## What it is
gptcommit is a git prepare-commit-msg hook written in Rust that uses large language models like GPT to automatically generate clear, descriptive commit messages. It installs via cargo or homebrew and integrates directly into the normal `git commit` workflow.

## Use cases
- automatically generate commit messages with GPT
- never write commit messages manually again
- summarize git diffs into commit messages using an LLM
- install a prepare-commit-msg hook powered by OpenAI
- use AI to author descriptive git commit messages
- speed up committing by letting an LLM draft the message

## When to choose
- you want AI-generated commit messages integrated directly into your git workflow
- you use OpenAI models and want a fast, Rust-based hook
- you want configurable per-repo or global settings for commit message generation

## When to avoid
- you don't want to send your code diffs to a third-party LLM API
- you need fully offline commit message generation
- you don't use git or don't want hooks modifying your commit flow
