Coincidentally, it took only 5 minutes to create a domain appraisal tool last night using ChatGPT and it's significantly better than all of the existing ones on the market right now.
Anyone can do it:
Just copy-paste* the top domain sales into it, and then ask it to estimate appraisals based on that data.
Done!
* Caveat: You can't copy and paste from NameBio, but you can take screenshots and upload those to ChatGPT until @Michael's brilliant mind comes up with a way to outsmart AI's OCR.
Great idea with a lot of potential! It should provide some humorous justification as well e.g. "Your domain isn't worth that much but maybe it can be traded in next year's White Elephant event!"
