Windows and projects

A project is a folder you work in. Tyrn shows projects in a sidebar docked on the left, and each project can be open in one window.

Open a project

Click + next to Projects in the sidebar (“Open project”) and choose a folder.

A project is open in at most one window. If you add one that is already open in another window, Tyrn focuses that window instead.

Under each project:

Agents: running sessions, or “No running agents”.
History: past conversations. Use Show more for older ones.
Worktrees, in Git projects, with a New worktree (+) button. See Run sessions in parallel.

Open in New Window
Remove from Window: detaches the project from this window only. It deletes nothing.
Reveal in Finder

Windows and sessions

Closing a window doesn’t stop its sessions. They run in the Tyrn backend, and you can attach again from any window that has the project open. See Resume a session.
