Tweet Diff is a Chrome add-on designed to enhance the Twitter experience by providing users with a detailed diff checker for their tweet edit history. This tool allows users to easily view the changes made to their tweets, making it simpler to track edits and understand how content has evolved over time.

The add-on is free to use, and it caters to those who wish to analyze their tweet modifications effectively. By highlighting the differences between the original and edited versions of tweets, Tweet Diff offers a clear visual representation of changes, which can be particularly useful for users who frequently update their posts.
