About this extension
For people with too many open tabs.
Trace helps you keep track of what you saved, where you stopped, what you dropped, and what you meant to come back to.
The Trace extension works on AO3 and FanFiction.net while you browse. It adds small status labels to archive pages so you can see whether a fic is already in your library, what reading status it has, and where you left off.
You can add stories to your Trace library without leaving the archive, then find them later from your phone or laptop.
Trace is an unofficial AO3 and FanFiction.net companion. Your library is private, story text is never collected, and there are no ads or data selling.
This extension is source-available at https://github.com/tracefiction/trace-browser-extension
Sign up free at tracefiction.com. The main features are free for up to 100 stories; Trace Unlimited removes the story cap and adds reading stats.
