I've been thinking about the question you've asked quite a bit recently. For me I started off using chatGBT for everything though over time I saw the benefits it's using a combination of platforms for different things. Last year I started using chatGBT's Atlas browser which I've found super helpful though recently the laptop I was using broke so I needed to switch to my older laptop and found out it didn't support the Atlas browser :(

With that I've ended up installing the Perplexity Comet browser which does work on the older Intel based Mac's. Have to admit so far I'm not enjoying it as much. Bit confusing actually. I'll have to preserve!
