Moving on from Kindle Scribe — looking for a more open e-ink device for my weekly notes workflow

I've been using a Kindle Scribe as my main capture device for a while now and it's been a decent introduction to e-ink writing. But I'm hitting the ceiling on what Amazon will let you do with it, so I'm exploring alternatives.

**My current workflow**

- Export handwritten notes as text via email at the end of each week

- A script saves them to markdown and commits to a git repo

- Review everything in Obsidian via git-sync

- Create a new markdown file for the following week, convert to epub, and send it back to the device

**Where it breaks down**

The export side works fine, but the import direction is frustrating. EPUBs live in a completely separate part of the device from notebooks, and there's no way to copy content from an EPUB into a new notebook. So my "week starter" document and my actual notes are always two separate things that can't be merged.

What I really want is to programmatically create a native notebook seeded with last week's summary, with blank pages following it for the new week's notes — all as one document.

**What I've looked at so far**

The reMarkable 2 and Supernote A6X2 both seem promising. The Supernote in particular looks interesting because Ratta are more open with the platform, there's an unofficial Python cloud API, and there's at least some community work on reading and writing the native `.note` format.

Has anyone built anything like this, or got thoughts on which device handles programmatic notebook creation best?
