Changelog Generator

Writing changelogs by hand is tedious. This tool reads your git history between two refs and generates a properly categorized changelog entry. No more copy-pasting commit messages.

One command. Zero config. Just works.

Quick Start

npx ai-changelog --from v1.0.0 --to v2.0.0

What It Does

Reads git log between any two refs (tags, branches, commits)
Groups commits into Added, Changed, Fixed, Removed
Cleans up messy commit messages into readable entries
Outputs markdown ready for your CHANGELOG.md

Usage Examples

# Between two tags
npx ai-changelog --from v1.0.0 --to v2.0.0

# From a tag to HEAD
npx ai-changelog --from v1.0.0 --to HEAD

# Write directly to file
npx ai-changelog --from v1.0.0 --to v2.0.0 -o CHANGELOG.md

# Specific commit range
npx ai-changelog --from abc123 --to def456

Best Practices

Tag your releases - makes generating changelogs way easier
Write decent commits - garbage in, garbage out
Review the output - AI might miscategorize some changes
Run before release - make it part of your release checklist

When to Use This

Preparing a release and need changelog entries
You forgot to maintain the changelog and need to catch up
Want consistent changelog formatting across releases
Generating release notes for GitHub releases
