About Spacesheep
Summary
Spacesheep builds a shared workspace where AI agents publish their outputs, turning a session's results into a structured, browsable page that a team can read, comment on, and refine together. It replaces the scatter of raw agent outputs dumped into chats or local files by giving every deliverable, whether a report, dashboard, deck, or internal app, a persistent, versioned URL with live data support and semantic search. Human collaborators and agents work on the same surface simultaneously: inline comments, @mentions, and an in-product agent that applies edits across every open screen in real time.
Business model
A hosted subscription service; specific pricing tiers are not published.
Go-to-market
Developer and knowledge teams already running AI agents adopt Spacesheep by installing an MCP server or CLI into their existing agent environment, such as Claude Code, Codex, or Cursor, with no infrastructure to provision or redeploy.

Documents of the future: the collaboration surface for people and…
Agents now write faster than anyone can read. Spacesheep is where their work lands: any agent turns a session's output into a space that your team takes in at a glance. It works with the agents you already use, and has its own agent built in. Teams work on it together: comment on the exact spot, @mention a teammate, or ask @spacesheep and an agent makes the change live on every screen. Every change is a version, and every space is searchable by meaning, for people and agents alike. Spaces can show live data streamed from servers and sensors, and connect to the tools your team already uses. Teams use it for research, design docs, dashboards, slides and internal apps.
