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

It uses the GitHub API to access the diff of your pull requests, and then uses an AI model to generate a summary of the changes. It supports nearly all programming languages, and can be configured to ignore PRs from certain branches, choose which files should be included/excluded from the summary, and generate comments on-demand.

It can also send weekly Slack notifications of all changes that happened in your repositories. What-the-Diff helps teams improve their code review and continuous integration process, and is free to use as long as they provide it, with the option to upgrade to paid plans if needed.

Tokens are used to process the git diff of pull requests, with an average pull request being ~2,300 tokens. Unused tokens do not roll over to the next month, so users should select the smallest plan and upgrade when necessary.
