David Carr — creator of Braindex
Hi, I’m David. Really, genuinely — thank you for joining us on this journey! Braindex is still in its infancy, and every person who signs up, plays, shares their scores, or sends a note makes a huge difference. We’re slowly growing a small, loyal community of people who want to have fun and get a little sharper at AI every day. That’s the goal: have fun & upskill together.
I read every piece of feedback personally, and I’m committing to iterating on the app every week — new words, new game modes, app improvements — based on what you tell me. If something feels off, or you’ve got an idea, please do let me know! It really does shape what gets built next.
A little about me for those who might not know me: I previously created Pi-Squared & MovieToons, and Braindex is now my latest project. It came out of two things I love — education through competitive gamification, and the daily-game habit. I wanted to put those together to help people feel less behind on AI, one tiny daily session at a time.
So — thanks so much for being here early. I really appreciate it!
