MangaDex helpers is a free Chrome extension developed by JesHal that aims to provide useful features for MangaDex users. Currently, the extension focuses on addressing the lack of search features on MangaDex, particularly when trying to find manga with a large number of chapters for binge-reading.

One of the main features of MangaDex helpers is the display of the highest chapter number for a manga in search page results. This is indicated by an orange number before the manga title. The extension utilizes the Chapter Language Filter from MangaDex user settings to determine which languages' chapters should be counted. While there may be rare cases where the extension provides an incorrect value, the developer has not encountered any such issues so far.

It is important to note that MangaDex helpers only displays the highest chapter number for the selected languages, rather than counting the total number of chapters. For instance, if a manga has only one uploaded chapter, but its chapter number is 96, the extension will display the number 96.
