You raise a really important point about the risk of lessening the reading experience. That's something I've thought about a lot. My personal experience while using it has been that it can actually deepen immersion, since I'm able to look up a word or phrase instantly without breaking my flow and switching to a browser.

You're absolutely right that this is a new kind of reading experience powered by LLMs, and there are bound to be some downsides. I hope it's an interesting experiment, and I'd be thrilled if you gave it a try.

Thanks again for the valuable perspective!
