# git commit-at

**AI-powered git commit message generator** — local, private, no API key needed.

`git commit-at` analyzes your staged changes and suggests 3 conventional commit messages
using a locally-running AI model (Ollama). Pick one, customize it, and commit — all from
the terminal.

---

## Why git commit-at?

| | git commit-at | Manual commits | Cloud AI tools |
|---|---|---|---|
| **Private** | ✅ 100% local | ✅ | ❌ sends code to cloud |
| **No API key** | ✅ | ✅ | ❌ requires subscription |
| **Conventional commits** | ✅ auto | ❌ manual discipline | ⚠️ sometimes |
| **Branch visualizer** | ✅ built-in | ❌ | ❌ |
| **Commit history** | ✅ tracked | ❌ | ❌ |

---

## Install

```bash
npm install -g git commit-at
```

Requires: **Docker** (all AI/backend services run in containers — no extra setup).

---

## How to use

```bash
# 1. Stage your changes
git add .

# 2. Run the tool
git commit-at

# 3. First time: register/login at http://localhost:7860
# 4. Pick a suggested commit message
# 5. Confirm — done!
```

On first run, Docker starts Ollama, Redis, and the Gradio UI automatically.

---

## Features

- 🤖 **3 AI suggestions** per run, tailored to your actual diff
- 📋 **Conventional commits** — `feat:`, `fix:`, `refactor:`, `chore:`, etc.
- 🎫 **Ticket integration** — prefix messages with JIRA/Linear ticket numbers
- 🌿 **Branch visualizer** — live git branch DAG in the web UI
- 📊 **Commit history** — track everything you've committed across repos
- 🔐 **Session persistence** — stay logged in between runs
- 🐳 **Zero local dependencies** — everything runs in Docker

---

## Numbers

*(TBH — to be updated with real metrics)*

| Metric | Value |
|--------|-------|
| Average suggestion time | ~5–10 s |
| First-run setup time | ~30 s |
| AI model size | ~1 GB (qwen2.5-coder:1.5b) |
| Runs entirely offline after setup | ✅ |

## Quick Start

```bash
# Install
npm install -g git commit-at

# Go to any git repo
cd your-project
git add .

# Generate commit message
git commit-at
```

The first run starts all Docker services and opens the login UI at `http://localhost:7860`.
After login, you'll see 3 commit message suggestions based on your staged diff.
