## What it is
Codiff is a fast, minimal local diff viewer for reviewing Git changes and committing them, available as a macOS desktop app with a terminal helper command. It supports reviewing commits, branches, GitHub pull requests, and GitLab merge requests, with LLM-generated commit walkthroughs and inline review comments.

## Use cases
- review git diff locally before committing
- view changes in a git repository with a fast diff viewer
- review a github pull request locally
- review a gitlab merge request
- generate an llm walkthrough of a commit
- comment on a pull request from a local diff viewer
- compare current branch against main

## When to choose
- you want a fast, minimal native diff viewer for Git on macOS
- you review GitHub PRs or GitLab MRs locally and want to leave inline comments
- you want LLM-generated commit walkthroughs
- you prefer lightweight definition navigation without a language server

## When to avoid
- you need a cross-platform or Linux/Windows diff viewer
- you want a full Git GUI with staging, rebasing, and history management
- you need deep IDE integration or language-server-powered code intelligence
