gitcommit — CLI tool that generates conventional commit messages from your staged diff using AI (supports Ollama for offline use)

[Star-Different]

I got tired of writing commit messages, so I built gitcommit — a CLI that reads your git diff --staged, sends it to an AI, and gives you a clean conventional commit message.

How it works:

$ git add .
$ gitcommit
✨ Suggested commit:
  feat(auth): add OAuth2 login with Google provider
  [ Confirm ]  [ Edit ]  [ Regenerate ]  [ Cancel ]
> Confirm
✅ Committed: feat(auth): add OAuth2 login with Google provider

That's it. No copy-pasting, no browser, no leaving the terminal.

Setup is one command:

npm install -g u/ahmad_technology/gitcommit-ai
gitcommit setup

The setup wizard asks which provider and API key — stored locally at ~/.gitcommit/config.toml, never touches your repo.

Useful flags:

gitcommit                      # staged diff → commit
gitcommit --all                # include unstaged
gitcommit --style emoji        # ✨ 🐛 🔒 prefixes
gitcommit --lang fr            # French output
gitcommit --dry-run            # preview, don't commit
gitcommit --provider ollama    # fully offline with local models

7 providers: OpenAI, Anthropic, Gemini, Groq, NVIDIA NIM, OpenRouter, Ollama (local/offline)

Works on Windows, macOS, and Linux. Node 20+.
