Who on your team writes the changelog, and how many releases behind is it? Does anyone open it apart from the person who has to update it? The Changelog Generator takes the raw material you already have, a diff or a list of commits, and turns it into an entry a user can read without knowing your branch names.
Short answer: Changelog Generator converts commits, diffs or rough release notes into a formatted changelog entry for a version, grouped into sections such as added, fixed and changed, and written in the convention your repository already follows.
What is Changelog Generator?
Changelog Generator is a free tool that writes release documentation from developer shorthand. Paste a git log, a diff or a handful of notes, and it groups the work into readable sections, drops the noise like merge commits, and rewrites each line so it describes the change from the user's side rather than the code's side.
How Does Changelog Generator Work?
The prompt box asks for your diff, changes or notes, and it is happy with messy input. A pasted git log --oneline between two tags is usually enough.
- Paste the commits or diff into the prompt box.
- Set Output Type to Changelog, since the same panel also produces commit messages, PR descriptions, README text and release notes.
- Choose a Convention and a Length, then generate.
- Copy the entry, or download it as TXT, Word or HTML for the release ticket.
The output card shows the entry with a word count, and previous runs stay in the activity history panel.
Grouped sections
Work arrives sorted into added, fixed and changed instead of one flat list of commits.
User facing wording
Each line is rewritten to say what changed for the person using your software.
Straight into the release
Copy it out, or download as TXT, Word or HTML for the release ticket.
What To Paste In From Your Git Log
The tool can only describe changes it can see. These four inputs raise the quality of the entry more than any option does.
- ✅ Commit subjects between the last tag and this one
- ✅ Issue or ticket numbers, so they survive into the entry
- ✅ One line on anything that breaks compatibility
- ✅ The version number and date you are releasing under
Tip Paste the commit subjects rather than the full patch. Subjects carry the intent, while a large diff spends the model's attention on code it does not need to summarise.
Convention, Length And The Emoji Switch
| Option | What changes | Suggested value |
|---|---|---|
| Output Type | Which artefact you get from the same notes | Changelog |
| Convention | Whether entries follow Conventional Commits, plain prose or your Team Standard | Conventional Commits if your repo already uses it |
| Tone / Detail | How formal and how explanatory each line reads | Concise for patch releases, Detailed for a major one |
| Length | Short, Normal or Detailed output | Normal, then raise it for a release with breaking changes |
Four toggles finish the panel: Follow Convention, Include Sections, Add Emojis and Include Examples. Include Sections is the one worth keeping on, because grouped headings are what make a changelog scannable. Add Emojis suits a public repository and rarely suits an enterprise one.
Reading The Draft Before It Ships
Check three things. Does every breaking change appear, and is it labelled as breaking? Does each line say what a user can now do, rather than which function was renamed? Are the ticket numbers still attached? Anything the commits did not mention will not appear, so add it by hand. When your release thread has grown long, run it through the Text Summarizer first and paste the summary in.
Purpose built tools are what EizTools does, free and without a login, with a model selector so you can try another engine on the same notes. The Changelog Generator sits with the rest of the developer tooling in the coding tools category, each one carrying its own options rather than a shared settings panel.
Frequently Asked Questions
Does it follow Keep a Changelog style?
Ask for it in the prompt and set Include Sections on. You get the familiar Added, Changed, Fixed and Removed groups, with your entries sorted into them.
Can it write the commit messages too?
Yes. The Output Type dropdown covers Commit Message, PR Description, README and Release Notes from the same panel, so one set of notes produces several artefacts.
What if my commit messages are poor?
Add a sentence of context in the prompt for each unclear commit. The tool rewrites what you give it, so vague input produces a vague entry.
Is anything I paste stored?
The activity history panel keeps your recent generations for the session only. Even so, paste commit subjects rather than proprietary source code.
A changelog is written once and read for years, usually by someone deciding whether to upgrade. Getting the first draft out of your commit history removes the excuse for skipping it, and leaves you editing rather than starting. Paste your log above and see how much of the entry writes itself.
