Inkwell automatically delivers your Substack subscriptions to your Kindle as beautiful EPUBs, no manual forwarding required. Subscribe to a publication once and every future issue appears on your device automatically. Custom covers, digest mode that bundles everything into one morning delivery, and quick share from your iOS share sheet. Built for people who want to read intentionally, off their phone, on e-ink.

i have a Kindle I love and a pile of unread newsletters in my inbox. the two things never talked to each other. every tool I found either required me to manually forward each email or had a clunky setup that felt more like a workaround than a real product. so I built something that just works. paste a Substack URL once, every future issue lands on your Kindle automatically, beautifully formatted with custom covers. I built Inkwell in my spare time as a solo developer. it started as a weekend project and grew into something 200+ people now use daily. the thing I'm most proud of is the digest mode, which bundles all your subscriptions into one morning delivery that feels like picking up a newspaper. if you've ever looked at your Kindle collecting dust while your newsletter inbox overflows, this is for you. happy to answer any questions about how it works or what's coming next.
