Diff Summarizer

Git diffs are great for seeing exactly what changed, but terrible for understanding why. Scrolling through hundreds of lines of red and green to figure out what a set of changes actually means is nobody's idea of fun. This tool takes a git diff and turns it into a plain English summary. Perfect for changelogs, PR descriptions, or just figuring out what happened in the last few commits.

One command. Zero config. Just works.
