Fair question. Most of the open-source tools I’ve seen focus on generating a single commit message from a diff. Zyg does that too, but the main idea is different: it treats your commits as raw material for project updates.

Instead of just producing “better commit messages,” it can take a series of commits on a branch and turn them into a narrative of progress - the kind of thing you’d actually paste in Slack, send to a PM, or have emailed to stakeholders automatically.
