Archive of Our Own

What Archive of Our Own is
Archive of Our Own (AO3) is a nonprofit hosting site for transformative fanworks such as fanfiction. It is a project of the Organization for Transformative Works, a nonprofit established by fans, and runs on donations; users do not pay, and the site has no advertisements. Work Search can find works by tag, title, author, word count, hits, kudos, publication date, and language. Filters cover rating, warning, category, fandom, character, relationship, and freeform tags. Works can be downloaded as AZW3, EPUB, MOBI, PDF, or HTML, though each download includes all available chapters rather than a single chapter. Readers can change site colors, fonts, and layout with site skins, and customize individual works with work skins. AO3 aims to be compatible with common desktop browsers, e-readers, screen readers, and default browsers on most iOS, Android, and Windows mobile devices. The archive is built on open-source software designed by and for fans. An invitation is required to create an account; AO3 says this helps keep growth within its hardware, bandwidth, and support capacity. Mobile apps are not currently available, and a public API is several major releases away on the roadmap.
