Show HN: Diny – Git diff commit messages (github.com)

Diny is a tiny CLI tool that generates git commit messages from your staged changes. It inspects git diff, filters out noise (lockfiles, binaries, build artifacts), and uses a self‑hosted Ollama server to produce concise, conventional-friendly messages — no external API key required. Features include an interactive workflow with multiple suggestions, smart regeneration that learns from prior attempts, a custom feedback loop for refining outputs, and a timeline analysis that summarizes commit history and message patterns. You can install via Homebrew (dinoDanic/tap/diny) or grab prebuilt binaries from GitHub Releases; it adds a git alias (diny auto) so you can run diny commit or git auto as part of your normal workflow. For the AI/ML and developer community, diny is notable because it applies local LLM inference to a narrowly scoped, high-impact task: improving commit hygiene and project auditability without shipping code or secrets to a cloud service. The self‑hosted Ollama backend gives faster, more reliable, and privacy-preserving generation compared with hosted APIs. Practically, it reduces friction for maintainable commit histories, aids time-tracking and client updates via daily summaries, and demonstrates how small, focused LLM integrations can automate repetitive documentation tasks while keeping control and transparency in developer hands.
