twiffs is a Chrome browser extension that offers a native-like experience for displaying diff highlighting in edited tweets. It utilizes a dynamic programming solution to the LCS problem to identify the common subsequence between two chosen tweets and highlights them correspondingly. By making use of native Twitter elements, twiffs provides a user experience that closely resembles the platform itself.

To use twiffs, simply navigate to the edit history of any edited tweet, click on the diff icon of an older tweet, select a newer tweet for comparison, and witness the highlighted differences between the two selected tweets. This tool enhances the visibility of changes made to tweets, aiding in better understanding edit histories.
