GitHub Copilot app for Beginners: Using the diff, terminal, and browser

The guide shows how to view diffs, run terminal commands, and preview web apps side by side in the GitHub Copilot app.
Engineers often switch between separate tabs to review code, run commands, and test web output, which slows feedback loops. By consolidating these actions inside the Copilot app, the workflow becomes more continuous, letting developers stay focused on the code they are evaluating.

The Copilot app now lets users view code diffs alongside the editor.
It includes an embedded terminal for executing commands without leaving the app.
It provides an embedded browser preview for web apps, enabling side-by-side testing.
THE READ
What the cluster adds up to.
GitHub has added integrated panels to the Copilot app that display a diff view, a terminal, and a browser preview within the same window. The headline and summary indicate that these panels can be arranged side by side, allowing a single interface to handle code inspection, command execution, and web-app rendering. This change expands the Copilot app from a pure code-completion tool to a lightweight development environment.
For engineers, the main benefit is reduced context switching. The summary notes that checking agent-generated code usually requires hopping between tabs; with the new panels, the same tasks can be performed in one place. This can shorten the feedback cycle when reviewing AI-suggested changes, especially for web projects that need immediate visual verification.
Adopting the new layout incurs little direct cost: the guide is aimed at beginners and does not mention any additional licensing or configuration steps. The only requirement is to use the Copilot app itself rather than external editors or terminals for the illustrated tasks. Consequently, teams can try the feature without changing existing toolchains, though they may still need separate tools for more advanced debugging or multi-repo workflows.
The guide’s focus on side-by-side usage implies that the integrated views are best suited for relatively simple scenarios, single-file diffs, straightforward terminal commands, and basic web previews. Complex build pipelines, language-specific debugging, or non-web applications are not covered, so engineers should treat the feature as a convenience layer rather than a full replacement for a dedicated IDE or terminal environment.
