I am basically a script kiddie and Anthropic Claude helped me design a small app for myself that was way beyond my own capabilities and it even went as far as documenting in comments what each bit of the program did for me, to help me understand the logic.

I only have access because I got a free year of Perplexity.ai because I had a paypal account (barf, had to have it to get paid for gig work).

I see it as very useful for anything technical, it helped me through some troubleshooting a hardware issue with my monitor I was having trouble pinning down by browsing forums.

I would never purposely divulge personal info to an LLM, anything that's shared has had personal info stripped.
