Gemini Commit Message

Generate concise Git commit messages from your changes using Google Gemini.

This extension analyzes your Git changes and generates a commit message directly in the Source Control input box, keeping commits consistent, readable, and fast without leaving VS Code.

Features

• Generate commit messages from staged changes
• Falls back to unstaged changes when nothing is staged
• Handles new repositories safely
• Writes natural-language sentences in lowercase while preserving original casing for variable names, constants, and file names
• Uses Google Gemini (2.0 Flash) for fast generation
• Cancellable loader with clean error handling
• Cross-platform support (macOS, Windows, Linux)

How it works

1. If staged changes exist, they are used
2. Otherwise:
   • Existing repo: unstaged diff
   • New repo: file change summary
3. The changes are sent to Gemini
4. The generated message is inserted into the Git commit input box

Requirements

• Git installed and available in PATH
• A Google Gemini API key

Setup

1. Get a Gemini API key

1. Go to https://ai.google.dev/

Rate limits

This extension uses the Google Gemini API.

Usage may be subject to API rate limits, especially on the free tier. If a limit is reached, a friendly message will be shown.

Enabling billing in Google AI Studio increases available limits.

Privacy

• Your code is sent only to Google Gemini to generate the commit message
• No data is stored or logged by this extension
• API keys are stored locally in VS Code settings

Known limitations

• Large diffs may be summarized or truncated
• Free-tier quotas may be exhausted during heavy testing
• Multi-root workspaces use the first repository only
