companion.ink | AI e-reader

Kindle doesn't have a native ChatGPT or Claude app, but that doesn't mean you can't use AI while reading. companion.ink brings AI chat directly to your Kindle through its built-in web browser, with no downloads or installations required. Ask questions about your books, explore characters and themes, look up unfamiliar concepts, or dive deeper into ideas that spark your curiosity, all without reaching for your phone and getting distracted by notifications, social media, or other apps.
