Who it's for

DIY book archivists, r/DataHoarder preservationists, small special-collections librarians, and families holding rare or estate books. Today they cope with: flatbed scanner + ScanTailor (free but 3-6 hours/book and a brutal learning curve), vFlat-style mobile subscriptions that upload pages to the cloud, or vendor digitization at $30-100/book that often destroys the binding.

The problem

Time and money: 3-6 hours per book on the free stack, $30-100/book at vendors (with the book guillotined), or a recurring subscription that ships your rare book's pages to someone else's cloud — while AI companies are literally buying and destroying these books this month.

How to build it

Desktop app (Mac/Win/Linux), no accounts: drag in any phone page-flip video, preview flagged frames, export PDF/A + EPUB + Internet Archive-compatible scandata. Works with any camera app; no custom hardware.

How it makes money

One-time $59 license ($99 institutional tier with scandata.xml export): this crowd already pays vFlat subscriptions and vendor per-book fees, and the free alternative costs hours per book and cannot ingest flip video, so $59-once-local is an easy switch.

Why it doesn't exist yet

Incumbents skip it: vFlat/Adobe Scan are built for per-page receipt capture and assume cloud upload; gutter dewarp, spread splitting, page-order-from-video, and archive formats are a niche they ignore; flatbed makers sell hardware, not pipelines. The indie gap: open vision models for blur ranking, page-frame matching, and dewarping just got laptop-cheap (see this week's DeepSeek vision drop), and the preservation community will tolerate a scrappy v1 today.

First users

Two 500-700pt HN threads this week full of people asking 'how do I help scan rare books before they're destroyed' — ship v1 into the DIY Book Scanner forum, r/DataHoarder, and those exact threads; the demand is explicitly assembled and waiting.

Build size

2 people x 10 weeks. Included: video ingest + frame blur ranking, spread splitting, gutter dewarp, OCR (Tesseract/Surya), PDF/A + EPUB + scandata export, QC manifest. Excluded: mobile app, any cloud service, scanner-hardware integration, destructive-scan workflows.

Biggest risk

vFlat or Adobe Scan ships page-flip video capture with dewarp in a point release (or Apple folds it into iOS document scanning), collapsing the paid indie niche overnight.

Conditions for a hit (all 3 required)

• Ingests a single handheld page-flip video from any phone camera (~1 page/second) and outputs a searchable PDF/A plus EPUB of a 300-page bound book in under 30 minutes on a laptop, with a QC manifest listing every dropped or blurred frame.
• Automatically splits two-page spreads and flattens gutter curvature with zero manual cropping — verifiable by checking that output page count and order match the book's printed sequence with no human edits.
• Completes a full book end-to-end with networking disabled: all processing local after install, provable by running with Wi-Fi off.
