#ao3 userscripts

I'm back with a new userscript! This one was born out of my compulsive need to switch site skins throughout the day.

AO3: Skin Switcher lets you change site skins from anywhere on AO3 without losing your place. The skins are sorted alphabetically, and there's a home button in the top right corner that takes you to the site skins page.

There's also an Edit Mode, which is useful for site skin makers. Instead of activating a skin, it redirects you to the skin's editing page.

Installation

Get Tampermonkey (works on Safari / iOS, Chrome, Firefox).

Install the script from GreasyFork.

Under 'Userscripts' in the navigation bar, select Skin Switcher.

Not with skins, you’ll have to use userscripts:

IMPORTANT: "Quality Score" measures reader engagement (kudos-to-hits ratio adjusted for length), not the quality of anyone's writing. A lower score can reflect genre trends (i.e. omegaverse fics tend to score lower), smaller audiences, or a dozen other things unrelated to how good the writing is. This feature exists to help you, the reader, privately prioritize your reading list. That's it. Do not share scores on social media, send them to authors, or use them to rank or criticize anyone's work. In fact, don't discuss them with anyone at all. If I see this feature being weaponized against writers, I will unlist the script without warning.

So I've been working on this for way too long and it's finally ready to inflict upon the world ✨

AO3: Reading Time & Quality Score is basically two tools in one:

📖 Reading Time Bar - Shows you exactly how long a fic will take to read based on word count. You can customize your reading speed and it color-codes short vs medium vs long reads. You can optionally show reading times for chapters as well.

⭐ Quality Score Bar - It's a smarter kudos/hits ratio that actually accounts for fic length and word count. No more long fics getting punished just for existing, and no more rewarding authors who split chapters into tiny pieces.

By default, it hides the score bar on fics with less than 50 kudos as to not judge prematurely (you can customize this). You can even normalize it so the best fic in your fandom gets treated as the "perfect 100" baseline, which makes comparing easier.

Both features are completely independent - use one, use both, whatever you want!!

NOTE: The stat icons in the pics come from my Rose Pine site skin or Stat Icons with Hover Text (or any really any ZerafinaCSS skin).

Installation:

Get Tampermonkey (works on Safari / iOS, Chrome, Firefox).

Install the script from GreasyFork.

Visit any AO3 work and the bars will show up automatically

Honestly this started as a "quick weekend project" and then I spent way too much time fine-tuning the math and menu. But hey, now we can all make slightly more informed decisions about which 200k slowburn to start at 2am!

Let me know what you think! I'm planning to keep updating it based on feedback. :)

I'm trying to resist the urge to tinker with it again because it's already so pretty… It kinda feels like modding Skyrim—you spend so much time modding that you never actually play the game. 😭

Also, I cannot sing enough praises farin's AO3 Fictracker. You can use custom tags to highlight and hide works, plus track your reading progress. It's completely replaced the Mark for Later feature for me—I use it to fade out works I've already finished and add custom notes to remember where I left off reading. Seriously, go check out that amazing script!!

So this is something I've wanted for a while—a way to sync userscript data across devices. My Advanced Blocker blocklist on my phone and PC staying in sync. Works I collapse with Quick Hide on desktop staying hidden on mobile. No Re-Kudos history carries over everywhere, etc.

It works with any AO3 userscript that uses localStorage. You just pick which keys to sync, connect a Google Sheet as storage, and you're done. Your data stays in your own Google account, syncs automatically, and you can manage everything else directly from AO3.

It is not plug in play, be sure to carefully read the set-up instructions on GreasyFork.

Use for:

Advanced Blocker

Quick Hide

Reading Time & Quality Score

No Re-Kudos

Chapter Shortcuts

Auto Pseud

Huge credit to escctrl's Import & Export Script Storage for the local storage management and UI, and farin's FicTracker for the sync architecture.

It's been a long time coming and I'm so happy to finally release this one! The AO3: Advanced Blocker gives you complete control over what you see on AO3—block, highlight, or whitelist works based on tags, authors, word counts, and much more.

Tag Filtering

Blacklist, Whitelist, or Highlight Tags – Hide unwanted tags, show whitelisted tags, or make favorite ones stand out.

Wildcard Support – Use * to match partial tags ("Abandoned*" catches "Abandoned Work," "Abandoned WIP," etc.)

Conditional Blocking – Block tags only when other tags are missing. ( "Angst unless:{Fluff}" blocks "Angst" works unless they contain "Fluff").

Content Filtering

Block by author, title keywords, or summary keywords

Filter by word count, chapter count, language, or fandom count

Completion status filtering – Block complete or ongoing works

Primary relationship/character filtering – Only show works where your favorites appear in the first few tags

Staleness filter – Hide WIPs not updated in X months

Quality of Life

Quick-Add – Hold Alt and click any tag or author to instantly blacklist them

Per-filter hiding options – Choose between clickable placeholders or complete removal

Pause blocking and import/export settings

Installation

⚠️ Chrome/Brave/Edge users: You have an extra step! See instructions here.

Get Tampermonkey for Chrome, Firefox, Safari, or Edge

Install the script from GreasyFork

Navigate to any page with AO3 works and click Userscripts → Advanced Blocker to configure

Popping in to publish a new (somewhat self-indulgent) userscript. All it does is reorder relationship tags so romantic pairings (/) always appear before platonic ones (&) on work list pages.

Idk how but I keep finding new ways to mess with AO3! This script replaces the favorites section with a custom one. You can link to basically anything—not just tags. For example above I link to:

My custom bookmark tags from FicTracker

The Binggeable Binghe Fics collection

Works of my favorite authors, diushek and anatheme

Heavily filtered searches from my favorite fandoms

Unlike the normal favorites, the links can include filters and search options. This has saved me a loooot of time.
