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. Follow fandoms as Interests for a balanced Discover feed. When a search is worth keeping — one fandom, complete works only, 50k and up, sorted by kudos — save it as a Custom Feed and return in one tap. A reader worth spending three hours in. The font catalog adapts its recommendations to the script you are reading and can use fonts already on your device. Verified Chinese font packs are available on demand and stay on this device. Choose from four themes, then tune size, line spacing, and page margins. Close the app mid-chapter, come back next week, land on the same paragraph. Before you commit to a 200k WIP, the Reader's work menu 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 by default. Nothing to sign up for, no ads, no IDFA, no cross-app tracking. Reading on more than one phone? An optional AO3X account can back your library and progress up and restore them on the next device. It's off until you switch it on — signing in by itself uploads nothing, and downloaded chapters never leave the device at all. 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.
