AO3 Reader Features:

- AO3 open to all kinds of fandoms, including Real Person Fiction.

- It's open to all ratings of fanfiction.

- The archive allows users to host meta fandom writings as well as fiction.

- Authors have the ability to lock story visibility to other AO3 members only to minimize search engine inclusion (some authors don't want their stories showing up in general Google searches.) AO3 allows of certain fandoms and story types (including songfic) that have been banned from FanFiction.Net.

- Users have the ability to link various pseudonyms and names under one account and also to "orphan" stories to remove their names from them.

- There's a complex tagging system so that stories can be searched by theme (romance, hurt/comfort), trope (steampunk AU, aliens made them do it), or whatever an author may choose.

- AO3 Users have the ability to import stories from other URLs.

- There are collections and challenges.

- The site has a "Kudos" button to show that you read a story and enjoyed it without having to leave written feedback.

- AO3 Authors have the ability to add new fandoms if they are not already listed without having to wait for a site administrator to add them.

- There's a warning system for common fannish triggers and controversial subjects, which an author can choose or choose not to use.

Readers can give stories kudos, which function similarly to likes or hearts on other sites. Readers can also leave comments or make public (and private) bookmarks.
