@EchoRead: AI Reading Notes

Decent if you have a bunch of highlights sitting in your kindle that you never go back to. It pulls them in and groups them by theme which is honestly more useful than I expected. Wish it worked better with PDFs though, that's where I do most of my reading and the import was a bit hit or miss for me. Still gonna keep using it for the kindle stuff.
