Gen Commit uses LLMs to automatically generate git commit messages. I'm lazy and don't like to write commit messages. Inspired by scommit.

gencommit works exactly like git commit, but it generates the commit message and description for you.

gencommit

is the same as

git commit -m "..." -m "..."

but with a generated commit message.

You can also pass in the same arguments as git commit.

gencommit -a

is the same as

git commit -a -m "..." -m "..."

I recommend aliasing it, personally I alias it to gc. You can do this by adding the following to your shell configuration file (.zshrc, .bashrc, etc.)

alias gc="gencommit"

brew tap raghavpillai/gen-commit
brew install gen-commit

• Python 3.11+

Install the gen-commit package using pip:

pip install gen-commit

If you get

error: externally-managed-environment

This means Python now doesn't want you to install this as a system-wide package. You can install it using pipx or venv, or be lazy and install it via:

pip3 install gen-commit --break-system-packages

Once you have it installed, initialize gencommit

gencommit --init

Go to ~/.gen-commit and add your OpenAI, Anthropic, or Google API key.

MODEL=<provider:model (i.e. openai:gpt-4.1-mini-2025-04-14, anthropic:claude-3-5-haiku-20241022, or google:gemini-2.5-flash-lite)>
OPENAI_API_KEY=<your openai api key>
ANTHROPIC_API_KEY=<your anthropic api key>
