Tack så mycket för att du försökte hitta en lösning. :- )
Definitely, the AI popup is helpful because it also shows synonyms, and that helps to map out more mental connections. The etymology is also very useful.
I like your approach very much. But by constantly querying a LLM, or TTS, I'm also worried about the energy usage/environmental impact. I don't know if I'm the only one who cares about those things in 2026, but I do. Of course, it's damn efficient to use these features. And in some cases, 1 click to highlight a word can save 20 minutes of frustration and naturally enable faster learning. But doing that 100 times adds up, and if given free reign, I can absolutely do that. So I do want to voice that concern, even though I'm a dunce when it comes to AI and web development and whatnot.
