I was very impressed with the output. I uploaded a pdf of a webpage and got quick results with actionable information. The information on UX heuristics in the explanations was a wonderful surprise. I feel like this would be a great addition for someone doing audits for clients.
I haven't tried for for ad copy or images yet, as that's not a huge part of what I do, but I look forward to finding out more.
Also, I sent a message and got a quick response, something that is very important to me.
