I've been using chat GPT pretty hard for the last year. I've dabbled in Claude. Mostly we've used chat gpt for writing quotes to copy and paste in to jobber, and we coded a website for our inventory. Claude does help with longer articles but I haven't tried to move all our stuff over because chat gpt has so much data.
One thing I like more about chat gpt is the voice to talk feature lets you talk for a long time while claude it stops you. I hate having to keep watching my words come out and then it randomly cut you off and you have to hit record again. I'm a bit of a talker when it comes to AI.
