AO3 Story Tracker by marciepublishes

AO3 Story Tracker helps you keep track of fanfiction on Archive of Our Own without relying on a pile of tabs, browser bookmarks, or memory alone. Track works directly from AO3 pages, organize them in a personal sidebar library, and sort them with both built-in reading statuses and custom categories.

Use it to mark works as For Later, Reading, Completed, Re-reading, On Hold, Did Not Finish, or Deleted, while also creating your own categories for any system that makes sense to you. Add notes and star ratings, save chapter progress for reading and re-reading works, and jump back into a work from the chapter where you left off.

The extension also includes a popup control center for sorting, theme controls, custom category management, library tools, and quick reading insights. Dark mode and Solarized themes are included, and tracker data can be imported or exported for backup.
