Give an agent a nib invite when you want it to read, edit, comment, or reply in a room someone shared with you.
