Show HN: Build the habit of writing meaningful commit messages (github.com)

smartcommit is a new AI-powered CLI that helps you produce semantic, Conventional Commits-style messages by analyzing your staged git diff, asking targeted questions about intent, and generating a structured commit message you can edit or confirm. Built in Go with a Bubble Tea terminal UI, it supports OpenAI (GPT-4o) for cloud accuracy and Ollama (Llama 3.1) for a local, privacy-preserving option. You can install via go install or build from source, configure it as your git commit alias, and it will detect an OPENAI_API_KEY automatically if present. For AI/ML and engineering teams this matters because consistent, meaningful commit messages enable better traceability, changelog generation, semantic-release workflows, and code review context. The tool strictly enforces Conventional Commits (feat, fix, chore, etc.), prompts for the “why” behind changes (not just the “what”), and stores config locally (~/.smartcommit/config.json). It balances accuracy and privacy with multi-provider support and an interactive Q&A loop so commits reflect author intent—reducing noisy history and improving downstream automation in CI/CD and release tooling.
