gptcommit
Never write a commit message again: git hook that drafts messages with an LLM.
About
gptcommit by zurawiki is a git prepare-commit-msg hook that uses a large language model to draft commit messages from your staged diff. Run git commit as usual and the hook fills in a message — a short imperative title plus one to three factual bullets with conventional-commit prefixes — which you can edit before committing. It is written in Rust, distributed via crates.io and Homebrew.
Install with cargo install --locked gptcommit, then gptcommit install in each repo with an OpenAI API key. Recent versions default to a fast reasoning model (gpt-6-luna) with per-file summaries, quiet generation, and configurable ignore rules, and empty or fully ignored staged changes leave the message untouched. It remains one of the most-starred AI commit-message tools in the Rust CLI space.
What it can do
- Auto-drafts commit messages from staged diffs via a git hook
