Frequently Asked Questions

Find answers to common questions about WhatTheDiff

What is What The Diff?

What The Diff is an AI-powered tool that reviews pull request diffs and generates clear, descriptive comments about code changes in plain language.

What are tokens in this context?

Tokens measure the amount of data processed. Larger diffs consume more tokens. Typical pull requests use around 2,300 tokens.

How does What The Diff operate?

It uses GitHub or GitLab APIs to fetch pull request diffs and employs AI models to generate change descriptions. Your code remains private.

Does it support all programming languages?

Yes, it supports nearly all languages, and the AI can explain diffs in plain English or other supported languages.

What if I run out of tokens?

You can upgrade your plan or wait for the next billing cycle. Automatic plan upgrades are not available.

Is my code stored by the service?

No, your code is not stored. We only access pull request diffs through GitHub or GitLab APIs.

Do unused tokens roll over to the next month?

No, unused tokens do not carry over. Choose your plan carefully and upgrade as needed.

Does the AI learn from my code?

No, we do not train our models with your code. Your data remains private and is not used for AI training.

Why do you require full access to my repositories?

Currently, GitHub and GitLab permissions only allow full access to the repository. We need this to fetch diffs reliably.
