GitHub Copilot app adds diff, terminal, browser panels
GitHub’s Copilot app now bundles diff, terminal, and browser panels so developers can review, run, and preview AI‑generated changes without leaving the interface.

The GitHub Copilot app has introduced three built‑in panels—a diff view, a terminal, and a browser—allowing users to stay inside the app while completing the AI coding loop. The diff panel displays line‑by‑line additions and deletions, letting users accept, comment on, or request further changes from the agent. The terminal panel lets developers execute project commands directly, including running scripts via a Run button and opening multiple terminal windows. The browser panel provides an in‑app preview of UI changes, with a Pick & Polish tool for selecting and adjusting elements.
By keeping review, execution, and preview side by side, the app aims to make agent‑generated code feel safer for beginners, helping them answer what changed, whether it runs, and if it works before merging.
