Which latest AI related tool/product intrigued you most?

I have some tool in mind that with little improvement can be really useful. But I'm going to be little bit biased here and say https://www.askcorpora.com/ is top of list.😅 but many more product has arrived in the AI space some very basic but some really trying to focus on solving a specific problem. These tools are little early but some have real good potential. which tool made you think, wait... this could be something?
