✨ gitc - AI-Powered Git Commit Messages

Installation • Features • Configuration • Usage • Full Options • AI Providers

gitc is a fast, lightweight CLI tool that uses AI to generate clear, consistent, and standards-compliant commit messages — directly from your Git diffs. With built-in support for Conventional Commits, Gitmoji, and fully customizable rules, gitc helps you and your team write better commits, faster

🚀 Features

gitc streamlines your Git workflow by automating professional commit message creation with AI. Its robust feature set ensures flexibility and precision for developers and teams.

• 🧠 AI and Commit Generation

  • AI-Powered Commit Messages: Generates high-quality commit messages using OpenAI's API, analyzing staged git changes for context-aware results.
  • Multilingual Support: Creates commit messages in multiple languages (e.g., English, Persian, Russian) to suit global teams.
  • Extensible AI Providers: Supports OpenAI with plans for Anthropic and other providers, ensuring future-proofing.

• 📝 Commit Standards and Customization

  • Conventional Commits: Adheres to standard commit types (feat, fix, docs, style, refactor, test, chore, build, ci, revert, init, security) for semantic versioning.
  • Gitmoji Integration: Optionally adds Gitmoji emojis (e.g., ✨ for feat, 🚑 for fix) for visually appealing commits.
  • Custom Commit Conventions: Supports JSON-based custom prefixes (e.g., JIRA ticket IDs) for tailored commit formats.

• 🔧 Git Integration

  • Optimized Git Diff Processing: Automatically retrieves and filters staged git diff, excluding irrelevant files (e.g., node_modules/*, *.lock).
  • Configurable Exclusions: Customize file exclusion patterns via config file to focus on relevant changes.

• ⚙️ Environment & Configuration

  • Flexible Configuration: Customize via CLI flags, environment variables, or a JSON config file (~/.gitc/config.json).
  • Proxy Support: Configurable proxy settings for API requests in restricted environments.
  • Timeout and Redirect Control: Adjustable timeouts and HTTP redirect limits for reliable API interactions.
  • Environment Variable Support: Simplifies setup for sensitive data (e.g., API keys) and common settings.

• ⚡️ Performance & Reliability

  • Fast Processing: Leverages sonic for rapid JSON parsing and fasthttp for efficient HTTP requests.
  • Error Handling: Robust validation and error messages ensure reliable operation.

📚 Full Options

The following CLI flags are available for the ai-commit command and its config subcommand. All flags can also be set via environment variables or the ~/.gitc/config.json file.

Flag	Alias	Description	Default	Environment Variable	Example
--all	-a	Stage all changes before generating commit message (equivalent to git add .)	false	GITC_STAGE_ALL	-all or -a
--provider	-	AI provider to use (e.g., openai, anthropic)	openai	AI_PROVIDER	--provider openai
--url	-u	Custom API URL for the AI provider	Provider-specific	GITC_API_URL	--url https://api.x.ai/v1/chat/completions
--model	-	OpenAI model for commit message generation	gpt-4o-mini	-	--model gpt-4o
--lang	-	Language for commit messages (e.g., en, fa, ru)	en	GITC_LANGUAGE	--lang fa
--timeout	-	Request timeout in seconds	10	-	--timeout 15
--maxLength	-	Maximum length of the commit message	200	-	--maxLength 150
--api-key	-k	API key for the AI provider	-	AI_API_KEY	--api-key sk-xxx
--proxy	-p	Proxy URL for API requests	-	GITC_PROXY	--proxy http://proxy.example.com:8080
--commit-type	-t	Commit type for Conventional Commits (e.g., feat, fix)	-	GITC_COMMIT_TYPE	--commit-type feat
--custom-convention	-C	Custom commit message convention (JSON format)	-	GITC_CUSTOM_CONVENTION	--custom-convention '{"prefix": "JIRA-123"}'
--emoji	-g	Add Gitmoji to the commit message	false	GITC_GITMOJI	--emoji
--no-emoji	-	Disables Gitmoji in commit messages (overrides --emoji and config file)	false	-	--no-emoji
--max-redirects	-r	Maximum number of HTTP redirects	5	GITC_MAX_REDIRECTS	--max-redirects 10
--config	-c	Path to the configuration file	~/.gitc/config.json	GITC_CONFIG_PATH	--config ./my-config.json

Note

• Flags for the config subcommand are similar but exclude defaults, as they override the config file.
• Flags > Environment Variables > Config File — This is the order of precedence when multiple settings are provided.
• The --custom-convention flag expects a JSON string with a prefix field (e.g., {"prefix": "JIRA-123"}).
• The --version flag displays the current tool version (e.g., 0.2.0) and can be used to verify installation.
• The --all flag (alias -a) stages all changes in the working directory before generating the commit message, streamlining the workflow. For example, gitc -a --emoji stages all changes and generates a commit message with Gitmoji.
• Environment variables take precedence over config file settings but are overridden by CLI flags.
• You can reset all configuration values to their defaults by using gitc config gitc reset-config.

🤖 AI Providers

gitc is designed to be AI-provider agnostic. While it currently supports OpenAI out of the box, support for additional providers is on the roadmap to ensure flexibility and future-proofing.

Provider	Supported Models	Required Configuration	Status
OpenAI	gpt-4o, gpt-4o-mini, gpt-3.5-turbo	api_key, model, url (optional)	✅ Supported (default)
Grok (xAI)	grok-3 (experimental)	api_key, model, url	🧪 Experimental Support
DeepSeek	deepseek-rag (experimental)	api_key, model, url	🧪 Experimental Support
Gemini (Google)	Coming Soon	-	🔜 Planned
Others	-	-	🧪 Under consideration

ℹ️ We're actively working on supporting multiple AI backends to give you more control, flexibility, and performance. Have a provider you'd like to see? Open a discussion!
