What if you actually did it?
Butterfly takes one real choice you're turning over: a move, a leap, a "what if" you can't quite shake, and writes the life that might follow. Chapter by chapter, entirely on your phone.
One choice. A whole other life.
Maybe it's moving to Italy. Opening the bakery. Taking the job you turned down. Butterfly doesn't just answer "what if." It lives it out, one quiet chapter at a time, and lets you steer where it goes next.
- 1 Name the fork in the road. Tell Butterfly the choice you're wondering about, pick a tone and a setting, and it writes your first chapter.
- 2 Hit a crossroads. At the end of every chapter, the story pauses and hands you the wheel: you choose what your other self does next.
- 3 Watch it grow. The timeline branches out with every choice, becoming a whole alternate life that's unmistakably yours, and no two readers get the same story.
Nothing about your imagined life leaves your phone.
This is the part we're proudest of. Every chapter of your story is written on-device, using Apple Intelligence where it's available, or a small downloaded model as a fallback when it isn't. There's no server writing your story, no account required to start, and nothing about the life you're imagining is ever sent anywhere. It's private the way a journal is private.
"Not a chatbot. Not a quiz. A story about the you who said yes."
Start free. Stay as long as you like.
Every story opens with a handful of free chapters, so you can feel out whether this particular "what if" is worth following. If it is, two simple options carry it further: both one-time purchases, no subscription.

Butterfly is a small, independent project, built the way we'd want to use it ourselves: quiet, personal, and not trying to hook you. If you have thoughts, questions, or just want to talk about your favorite alternate life, we'd love to hear from you.
