Pi App

A desktop app for the pi coding agent.
The same agent and the same ~/.pi/agent you use in the terminal — with a timeline, Git review and a clickable session tree.

pi Desktop is not another agent. It runs the pi SDK in a background worker and reads the same files as the CLI — sessions, model logins, settings.json, installed extensions. Open a project and the sessions you started in the terminal are already in the sidebar; continue any of them, or start a new one.

At a glance

One turn, start to finish

_{Recorded from the app itself. The model replies come from a scripted local endpoint so the demo is reproducible; the bash, read and edit tools ran for real on the sample repo.}

Timeline

Tool calls stream in as flat steps — thinking, commands, reads, edits — and fold into one summary line once the answer starts. Each edit shows +N −M; the turn ends with a Files changed card that opens the file in Files or Review.

Markdown, code blocks, KaTeX and long outputs render in place. Hover a message to copy it, rewind to it, or fork a new session from it.

Review

Pick a scope — this turn, this session, or the whole Git working tree — and expand a file for its diff; drag the sidebar wider for a side-by-side view. Hunks can be staged or unstaged one at a time, and a line comment goes straight back into the conversation.

Files

• Browse the project next to the chat; Ctrl/⌘+click opens a file in another tab.
• The gutter button quotes path:line into the composer as a reference.
• Expand preview gives the file the whole chat column; click again to go back. Drag a file onto the composer to attach it.
