I’ve been using duck.ai recently myself and quite like it. My only complaint with it is that the chats have a length limit, so if you’re working on complex projects you can run into those limits pretty quick. I use it for worldbuilding for a novel I’m working on and I have to use chatgpt for thematic stuff because it has a better memory, but otherwise it’s great for quick/small things.
To be clear you don’t have to get that technical to read non-Amazon books on your kindle… I’ve owned 2 different kindles over the course of about 15 years and literally never bought an ebook from Amazon. Just gotta know where to get them (libgen) and how to use them (calibre.)
A cheap ereader would be nice, but I’ve kinda had to go the opposite direction; my eyes weren’t great to begin with and have only gotten worse with age, so I need a larger screen. I do very little reading (in general, not of books specifically) on my phone because it’s too small and I have to zoom in and pan around all the time, etc.
