Show HN: ZinFlow – Convert web articles to ePub for Kindle and e-readers

2 morphinewan 0 5/27/2025, 8:40:48 AM wanyi.dev ↗

Built this after getting frustrated with cluttered online reading. Uses a cloud-based "Smart Distillation Engine" to extract clean content from web pages and convert to EPUB. Started client-side but moved to server processing for 95% accuracy on mainstream sites. Recently added multi-article compilation and dedicated email servers for reliable Kindle delivery. Happy to answer questions about content extraction challenges or building sustainable indie apps.
