What are tokens and how are they used?

Does it work with all programming languages?

Yes, What The Diff is trained on a massive dataset and supports nearly all major programming languages including Python, JavaScript, Ruby, and more.

Is my code stored or used for training?

No, What The Diff does not store your code and does not use your private repository data to train its AI models.

Which platforms are supported?

It currently integrates with GitHub (via GitHub Marketplace) and GitLab.

Can I use it for open source projects?

Yes, What The Diff sponsors open source projects with a free plan for projects with a track record of 10+ contributors or 100+ GitHub stars.

How do I trigger a summary manually?

You can use shortcodes like 'wtd:summary' in your PR description or set the app to only trigger when a specific 'WTD' label is added.
