Hmm... I don't know.
You can import data into BookWyrm from GoodReads, LibraryThing, StoryGraph, OpenLibrary and Calibre. It works by exporting a CSV file from these services, and then importing the same file into BookWyrm.
If there's a CSV file export function on Kindle, maybe you could try importing that?
