I built git-ai – generate Conventional Commit messages via Claude/Copilot/Codex CLI

I built a small cli called git-ai that adds a git ai commit command to your workflow.
It reads git diff --staged, sends the diff to your preferred AI CLI (Claude, GitHub Copilot, or OpenAI Codex), and generates a Conventional Commit message automatically. A spinner animation shows the progress, and if one model isn't installed or fails, it silently falls back to the next available one.

$ git add .
$ git ai commit
⠹ Generating commit message with copilot...
✅ Generated by copilot

Proposed: feat: add user authentication middleware

Features:

Supports Claude CLI, GitHub Copilot CLI, and OpenAI Codex CLI
Auto-detects which model to use (claude → copilot → codex)
--edit / -e flag to review and modify in vi before committing
Pure bash, no dependencies beyond the AI CLI itself
One-line install via install.sh

The motivation was simple: I kept writing the same kinds of commit messages over and over. With git-ai, I just stage my changes and let the AI handle the wording — it's surprisingly good at following Conventional Commits format.
