vibemit

AI-generated Git commit messages using a local LLM via Ollama.

How It Works

Reads your staged diff via git diff --staged

Sends the diff to a local Ollama model with a carefully tuned prompt

Parses the response into 3 distinct commit message candidates

Presents an interactive selection menu

Commits with the selected message (or copies/prints based on flags)

The model runs locally — no data leaves your machine.

Prerequisites

Node.js >= 20

Ollama installed and running

A pulled model (default: qwen3:8b)

# Install Ollama
brew install ollama        # macOS
curl -fsSL https://ollama.com/install.sh | sh  # Linux

# Start the server and pull the default model
ollama serve
ollama pull qwen3:8b

Install

npm install -g vibemit

Or run directly:

npx vibemit

Usage

Stage your changes, then run:

git add -p
vibemit

vibemit reads your staged diff, generates 3 commit message candidates using a local LLM, and lets you pick one interactively.

Flags

--model <name> Ollama model to use (default: qwen3:8b) --intent <text> High-priority intent guidance for commit wording --conventional Conventional Commit format (type(scope): subject) --body Include subject + body (1-3 bullet points) --dry-run | -d Print selected message, do not commit --clipboard | -c Copy selected message to clipboard, do not commit --yes | -y Auto-select the first option (skip prompt) --add-rule <text> | -r Add a persistent rule --rules Print saved rules --clear-rules Delete all saved rules

Examples

# Basic usage
vibemit

# Conventional commits with a body
vibemit --conventional --body

# Dry run with clipboard copy
vibemit -d -c

# Auto-select first option (for scripting)
vibemit -y

# Use a different model
vibemit --model llama3.2:3b

# Provide explicit commit intent
vibemit --intent "Initial scaffold for vibemit CLI with Ollama integration"

# Add a custom rule
vibemit --add-rule "Use lowercase for subject line"
vibemit --add-rule "Always mention the affected component"

# View and clear rules
vibemit --rules
vibemit --clear-rules

Flag Combinations

Flags Behavior (none) Select message, then git commit --dry-run Print only, no commit --clipboard Copy only, no commit --dry-run --clipboard Print and copy, no commit --yes Auto-select first, then commit --yes --dry-run Auto-select first, print only

Rules

vibemit supports persistent rules that are included in every prompt. Rules are stored per-repo when inside a Git repository, with a global fallback.

Storage locations:

Per-repo: .git/vibemit.json

Global fallback: ~/.config/vibemit/config.json

# Add rules
vibemit -r "Use lowercase for subject line"
vibemit -r "Always mention the affected component"

# View rules
vibemit --rules

# Clear all rules
vibemit --clear-rules

Development
