BiblioScan's answer:

BiblioScan reads entire bookshelves from a single photo. Its AI recognizes every book, even when seen only from the spine or partially hidden, without scanning barcodes one by one. Each title is instantly matched to real resale data and ranked by profit potential through our proprietary BiblioRank sorting, so the most valuable books rise to the top automatically.

Diffyn's answer

Diffyn is the platform that specializes on both change management and multi-model analysis.

BiblioScan's answer:

Most resale tools require you to scan ISBN barcodes individually, book by book. BiblioScan lets you photograph a full shelf and sort hundreds of books by profit in seconds. It combines four scan modes (shelf photo, continuous barcode, OCR, and manual ISBN/ASIN/EAN), live pricing across four markets (FR, US, DE, ES), full Amazon sales history, instant buyback prices, and real-time sync across iOS, Android, and we, with Excel/CSV export and shareable public links. It scales from a single box of books to professional FBA-level volumes.

Diffyn's answer

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.

BiblioScan's answer:

BiblioScan was built to solve a problem every book reseller knows: figuring out which books are actually worth selling is slow and tedious when you have to scan each barcode by hand. The idea was to let anyone simply photograph a shelf and let AI do the res, identifying every book, pulling real market data, and surfacing the hidden gems. What started as a faster way to evaluate used books became a complete tool for buying and reselling smarter, available on iOS, Android, and web.
