What is codiff?

Codiff is a desktop application for reviewing changes in a Git repository before you commit them. Instead of reading a diff in the terminal or scrolling through a web based pull request page, Codiff opens a clean local window that shows your staged and unstaged changes in a minimal, easy to scan layout. Beyond a plain diff view, Codiff adds a few review focused features. You can leave inline comments directly on specific changed lines, then copy every comment you left as Markdown text, useful for pasting into a commit message, a pull request description, or a follow up task list. There is also an LLM powered walkthrough mode, started with the codiff -w command, which asks Codex to suggest a sensible order to review the changed files in and add extra context about what changed. You install Codiff as a downloadable desktop app from the project's GitHub Releases page. Once installed, running an in app command called Install Terminal Helper adds a codiff command to your shell, so from then on you can type codiff inside any Git repository to open that repository's changes in the app, or pass a specific folder path to open a different repository. Opening Codiff for several repositories at once creates a separate window for each one. Codiff is built with TypeScript and Electron, and its build tooling uses a set of internal commands, vp and vpr, for installing dependencies, building the app, running checks and tests, and starting a live development server. The README does not mention what license the project is released under.
