Passages – Article to E-Book Converter

A web app that saves articles from the web and converts them into beautifully formatted ebooks optimized for e-readers. Users save articles via browser extension, organize them into collections, and download as polished ebooks that actually look good on e-ink screens. Target users are voracious readers and e-reader enthusiasts who hate poorly formatted web content.

E-reader ownership has grown steadily alongside the broader "slow media" and digital minimalism movements, and there's genuine frustration among Kindle and Kobo users with tools like Instapaper and Pocket that produce mediocre EPUB output. Instapaper is the closest substitute, but it's been neglected since Pinterest acquired and then divested it, leaving real room for something that actually prioritizes e-ink typography. The $500–2k/mo revenue band is honest for a niche productivity tool — a small subscriber base at $5–8/month gets you there without needing scale, and conversion from free to paid is plausible given the clear pain point. The biggest risk is that the audience, while vocal online, is small enough that organic ceiling is low and paid acquisition economics won't work, leaving the product stranded below meaningful revenue.
