Shelfsort

In loving memory of Tamy N Thomas — a lover of fanfiction. This website was built with her, and those with many fanfiction EPUBs, in mind, and she never got to see it. 1978 – 2026. Always remembered. Never forgotten.

A quieter way to organize ebooks

Your EPUBs,
sorted by fandom.

Got a Downloads folder full of nameless EPUBs? Shelfsort reads the metadata and uses AI to file them by Harry Potter, Twilight, Marvel, original fiction, and anything else hiding in there. Then it gives them a home — a clean reader, a year-end recap, friends to talk about them with, the works.

Built by one person, in the open.

AI + metadata

EPUB metadata first, Claude as a quiet second opinion when the title alone won't tell.

Folders that feel right

Fanfiction nests by fandom. Original fiction and non-fiction stay tidy on their own shelves.

More than a sorter

A whole little world for your reading life.

Shelfsort is built for people who read the way you do — bouncing between a 200k-word AO3 fic, a non-fic on the nightstand, and three half-read novels. Here's what you get the second you sign in.

Year in Books, Wrapped

A nine-slide cinematic recap at the end of every year — books opened, pages turned, longest streak, top fandom, top author, bookends. Download it as a PNG, paste it into Threads or iMessage, watch friends ask what you've been reading.

A reader that respects your eyes

EPUB, PDF, TXT and DOCX all open inline. PDFs render natively via pdf.js — no re-conversion, no quality loss. Reading position syncs across devices, bookmarks remember the chapter you loved, dark mode follows your OS, and there are zero ads. Ever.

Goals, streaks & status

Tag books as want-to-read, reading, or read with one tap — filter your library by any state. Set a goal of 30 books, or 200 hours, or a fandom marathon. We track quietly, fire confetti when you hit it, and never guilt-trip you on a Tuesday.

A Reading Queue that actually helps

A dedicated 'up next' list separate from your library so you know exactly what to pick up when you finish tonight's book. Reorder by drag, pin favourites to the top, and see the total estimated reading time so you can plan a weekend or a flight.

Friends who actually read

Pick a one-of-a-kind @handle, add friends by username, see how many books overlap with theirs, send recs, share a peek at your shelf — all opt-in, all revocable.

Book clubs, with chapters

Spin up a private room, pick the book, set a chapter-per-week pace. We auto-post discussion prompts, members chat inline, and a weekly digest email keeps the slow readers in the loop.

Polish Library — bulk fix messy metadata

Inherited a Downloads folder of AO3 exports with 'Unknown' authors and mangled titles? Polish Library scans your whole collection at once, suggests corrections you can accept in a click, and rewrites the fixes back into the EPUB itself so the corrections travel with the file.

Preset Marketplace

Not sure how to organize? Browse community-shared library layouts — 'Regency romance shelf by trope', 'MCU fics by pairing', 'Non-fic by topic' — apply one in a click, tweak to taste, or publish your own for others to remix. Comments and stars on every preset.

Fix single files, in place

Prefer to correct one book at a time? Every card has a two-click edit — title, author, series, fandom, cover. Corrections are rewritten straight into the EPUB, so when you re-download or send to a friend, the fix travels with the file.

What it looks like

Three messy folders in. Three tidy shelves out.

Here's the same library a friend tested with on day one — 11 EPUBs dropped in as a single zip, organized in under a minute. No tagging, no renaming, no Calibre wrestling.
