Frequently asked questions

If you have anything else you want to ask, reach out to us.

    • 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.

    • What are tokens?

      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.

    • Do you store my code?

      We don't store your code nor does any of our 3rd party services. We only use the GitHub/Gitlab API to read the diff of your pull requests.

    • Do keep unused tokens add up?

      Unused tokens do not roll over to the next month, so make sure to select the smallest plan and upgrade when needed. You can always downgrade to a smaller plan.

    • Do you train your AI model with my code?

      We don't do that and couldn't do that if we wanted – because we don't store your code or diff of your pull request at all.

    • Why do you need full access to my code?

      Unfortunately, there is no GitHub/Gitlab permission to only read the diff of a pull request. We need full access to your code to be able to read the diff.
