AO3
/eɪ oʊ θriː/
CommonArchive of Our Own, the major fanfiction platform used mostly by older and more dedicated fandom writers.
Used both literally (as the site name) and as a vibe descriptor. 'AO3 energy' implies more emotional weight and craft than Wattpad, and usually a more adult or queer fandom lens.
