The addition doesn't really bother me because Calibre is already full of features that seem utterly useless, so I trust its author to add new stuff without ruining the parts that are useful to me. Still, does anyone actually use "ChatGPT bolted onto the ebook reader" type features for anything besides cheating on school assignments? Lack of web search tools makes them suboptimal for asking clarifying questions or getting recommendations. Makes some sense on a Kindle where you can't exactly alt-tab to ask ChatGPT directly, not so much in a desktop application.

Not to say that there's no use case (I'd be interested to try a LLM-aided notetaking tool), just that adding a chat box is hardly a feature.

Its useful for answering questions related related to back references. eg who was this character if you're reading a novel with too many of these.

Oh true, that actually sounds useful. I often just avoid that kind of novel because I'm terrible with names.
