All three write your commit messages with AI — and they're good at it. That part is table stakes now. The real question is what you want around the commit. OpenCommit and aicommits are focused, single-purpose tools. git-coco is an AI git toolbelt: commits, changelogs, review, and PR/MR creation, in a terminal workstation that works on GitHub and GitLab.

Comparison reflects each tool's primary, documented CLI as of June 2026. Tools evolve quickly — corrections welcome via an issue.
They aim at different things. Here's the honest version.
You want the absolute simplest thing: a tiny, focused CLI / git hook that writes a commit message and nothing else. Minimalism is the point.
You want a popular, well-supported commit-message tool with emoji and a GitHub Action, and you live on GitHub. It does its one job well.
You want AI across the whole workflow — commits, changelogs, review, PR/MR — in one tool, a keyboard-driven workstation to run it from, and/or you're on GitLab or GitHub Enterprise. Breadth and multi-forge are the point.
One command installs and configures everything — pick a provider (including local Ollama) and go.
