Build release notes from commit messages with categorization, contributor listing, and formatting.
This tool takes a batch of commit messages and turns them into a draft release notes document: each message is sorted into a category, the categorized items are assembled into a readable layout, and the people behind the commits are listed as contributors. The tool sees only the text you supply, so the notes are only as informative as the messages. The common surprise is that a cryptic or inconsistently phrased commit produces a cryptic or misplaced note - the generator can arrange and present what the messages say, but it cannot recover details the messages never contained.
The tool takes the commit messages you paste as its only input. It reads each message and assigns it to a category that reflects what the message says the change does - a fix, a new feature, a documentation update, and so on. Because the assignment depends on the message text, rewording a message and regenerating can move it into a different section.
Once every message has a category, the tool groups them under their section headings, gathers the contributing authors from the commit information, and lays the result out as a formatted release notes document ready to copy into a changelog, release page, or announcement. The output is a draft built from your messages: nothing is added that was not in them.
Categorization is driven by the message text, so consistent phrasing gives the most consistent results. Whether a specific style is required is not documented, but the practical behavior is that clearly worded messages sort predictably and vague ones may not. If the same kind of change lands in different categories on different runs, standardizing your message wording is the fix.
The tool runs in the browser and works only from the messages you paste, so the notes describe exactly that batch. Choose your range when copying the messages - for example, the output of a git log command limited to the period since your last release - and the notes will cover that span. Re-pasting a different range is how you change the scope.
The behavioral notes were checked against the browser implementation. Standards and primary references below define the relevant format, formula, or platform behavior.
