Threads
Spaces of markdown threads with comments, @mentions and attachments. Each thread carries an AI-written summary head — topic, conclusion, what it's waiting on, where the room diverges — so a long thread can be read in four lines.
Team workspace
A team workspace where AI works on the same content you do.
Stele keeps a team's written record in one place: spaces of markdown threads, a file tree per workspace, and an AI chat whose agent reads and writes through the same content over MCP. No exports, no separate index, no second copy of the truth.
Files
A file tree per workspace, backed by object storage and bound to the spaces that use it. Attachments on a thread and documents in the tree are the same kind of thing, addressed the same way.
Chat
An AI chat that reaches threads, comments and files through MCP — the same permissions your account has, nothing more. Publish an agent, connect a local one, or schedule a run against the workspace.
