Generate Conventional Commit messages with AI. The downloaded script sends your Git diff directly to OpenRouter; API keys and diffs do not pass through commit.jaw.dev.

Open commit.jaw.dev in a browser to view the usage guide. Requests made with curl continue to return the commit script.

Ensure you have tr, jq, git, tail, sed, and curl installed on your system. Most developers will already have these tools, but if you need to install them, use the following commands for your operating system:

# macOS
$ brew install jq git curl coreutils gnu-sed

# Linux (Debian-based)
$ sudo apt-get install jq git curl coreutils sed

# Linux (Red Hat-based)
$ sudo dnf install jq git curl coreutils sed

# Linux (Arch-based)
$ sudo pacman -S jq git curl coreutils sed

Or if you already have curl you can run the following script to detect OS and install it automatically.

$ curl -fsSL https://commit.jaw.dev/install.sh | bash

On the first run, Commit asks for your OpenRouter API key and preferred model. It uses openrouter/free when you press Enter at the model prompt, then creates ~/.config/commit/config.json with private permissions automatically:

$ git add .
$ curl -fsSL https://commit.jaw.dev/ | bash

The generated configuration looks like this:

{
  "api_key": "YOUR_OPENROUTER_API_KEY",
  "model": "openrouter/free"
}

Create an API key at openrouter.ai/keys. Run setup again at any time:

$ curl -fsSL https://commit.jaw.dev/ | bash -s -- --setup

Set OPENROUTER_API_KEY to avoid saving a key locally. --model overrides COMMIT_MODEL, which overrides the model saved in the configuration. Browse valid model IDs at openrouter.ai/models, or list them from the API:

$ curl -fsSL https://openrouter.ai/api/v1/models | jq -r '.data[].id'

After setup, stage changes and run the normal command:

$ curl -fsSL https://commit.jaw.dev/ | bash

• -m, --model Override the configured OpenRouter model for one run
• --dry-run Run the script without making any changes
• -y, --yes Accept the generated message without confirmation
• -v, --verbose Enable verbose logging
• --setup Configure the saved API key and model
• -h, --help Display this help message

$ curl -fsSL https://commit.jaw.dev/ | bash -s -- --yes
$ curl -fsSL https://commit.jaw.dev/ | bash -s -- --dry-run
$ curl -fsSL https://commit.jaw.dev/ | bash -s -- --model openrouter/auto
$ curl -fsSL https://commit.jaw.dev/ | bash -s -- -v
$ curl -fsSL https://commit.jaw.dev/ | bash -s -- -h
$ curl -fsSL https://commit.jaw.dev/ | bash

The configuration path follows $XDG_CONFIG_HOME when set and defaults to ~/.config/commit/config.json. Set COMMIT_CONFIG to use another path. The default model is openrouter/free, which randomly selects an available free model. Free models have lower rate limits and may be less consistent. Pass a model ID exactly as OpenRouter displays it, for example openrouter/auto, to override the default. Model IDs must not contain whitespace. Diffs larger than 1 MiB are rejected before an API request is made.
