commait: AI-generated git commit messages with a built-in diff compression pipeline

Writing commit messages is not hard, but it does take time. It may not be a lot of time but saving any amount of time is always good.commait is a CLI tool that reads your staged diff and generates a properly formatted conventional commit message in seconds. It also allows for token budgeting and is packaged with diff compression pipeline to enforce said budget.

Install

$npm install -g commait-cli

Key features

• Multi-provider: OpenAI or Anthropic, swap with a config change

• Fully configurable automation: auto-stage, auto-commit, auto-push, or keep every step interactive

• Token budget control: cap max diff tokens so costs stay predictable on large diffs

• Diff compression pipeline: if the diff exceeds your budget, a staged pipeline kicks in: strips noise files → strips headers → strips context lines → strips lines. Checks token count after each stage to minimize information loss

• Custom prompts: override the default to match your team's conventions

• Optional context flag: prefix the prompt with extra context via -c

• Interactive model picker: browse models without memorizing name strings
