This is pretty cool. I didn't know that I can actually see what created the the text I was analyzing. The extra token feature unlocks that, it is awesome.

Just downloaded it for the first time thanks to your coupon code, I've got a big discount :) But what I love is how easy it is to use it, much better than gptzero and zerogpt, and explanation is so far amazing. I'll try to write another review after a month. Thank you guys for this cool tool!
