I think right now I have Claude, ChatGPT, MidJourney, and Perplexity. I guess that's not quite $100 now but I used to do Gemini, too.

Personally:

Perplexity has replaced Google searches for me – basically looking things up

ChatGPT/Claude is what I use for generating code (I'm not a programmer but I like scripting tasks at work)

Claude I think is better at writing than ChatGPT

MidJourney is $10 and I like it best for image generation which I do for work and like to keep it around.
