• Anthropic • Cerebras • Chutes.ai • DeepSeek • Fireworks
• Gemini • Groq • LM Studio • MiniMax • Mistral • Ollama • OpenAI
• OpenRouter • Streamlake • Synthetic.new • Together AI
• Z.AI • Z.AI Coding • Custom Endpoints (Anthropic/OpenAI)

• Understands intent: Analyzes code structure, logic, and patterns to understand the "why" behind your changes, not just what changed
• Semantic awareness: Recognizes refactoring, bug fixes, features, and breaking changes to generate contextually appropriate messages
• Intelligent filtering: Prioritizes meaningful changes while ignoring generated files, dependencies, and artifacts
• Intelligent commit grouping - Automatically group related changes into multiple logical commits with --group

• One-liner (-o flag): Single-line commit message following conventional commit format
• Standard (default): Summary with bullet points explaining implementation details
• Verbose (-v flag): Comprehensive explanations including motivation, technical approach, and impact analysis

• 25+ languages: Generate commit messages in English, Chinese, Japanese, Korean, Spanish, French, German, and 20+ more languages
• Flexible translation: Choose to keep conventional commit prefixes in English for tool compatibility, or fully translate them
• Multiple workflows: Set a default language with gac language, or use -l <language> flag for one-time overrides
• Native script support: Full support for non-Latin scripts including CJK, Cyrillic, Arabic, and more

• Interactive feedback: Type r to reroll, e to edit in-place with vi/emacs keybindings, or directly type your feedback like make it shorter or focus on the bug fix
• One-command workflows: Complete workflows with flags like gac -ayp (stage all, auto-confirm, push)
• Git integration: Respects pre-commit and lefthook hooks, running them before expensive LLM operations

• Automatic secret detection: Scans for API keys, passwords, and tokens before committing
• Interactive protection: Prompts before committing potentially sensitive data with clear remediation options
• Smart filtering: Ignores example files, template files, and placeholder text to reduce false positives

# Stage your changes
git add .

# Generate and commit with LLM
gac

# Review → y (commit) | n (cancel) | r (reroll) | e (edit) | or type feedback

# Complete workflow in one command
gac -ayp -h "release preparation"

# Detailed explanation with scope
gac -v -s

# Quick one-liner for small changes
gac -o

# Group changes into logically related commits
gac -ag

# Debug what the LLM sees
gac --show-prompt

# Skip security scan (use carefully)
gac --skip-secret-scan

Not happy with the result? You have several options:

# Simple reroll (no feedback)
r

# Edit in-place with rich terminal editing
e
# Uses prompt_toolkit for multi-line editing with vi/emacs keybindings
# Press Esc+Enter or Ctrl+S to submit, Ctrl+C to cancel

# Or just type your feedback directly!
make it shorter and focus on the performance improvement
use conventional commit format with scope
explain the security implications

# Press Enter on empty input to see the prompt again

The edit feature (e) provides rich in-place terminal editing, allowing you to:

• Edit naturally: Multi-line editing with familiar vi/emacs key bindings
• Make quick fixes: Correct typos, adjust wording, or refine formatting
• Add details: Include information the LLM might have missed
• Restructure: Reorganize bullet points or change the message structure

Run gac init to configure your provider interactively, or set environment variables:

Need to change providers or models later without touching language settings? Use gac model for a streamlined flow that skips the language prompts.

# Example configuration
GAC_MODEL=anthropic:your-model-name
OPENAI_API_KEY=your_key_here
ANTHROPIC_API_KEY=your_key_here

See .gac.env.example for all available options.

Want commit messages in another language? Run gac language to select from 25+ languages including Español, Français, 日本語, and more.
