# Proofreading Diff > Track and analyze changes made during the proofreading process URL: https://store.crowdin.com/proofreading-diff Category: Manager Productivity, Translator Productivity Type: App Author: Awesome Crowdin Proofreading Diff is a Crowdin report app that makes it easy for you to track and analyze changes made during the proofreading process. This tool can help you provide a thorough feedback to translators about their work. Please be aware that proofreaders on Crowdin are permitted to delete translations made by translators. If any translations have been deleted by a proofreader, you will not see a record for that segment in your report. It is recommended that you communicate with proofreaders to only suggest improved translations, rather than deleting existing ones. You can track translations that have been deleted in the 'Activity' section of your project. ![Post Edit Distance Report in Crowdin](https://developers.app.crowdin.net/api/media/file/d41a07a8-7188-48f4-b118-d924fd35ef00.png) > Edit Distance represents the Levenshtein distance between two strings as a percentage.
