The process
Describe the book
Enter title, author, publisher, and format. Upload a required base set of photos (front cover, spine, title page, copyright page, rear cover), plus dust-jacket, signature, or inscription photos when they apply -- BookLens analyzes edition, printing, and condition from that evidence.
We analyze edition and condition
HonestBookAI distinguishes between first editions, later printings, and notable variants. Condition cues from your photos and notes are evaluated against our grading framework.
We compare researched market evidence
Your book is compared against AI-researched market evidence, weighing confirmed completed sales more heavily than active asking prices. Outliers are identified and weighted appropriately.
You receive a valuation and explanation
A clear estimated value range plus the specific factors that drove it: edition significance, condition grade, current demand, and comparable sales.
What we look at
Printing history, publisher, binding variants, notable states, and bibliographic markers that distinguish a first edition from a later printing or a significant variant from a common copy.
Dust jacket presence and grade, board condition, interior quality, inscriptions, binding tightness, and specific defects — evaluated against our published condition framework.
AI-researched market evidence, weighted by recency, similarity, and whether a sale is confirmed or an asking price. Demand trends, outlier identification, and market depth are all factored into the range.
What we don't do
Transparency
Transparent methodology
Every valuation comes with the factors that drove it, so you can understand the result and the evidence behind it.
Real market evidence
Estimates are grounded in AI-researched market evidence, weighing confirmed completed sales more heavily than aspirational asking prices or catalog estimates.
Built within Page & Provenance
HonestBookAI is part of a platform built around provenance, grading, and the book trade. The expertise is structural, not bolted on.
Clear limits
When data is thin or a book's market is unusual, we say so. A confident estimate requires sufficient evidence — we don't invent certainty.
Education
Understanding how books are valued makes the results more useful. These resources are free and here for whenever you need them.
