aicommit

AI-powered commit message generator following the Conventional Commits spec. Analyzes your staged git diff and suggests a ready-to-use commit message, which you confirm before committing.

Supports Anthropic, OpenAI, and Ollama (runs locally, no API key needed).

Why use it

There are similar tools out there (opencommit, aicommits), but aicommit focuses on:

• Native support for 3 providers, including Ollama for anyone who doesn't want to depend on a paid API.
• Commit messages generated in whatever language you configure.
• Interactive confirmation before committing (the AI suggests, you decide).

Installation

npm install -g @smeltier/aicommit

Setup

1. Choose a provider and configure it

Anthropic or OpenAI (equires an API key):

export AICOMMIT_PROVIDER=anthropic   # or openai
export AICOMMIT_API_KEY=your-api-key

Ollama (runs locally, no API key needed):

export AICOMMIT_PROVIDER=ollama

Make sure you have Ollama installed and running (ollama serve), with the model pulled (ollama pull llama3).

2. (Optional) Commit message language

export AICOMMIT_LANG=en   # default: en

3. Persist the variables

Add the lines above to your .zshrc or .bashrc so you don't have to set them every time:

echo 'export AICOMMIT_PROVIDER=anthropic' >> ~/.zshrc
echo 'export AICOMMIT_API_KEY=your-api-key' >> ~/.zshrc

Then reload your shell (source ~/.zshrc) or open a new terminal.

Usage

git add .
aicommit

aicommit shows the suggested message and asks for confirmation before committing:

Commit message: feat(auth): add token refresh logic

Confirm? (Y/n)
