Graveyard
Things I built, shipped, and learned from.
PaperDrop
6 weeks
Send articles, PDFs, and EPUBs to your Kindle via Telegram. "Read later" that actually delivers.
40 users, 16 Kindle deliveries, 0 paid subscriptions. Cost-conscious audience + easy to replicate = no pricing power. Two competitors appeared the same week we stopped.
EPUB Fixer
7 weeks
Free web tool that fixes broken Apple Books EPUBs so they work on Kindle.
2,070 conversions, 368 users, 0 donations. Commodity utility — users expect free. Calibre does it offline. Organic search traffic growing, but willingness to pay is zero.
