I bought it just yesterday but i'm loving it, love the prompt enhancement and the word cap (otherwise it'd bee to long to compare the answers), after a small use i immediately upgraded to the upper tier. I find it to be much more usable than chat playground, thanks to the word cap.
I'd love even more if it added:
- a function for summarizing the answers with a recap of the differences by the various models (in that case i'd probably choose to remove the said word cap);
- a function like claude projects/gpts.
