I've been using Readwise (and Reader) which have been great, but it's rather expensive.
I'd love to be able to send an arbitrary article to Feedi like I can with Reader, but also would love to sync highlights back from my kindle.
Going to lurk the repo, cool stuff!
Trouble was, the location was in the Kindle's "Loc" format which is nontrivial (at least to me at the time) to connect to specific text in the document.
I'm sure someone's probably worked this out by now?
Update: yes, at least 160 projects

Amazon doesn't expose a direct API for highlighting, and Readwise for example does a little "hack" where you use their browser extension to redirect to the Kindle highlights page and I think they just slurp up the authenticated API requests.
This is set as part of the DRM, so be careful that you are really saving the data you want. I went deep into a book highlighting things before I noticed this limitation.
It obviously does not affect files without DRM.
See my other comment above.
