Kindle Context Clipper от Sébastien Stecker

This extension allows for a user of Kindle Cloud Reader to download their annotations (words, passages, etc) including the surrounding context: the previous sentence, the current sentence and the next sentence. Opening a book in the Kindle Cloud Reader allows to open the extension, where clicking on the "Start" button will read the annotations in the book. You can then download a CSV file at the end.

The goal of this extension is to make it easier for language learners to create flashcards or exercises with their annotations, which will include a proper context. This functionality is not provided by Amazon.
