Overview

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.
