I created a landing page for Test my Title: https://www.baybridgebio.com/test-my-title.html
Originally I was going to try to write a functional MVP in one day, but I got stuck on a few technical things and ended up not getting the MVP done.
I typically spend too much time coding before talking to users, so decided to just start emailing people the landing page, and only go back to coding if there was enough interest.
