What Is a Changelog Generator?

A changelog generator is a writing and formatting tool for software release notes. It structures your project changes into the standardized Keep a Changelog format — grouping entries by version, date, and category so users and contributors can quickly understand what changed between releases.

Manually formatting changelogs is tedious and error-prone, especially across many releases. This tool handles the structure and formatting so you can focus on describing what actually changed. Enter your version number, date, and change descriptions, and get polished markdown output ready for your CHANGELOG.md file.

How to Use This Tool

  1. Set your version and date — Enter the version number following semver conventions (e.g., 1.2.0) and the release date. The tool formats these into the standard changelog header.
  2. Add change entries — Write or paste your change descriptions and assign each to a category — Added, Changed, Fixed, Removed, Deprecated, or Security. Each entry becomes a bullet point under its category heading.
  3. Organize and reorder — Drag entries between categories or reorder them within a category. The tool maintains proper markdown formatting as you rearrange content.
  4. Export your changelog — Copy the formatted markdown and paste it at the top of your CHANGELOG.md file. The output follows Keep a Changelog conventions and renders cleanly on GitHub, GitLab, and npm.

Frequently Asked Questions

What is a changelog generator?+
A changelog generator creates structured, formatted release notes for software projects. It organizes changes into categories like Added, Changed, Fixed, Removed, and Security following the Keep a Changelog standard, then outputs clean markdown ready for your repository.
What format does it use?+
The tool follows the Keep a Changelog convention, which is widely adopted across open-source projects. Entries are grouped by version number, date, and change type — producing markdown that's both human-readable and parseable by automation tools.
Can I customize change categories?+
Yes. Beyond the standard categories (Added, Changed, Deprecated, Removed, Fixed, Security), you can create custom categories that match your project's workflow — like Performance, Documentation, or Breaking Changes.
Does it auto-detect changes from git?+
This tool is a formatting and drafting aid. You input your changes manually or paste commit messages, and it structures them into proper changelog format. For git-based automation, tools like conventional-changelog integrate with your commit history.
Can I export to different formats?+
You can export as standard markdown (.md), HTML, or plain text. The markdown format is compatible with GitHub, GitLab, npm, and any platform that renders markdown changelogs.
Is my data stored anywhere?+
No. All changelog generation happens in your browser. No version data or change entries are sent to any server.
