AO3X: AO3 Unofficial Reader

Free, no ads, no account. Every AO3 search field, tag blocks that hold across the whole app, and a library that never leaves your phone.

Block a tag once and it stays blocked — in Discover, in Search, and on every tag page you open after that.

AO3X is an independent reader for Archive of Our Own. Same archive you already read on, in an app that's actually built for reading it.

And the search you keep rebuilding by hand — one fandom, complete works only, 50k and up, sorted by kudos — save it as a preset and it's one tap from then on.

A reader worth spending three hours in. Serif or sans, four themes, and real control over size, line spacing, and justification. Close the app mid-chapter, come back next week, land on the same paragraph.

Before you commit to a 200k WIP, the work page shows the rating, every archive warning, the full tag list, the summary and the stats — so nothing catches you off guard on chapter 14.

All of it stays here. Library, history, how far you got: on this device, not on a server. Nothing to sign up for, no ads, no IDFA, no cross-app tracking.

AO3X is unofficial. It is not affiliated with, endorsed by, or sponsored by Archive of Our Own or the Organization for Transformative Works. It reads publicly available AO3 pages; the works themselves remain subject to AO3's own policies.
