The highest-end model in the Kindle line is the Kindle Scribe, which combines both an e-reader and a digital notebook for composing journal entries, taking notes, making annotations, accessing and editing PDFs, and more. Some premium models, like the Amazon Kindle Paperwhite Signature Edition (11th Gen), include Wi-Fi access built-in so you can surf the web and enjoy assistive features while reading, like being able to look up words and passages, get definitions, and more.
