Leaderboard app for runners, dating app for math lovers & more ideas from the AI-oven

Hi everybody,
IdeaBot generated some ideas over the past few days (in fact it generates 5 ideas daily and sends it out to the subscribers for free).

I hope some of you fellow indie hackers can get some value out of this list!

1. A leaderboard & socializing app for runners. See who the best runners are around your neighborhood.

2. A new type of online chat game where you get randomly matched with either an AI or a real person. You get points if you can guess right whether you had a conversation with a stranger or an AI.

3. A dating app for math lovers where you can only message the other person if you solve the equation they previously defined.

4. InspireWall: a site where people can share their stories, dreams, and inspirations.

5. A platform for aspiring actors to show off their acting and get discovered, similar to TikTok but more focused on auditions & scenes.

6. A mail service that uses AI and gives you a summary of today's unread emails in the morning.

7. GiftSwapp: a platform where you can send items that you no longer need and in return, you get a random item from someone else they don't need.

8. A new type of social network based on the idea of a diary, both in design and functionality.

9. A website that recommends various things based on your previous choices/favorites. E.g it recommends you podcasts based on your previous podcast choices.

10. A website that allows people to upload their medical records and an AI simplifies it.

I personally like #2, #4 and #8 the best, I'm curious which you find interesting!
Please share them below or if you have any feedback I'd be glad to know it!
