Scan a shelf
In a bookstore, at a library sale, in front of a friend's bookcase — take one photo, or upload one from your library. Nothing to type, nothing to aim spine by spine.

Point it at a shelf.
Take one photo of a bookshelf. Quillwort reads every spine it can see, ranks the books against your own taste, and points each one back to its spot in your photo — so the last step is reaching out and pulling it down.
Every one points back to your photo.
How it works
One photo, three steps.
02 · Rank
Ranked to your taste
Tap "AI recommended" and every book it named is scored out of 100 against your own reading — with one sentence, written to you, about why.
03 · Locate
Find it on the shelf
Tap a book and your photo opens zoomed onto that exact spine, outlined in gold. Look up, find it, pull it down. That's what the whole thing is for.
Personal match
Fit, not fame.
The score isn't a star rating or a bestseller list. It's how well a book fits you, judged only against your own taste — a famous classic that's wrong for you scores low, and an obscure book that's right for you scores high.
- Your taste comes from your Goodreads history, topics you reach for, and books you'd read again. Goodreads is the fastest way in — never required.
- Quillwort writes your portrait in plain English. You can read exactly what the ranking thinks of you, and remove anything that isn't right.
- Every score carries a reason, written to you: "Why it found you."
- When a spine couldn't be read well enough, it says "Not yet ranked" — it won't guess.
While it works
A wait worth watching.
A big shelf takes a minute or more to read, and Quillwort doesn't pretend otherwise. Instead of a spinner, you watch it work: books outlined in your photo as they're found, two counters climbing, real titles arriving one by one.
- Walk away whenever you like — "Leave this open or don't, we'll bring you back." The scan waits with the rest of your scans.
- If the photo came out too unclear to read, it says so plainly — "That's down to the photo, not your shelf" — and the retake is free.

Privacy
Who sees what, plainly.
No other reader can see your scans. Quillwort's operators can open them, in our own administration tool.
The camera is used only when you choose to photograph a shelf or scan a friend's code.
Quillwort never receives your Goodreads password — the import reads a file you download yourself.
Delete a scan and its photo is gone from our storage within 9 days. Your whole account can be deleted from inside the app.
Questions
Asked, answered.
Does it read every book on the shelf?
It names the books whose spine lettering comes through clearly. Worn, tiny, angled
or hidden spines may be missed — and when a photo read badly, the app says so and
offers a free retake.
Do I need Goodreads?
No. Goodreads is the fastest way to fill in your taste — years of ratings in one
import — but you can build your compass from topics you type and books you'd read
again. Quillwort never asks for your Goodreads password.
What does the match score mean?
How much you would want this book, out of 100, judged only against your own taste.
50 is neutral; 85 and up is kept for books it's confident you'd love. It measures
fit, not quality or fame.
Is it instant?
No — a big shelf takes a minute or more, and the first scan after a quiet spell
adds about a minute while the readers wake. You watch it work, and you can walk
away; the scan waits with the rest of your scans.
Does it work offline?
Reading and ranking happen online. If your connection drops mid-scan, the scan
keeps going and waits for you, but it needs a connection to finish.
