Without a doubt Petal is the most comprehensively helpful ai for analysing, comparing and paraphrasing multiple papers or websites etc. it’s table feature totally rocks for gathering citations and will answer you]r questions in a table containing your choice of docs - it then mines each uploaded doc for answers to your questions. The multi-doc lit review writer it’s very cool once you get the hang of it’s. Honestly, there are so many things to love in this ai - I’m truly surprised it’s isn’t more widely used … it mines your documents thoroughly and finds all kinds of helpful insights. I use it by preference.

@The Prompt Challenge

Great way to improve you prompting skills through daily exercises. This should be implemented in schools, would really help students. Can also see it being really valuable for adults. Not just for prompting, but for articulation in general. Also made a video about it: https://www.youtube.com/watch?v=A8ZRJgLCFy8
