FAQs

What are tokens and how are they used?

Tokens represent the amount of code processed from your pull request diffs to generate descriptions and summaries. Larger diffs require more tokens. An average pull request uses approximately 2,300 tokens, and plans are based on monthly token limits.

Does What The Diff store my code or train its AI model with it?

No, What The Diff does not store your code or the diffs of your pull requests. It uses the GitHub/GitLab API to read the diffs for processing and explicitly states that it does not train its AI model with your code.

Why does What The Diff require full access to my code repositories?

Due to limitations in GitHub and GitLab permissions, there isn't a specific permission to only read the diff of a pull request. Therefore, What The Diff requires full access to your code to be able to retrieve and process the diff information.
