What is AO3?
AO3 (Archive of Our Own) is a free, non-profit fanfiction archive run by the Organization for Transformative Works (OTW). It hosts over 12 million works of fan-created fiction, art, and other content across thousands of fandoms.
Unlike many other platforms, AO3 has no ads, no algorithm, and no paywall. It is entirely funded by user donations. The site won a Hugo Award in 2019, recognizing its importance to the creative community.
What makes AO3 different?
- No ads — completely funded by donations
- No algorithm — you choose what to read, not a feed
- Powerful tagging system — find exactly what you want
- Author-friendly — writers control their own works
- All fandoms welcome — from Harry Potter to BTS to obscure indie games
How to Browse AO3
You don't need an account to read on AO3. Just head to archiveofourown.org and start exploring. There are a few ways to find fics:
Browse by Fandom
Click Fandoms in the top menu to see categories like TV Shows, Movies, Books, Anime & Manga, Video Games, and more. Pick a fandom to see all the works written for it. This is the best starting point if you already know what you're a fan of.
Search for Something Specific
Use the Search bar at the top of any page to look for a specific title, author, character, or tag. For more precision, click Advanced Search to filter by word count, date, completion status, and more.
Use Tags to Explore
Every work on AO3 is tagged with details about its content. You can click on any tag to see all works that share it. For example, clicking "Slow Burn" shows every fic tagged as a slow burn romance, across all fandoms.

Understanding AO3 Tags
Tags are the heart of AO3. They tell you everything about a fic before you read it. This is the part that confuses most beginners, so let's break it down:
Relationship Tags: / vs &
This is one of the most important distinctions on AO3:
Slash (/) = Romantic or sexual relationship
Example: Draco Malfoy/Harry Potter = Draco and Harry as a couple
Ampersand (&) = Platonic or friendship relationship
Example: Draco Malfoy & Harry Potter = Draco and Harry as friends
Character Tags
Character tags list the characters who appear in the fic. The first characters listed are usually the main focus.
These use the full character name, like Hermione Granger or Steve Rogers.
Freeform Tags
These are flexible, author-created tags that describe the content, tone, or tropes. Examples:
Slow Burn, Hurt/Comfort, Coffee Shop AU,
Fix-It Fic, Angst with a Happy Ending. Authors sometimes use
freeform tags to add humor or commentary too.
Archive Warnings
AO3 requires authors to select from these archive warning tags:
- No Archive Warnings Apply — the fic does not contain any of the major warnings
- Creator Chose Not To Use Archive Warnings — proceed with caution; the content may or may not contain warned material
- Graphic Depictions Of Violence
- Major Character Death
- Rape/Non-Con
- Underage
Category Tags
Category tags describe the type of relationship focus: M/M (male/male), F/F (female/female), F/M (female/male), Gen (general, no romantic focus), Multi (multiple relationship types), or Other.

How to Find Good Fics
With millions of works on AO3, finding great fics can feel daunting. Here are proven strategies:
Sort by Kudos
Sorting by kudos surfaces the most-loved fics in any fandom or tag. It's the quickest way to find crowd favorites.
Check Bookmark Counts
High bookmark counts often indicate fics that readers loved enough to save and re-read. Sort by bookmarks to find hidden gems.
Use Filters Aggressively
The more specific your filters, the better your results. Include tags you like, exclude ones you don't. Filter for complete works if you hate waiting for updates.
Read the Tags Carefully
Tags are your best friend. They tell you the tone, content, and tropes before you invest time in a fic. Well-tagged works are often written by experienced authors.

Interacting on AO3
AO3 is a community. Here's how to participate and show appreciation for the works you enjoy:
Leaving Kudos
Click the Kudos button at the bottom of any work to show you enjoyed it. You can only leave kudos once per work. Even guest readers can leave kudos. It's quick, easy, and authors genuinely appreciate every one.
Leaving Comments
Comments are the gold standard of feedback. Even a short "I loved this!" means the world to a fanfic author. You can comment on individual chapters or at the end of a work. Be kind, be specific about what you enjoyed, and never leave unsolicited criticism of the author's creative choices.
Bookmarking
Bookmarks let you save fics for later. You can add private notes and tags to organize your bookmarks. Public bookmarks are also visible to other users, helping them discover great fics. Some readers use bookmark notes as mini-reviews.
Subscribing
Subscribe to a work to get email notifications when new chapters are posted. You can also subscribe to an author (to see all their new works) or a series (for new installments).
AO3 Etiquette Basics
- Don't repost someone's work elsewhere without permission
- Don't demand updates — authors write for free, on their own schedule
- "Don't like, don't read" — if a fic isn't for you, just move on
- Leave positive feedback — kudos and kind comments keep the community thriving
- Tag your own works accurately if you write, so readers can make informed choices
Frequently Asked Questions
Is AO3 free?
Yes, completely. AO3 is run by the non-profit Organization for Transformative Works (OTW) and is funded entirely by donations. There are no ads, no subscriptions, and no premium tiers. Everything on the site is free to read and use.
Is AO3 safe?
AO3 is safe to use as a website — no malware, no hidden charges. However, because AO3 allows a wide range of creative content, some works contain mature or explicit themes. The site provides robust tagging and warning systems so you can filter out content you don't want to see. Use the ratings and archive warnings to guide your reading.
What does a ship name mean?
A "ship" is short for "relationship." On AO3, ship names use a slash (/) between character names to indicate a romantic pairing (e.g., "Draco Malfoy/Harry Potter"), and an ampersand (&) for platonic relationships (e.g., "Steve Rogers & Bucky Barnes"). You'll also see portmanteau ship names like "Drarry" (Draco + Harry) used by fans outside of AO3's tagging system.
How do I filter out content I don't want to see?
Use AO3's built-in filters. On any tag or fandom page, use the sidebar filters to exclude specific tags, ratings, warnings, and categories. In the advanced search, you can enter tags under "Other tags to exclude." For a full walkthrough, see our AO3 Filtering Guide.
Can I read AO3 on my phone?
Yes! AO3's website works in any mobile browser. For an even better experience, try the Fanfict Reader app, which provides a clean, optimized mobile interface for browsing and reading AO3 fanfiction, with offline reading support and customizable reading settings.
