The engine

Show two. Pick one. Learn everything.

Every Bibbly product runs on the same idea: pairwise comparison powered by Bayesian learning. You just pick.

1
Compare
We show you two options side by side - could be baby names, could be outfits, could be grandparent nicknames. You pick the one you like better.
2
Learn
A Bayesian model updates your preference profile across phonetics, style, origin, formality, and more. Your rankings get sharper with every pick.
3
Discover
After 15-20 picks, you have a ranked list of what you actually like. Keep going and the rankings tighten up.
Story Box
Your family becomes characters in real board books.

We made our daughter Mara into a happy dinosaur. I'm a bear. My wife is a fox. My mother-in-law is a cat named Gigi. Then we generated board books where Mara goes on adventures with her family - in a crayon-on-cream art style that stays consistent across every book. Peek-a-boo stories now, sharing stories when she's older. Printed, shipped, and built for teething. That's the Story Box.
