Features

• 🧠 Local LLM — uses Ollama, no API keys needed

• 📝 Multiple commit styles — conventional, simple, detailed
• 🔍 Smart diff allocation — per-file context budget, code files prioritized over docs
• 🔎 Deep mode — summarize each file separately for better messages on large changesets
• 💡 Explain mode — summarize what changed without committing
• 🕐 Recent commits context — last 3 commits included in the prompt for better inference
• 🔄 Regenerate — not happy? generate a new message instantly
• ✏️ Edit before commit — open your editor to tweak the message
• ⚙️ CLI flags — control style, model, and more from the command line
• 📁 Config file — persist your preferences with komit init
• 🌍 Universal — works via pip, binary, or shell script
• 🪟 Cross-platform — Linux, macOS, Windows
• ⚡ Fast — runs on your machine, no network calls to external APIs
• 🔒 Ollama validation — checks if Ollama is running and model exists before generating
• 🔁 Smart updates — detects pip vs binary install and updates accordingly

---

Deep Mode

For large changesets with many files, --deep summarizes each file individually before generating the final commit message. More accurate, but slower since it makes one LLM call per file.

komit --deep

---

Explain Mode

Explains your staged changes in plain English without committing — useful for code review prep or PR descriptions.

komit --explain

---

Branch Name Parsing

When --include_branch_name is enabled, komit reads your branch name to infer the commit type and scope automatically.

Branch	Inferred type	Inferred scope
feat/auth-login	feat	auth
fix/ui_button	fix	ui_button
refactor/api-layer	refactor	api

Supported types: feat, fix, chore, docs, style, refactor, test, ci, perf.

---

Configuration

Run komit init to create your config file at ~/.config/komit/config.toml:

model = "qwen2.5:7b"
style = "conventional"
ollama_url = "http://localhost:11434"
max_diff_length = 4000
timeout = 60
include_branch_name = false

CLI flags always override config file values.

---

Commit Style Outputs

Conventional (default)

feat: add user authentication
fix: resolve null pointer in response pipeline

Simple
