I wrote a service (Google Cloud Run as the backend, with Telegram bot as the frontend) to generate readable ePub from URLs and send directly to e-ink readers. It was originally wrote for reMarkable 2 (using reMarkable cloud), I recently added support for Kindle (by using the send-to-kindle emails). The code is at https://github.com/fishy/url2epub https://github.com/fishy/url2epub and I blogged about the recently added kindle support at https://b.yuxuan.org/url2epub-kindle https://b.yuxuan.org/url2epub-kindle. I'm open to suggestions on what other e-ink platforms to add, as long as they have a reasonable cloud API. I'm also looking for a good e-ink platform to move to personally, as it becomes apparent that reMarkable really doesn't want third parties to use their proprietary cloud "API".
