Do you feel like elaborating any? I'd love to find more uses. So far I've mostly found it useful in areas where I'm very unfamiliar. Like I do very little web front end, so when I need to, the option paralysis is gnarly. I've found things like Perplexity helpful to allow me to select an approach and get moving quickly. I can spend hours agonizing over those kinds of decisions otherwise, and it's really poorly spent time.

I've also found it useful when trying to answer questions about best practices or comparing approaches. It sorta does the reading and summarizes the points (with links to source material), pretty perfect use case.

So both of those are essentially "interactive text summarization" use cases - my third is as a syntax helper, again in things I don't work with often. If I'm having a brain fart and just can't quite remember the ternary operator syntax in that one language I never use....etc. That one's a bit less impactful but can still be faster than manually inspecting docs, especially if the docs are bad or hard to use.

With that said I use these things less than once a week on average. Possible that's just down to my own pre-existing habits more than anything else though.
