Here's my idea for an AI-based speed dating site/app. You fill in the basics (about you and your preferences), plus 5 things that are important to you in life, plus 1-2 things you want to absolutely avoid (ex, smokers), your availability and that's it.

In the background, the AI matches you and sets you up for a quick coffee date at a location that's not far from either person. Twist: every single person actively looking for a relationship in each particular city must be on the site (aside from self-reporting, I haven't figured out how this will be done).

Essentially, you don't peruse the app, you just receive when & where notifications and then go have a 5-minute coffee to see if you have chemistry, which no current app can actually tell you.
