DRM-Free Book Search Engine
Build a cross-store search product that lets readers find DRM-free ebooks by title, author, format, and storefront, then routes them to the best purchase option. The strongest demand signal in the discussion is not for more reading apps, but for better discovery and pre-purchase transparency.
為什麼這很重要
You want to buy an ebook you actually own, but the buying process becomes detective work. You search one store, then another, then a publisher site, and still cannot tell whether the file will be portable, downloadable, or locked down. Even when a seller supports unrestricted files, that information is often buried behind filters or hidden until late in checkout. The result is wasted time, abandoned purchases, and distrust. A focused search engine that answers one question clearly before you click buy would remove the main friction for this audience.
- · 專為 Readers who intentionally buy unrestricted ebooks, power users with e-readers, and privacy-minded buyers who want ownership and multi-device portability. 打造。
- · 最可能的變現方式：Affiliate marketplace。

差異化
為什麼這件事可能失敗
自我反駁——最重要的信任度信號
- 1Readers may love the idea but still buy infrequently, making monetization through affiliate commissions too thin.
- 2Major stores may not expose enough structured metadata, forcing brittle scraping and constant maintenance.
- 3Large retailers could improve DRM labeling, reducing the value of a standalone search layer before the product reaches scale.
證據綜述
AI 如何合成此洞察——無原話引用
The discussion repeatedly returned to discovery friction. Multiple commenters named individual stores that sometimes carry unrestricted titles, while others explicitly wanted DRM status shown before checkout or asked for a single search interface across marketplaces. Several replies effectively crowdsourced a fragmented catalog, which is strong evidence that users lack a canonical, trusted destination.
