The films
Five stories. One library.
Ninety seconds each. Pick whichever sounds like you.
Who is this for?
Your library, finally cataloged.
You have hundreds of books. Maybe thousands. You know what you have — roughly. LumiLexicon turns your shelves into a searchable collection with cover images, condition notes, and real market values.
- Shelf scan — Photograph an entire shelf. AI identifies every spine and builds individual records. One photo, dozens of books.
- Gallery view — Browse your collection by cover. Filter by genre, era, or author.
- Know what it’s worth — Not because you’re selling. Because you should know. Insurance, curiosity, estate planning.
One photo of a shelf. Every spine identified, every edition cataloged.
From thrift store to listed in minutes.
You buy at estate sales, library sales, and thrift stores. You need to know what a book is worth before you buy it, and you need to list it fast once you get home. LumiLexicon handles both.
- Quick snap — Point your phone at a book in the field. Get an ID and a value estimate in seconds. Decide before you buy.
- Market valuation — Real sold comps from eBay and AbeBooks. Condition-adjusted. Not wishful thinking.
- Cross-platform listing — Generate listing copy for eBay, AbeBooks, Amazon, and Etsy. One book, every marketplace.
Five ways in — Quick Snap works fastest when you’re standing in a garage sale.
Walk-in intake, sorted.
Someone walks in with a box of books. You need to figure out what’s worth buying and what to offer. LumiLexicon gives you fast identification, market-based pricing, and a way to track every acquisition through to sale.
- Barcode scan — For books with ISBNs, scan and go. Instant identification and market data.
- Quick valuation — See comparable sales immediately. Make confident buy offers without guessing.
- Operations & P&L — Track your costs, revenue, and margins by lot. Know which buys made money.
The back office — costs, revenue, and sell-through for every acquisition lot.

Quick Snap
Point your phone at a book. Know it in seconds.
No barcode required. Snap the cover and Claude vision reads the title and author, sets a value range from real sold comps, and builds a full catalog record — blurb, tags, edition, and market data — in one pass. Here, a 1932 first edition of Aldous Huxley’s Brave New World, start to finish.
Capture
Four ways in. One clean record.
Snap a cover, photograph a whole shelf, scan a barcode, or drop photos you already have. Every path lands at the same rich metadata review — ranked by what works for the book, not what looks prettiest in a grid.
Computer vision
Point a camera at a shelf. Get every spine.
One photo of a full shelf is detected spine-by-spine, the text is read off each one, and Claude identifies the title, author, and edition — including pre-ISBN books a barcode scanner can’t touch.
The record
A record worthy of the book.
Vision reads covers, title pages, and copyright pages to fill in edition, publisher, and printing. Then real comps from AbeBooks and eBay set an honest value range, and platform-specific listings write themselves.
Ask Lumi
Ask your inventory anything.
Semantic search over your whole catalog, in plain language. Ask which books haven’t been valued, what your oldest editions are, or how value breaks down — and Lumi answers with real numbers and charts.
Back of house
Know which buys made money.
Revenue, fees, shipping, and cost basis roll up into a live P&L — sell-through by lot, AI spend per book, the whole operation by the week. Not selling? The same valuations tell you what your shelves are worth, for insurance, estate planning, or just knowing.
Reading room
Your collection, beautifully shelved.
A gallery built for browsing, not spreadsheets. Flip through covers, surface a featured volume, and read the full record of anything on your shelf — sellers and collectors alike.
Start building your catalog
Whether you’re selling rare books or organizing a personal library, every volume starts here.
lu·mi·lex·i·con
LumiLexicon /ˌluːmɪˈlɛksɪkɒn/ n.
From the Latin lumen (light, brightness): literally “full of light, shining”; figuratively, “clear to the understanding — lucid, manifest.” And the Greek lexikon biblion (a book of words), from legō : to speak, and the Proto-Indo-European leǥ- : to gather, to collect. A gathering of knowledge, brought to light.
