@Preuve AI - AI Startup Business Idea Validator

So I tested out Test Your Idea, and it actually works pretty well. You put in your idea, wait a minute, and it shows you the stuff you've been missing. Got some decent pivot suggestions that helped me refocus from a tiny niche to something way bigger. Saved me from probably wasting a few months in the wrong direction if you're actually gonna build something, not just daydreaming about it

The process of actually creating a bot is so simple, even the free chatbot. Although the mobile compatibility was issue before, it seems to have been resolved by now.

Had several issues with app, beginning with a refresh needed to find the upload (figured out while waiting for help desk). Relatively straightforward conversion, rearranged fields, merged integer and text field. Conversion was Ok on first 30 lines and 2 pages, second 25 lines needed more manual editing. Was going to rate lower, tried Parseur was even worse.

I tried other tools aswell, this was the only accurate. Other ais didn't even get the country right. Compared to the others it had the advantage that I could specify the area in which the location was. I only tried it once so far but I am satisfied.
