What this app is. What it isn’t. What you could build.

One-liner

A fast, no-frills eBook search tool that helps users find and preview EPUBs across multiple libraries and retailers.

Strengths

Fast search results with minimal latency ("Searches are instant, even with thousands of books" - Review #123)
Supports direct EPUB file previews without requiring external readers ("I can open and read the first few pages right in the app" - Review #45)
Aggregates results from major eBook sources like Project Gutenberg, Open Library, and LibriVox ("Covers more free sources than any other app I’ve tried" - Review #78)
Clean, distraction-free interface focused solely on discovery ("No ads, no clutter—just books" - Review #201)
Strong keyword matching for niche genres and obscure titles ("Found a rare sci-fi anthology I’d been searching for years" - Review #310)

Weaknesses

Limited filtering options beyond genre and format ("Wish I could filter by publication year or author nationality" - Review #192)
No offline access to saved searches or book metadata ("Can’t use it on flights because everything needs internet" - Review #304)
No integration with personal reading apps like Readwise or Apple Books ("Would love to sync my favorites to Apple Books" - Review #156)
Some EPUB links lead to broken or duplicate files ("Hit ‘preview’ and got a corrupted file twice this week" - Review #222)
No user accounts or bookmarking system ("I have to re-search every time I want to revisit a title" - Review #401)

Opportunities

Build an offline-first version with cached search results and local book metadata
Add cross-platform sync via iCloud or Readwise to let users save and track favorite books
Introduce advanced filters (e.g., publication decade, language, publisher) to improve precision
Create a curated “Hidden Gems” feed based on user behavior and rare title detection
Partner with indie publishers to offer exclusive EPUB previews not available elsewhere
