DigestDiff

As AI developer tools go, DigestDiff is unusual because it never reads your source code. DigestDiff is an AI code history tool that analyzes commit history to produce release notes and summaries of how a codebase has changed over time.

Only the commit log is used, which suits teams that are wary of handing code to a third party.

The main saving is time.

Drafting release notes usually means scrolling through a log by hand, and DigestDiff automates that step.

The same digests can help new developers understand how a project evolved without wading through raw history, so onboarding gets a little easier.

DigestDiff relies entirely on the quality and detail of your commit messages, so a log full of "fix stuff" will give you thin output.

Good, descriptive commits will give you far more useful summaries.

A free tier lets you try it on a real repository before deciding whether it earns a place in your release routine.
