AO3 Reading Companion Firefox

AO3 Reading Companion

A personalized recommendation algorithm. Personalized AO3 feed with custom rows, reading queue management, and chapter update tracking. Everything stays local. NO DATA COLLECTED!

Features & Capabilities

Built by Disastrous-Class9057 from reddit.

AO3 doesn't have a recommendation algorithm. This extension builds one for you. Completely privately, on your own device. With no information sent out.

Tell the extension what you love (tags, fandoms, authors). Browse AO3 normally. Over time, it learns what works for you and surfaces fics you'd actually enjoy reading, organized into a personal feed.

What you get:

  • A multi-row feed with recommendations tailored to your taste. Including hidden gems, completed long reads, fresh chapters on your active reads, and discovery picks
  • My Reading dashboard with Save for Later, currently Reading, and Read sections finally manage your AO3 reading queue properly
  • Custom rows: define your own row like "Werewolf Long Reads, 50k+ words, complete, sorted by kudos" and the feed builds it for you
  • "Why this?" transparency on every recommendation and see exactly which of your preferences matched
  • Three-level dislike feedback (Never again / Less of it / Just from this author) that actually shapes future recommendations
  • Manual update checks for fics you're actively reading
  • Import your AO3 bookmarks to seed your Save for Later list
  • Full preferences dashboard to fine-tune tags, fandoms, blocked content, structural preferences, and more
What it doesn't do:

This extension stores all data locally in your browser. Nothing is collected, transmitted, or shared. Not with Mozilla, not with AO3 beyond your normal browsing, not with the developer. Your reading habits and preferences are yours alone.

The extension respects AO3's servers with a 10-second spacing between requests and pauses if it ever hits a rate limit. It only operates when you're logged into AO3 account.

Requires Firefox. Works on any AO3 user account.

Is AO3 Reading Companion Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

AO3 Reading Companion requires very minimum permissions.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

AO3 Reading Companion is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
