What is What-the-Diff?

What-the-Diff is an AI-powered app that reviews the diff of your pull requests and writes a descriptive comment about the changes in plain english.

We process the git diff of your pull requests to generate a descriptive comment. Big diffs need more tokens for processing. Average pull requests are ~2,300 tokens.

How does What the Diff work?

Our application uses the GitHub/Gitlab API to get the diff of your pull request and then uses an AI model to generate a description of the changes. We don't store your code.

Does it work with all languages?

Yes, we support nearly all programming languages and the AI is able to explain the diff in plain english – or one of the other languages that we support.

What happens if I run out of tokens?

If you run out tokens, you can upgrade to a bigger plan or wait until your next billing cycle. We don't upgrade your plan automatically.
