Playable Notes
Any piece, at your student's level. Just ask.
What is Playable Notes?
Playable Notes helps piano teachers turn any piece into a version their student can play. Snap a photo or upload a PDF of sheet music, and it reads it into a real score; then ask in plain English, like "easier left hand" or "put it in C", and it arranges it in about a minute. Hear it, fix any note, and print a clean PDF. New accounts get 50 free credits.

We were essentially paying ten dollars for a premium subscription and the economics worked for us but it just didn't scale as much as we were hoping. We killed it after like a year.
Referral program paid $10/sub, broke even, killed after a year
Lose It!'s referral program paid $10 per converted premium signup. It broke even but never moved the needle. Worse, treated cohorts had lower LTV than untreated — meaning they were probably paying for shares that would have happened anyway. The funnel math is brutal: 5% of exposed users share, 5% of their friends convert. Killed after a year.
If we see you come back and you seem to be focused because whatever classes you're taking this semester are a great fit for Quizlet, maybe we should be refreshing that trial for you because we usually have added a lot of value. If it's been a year since they subscribed, often it's a nice way to say hey here's all the things we've added.
Refresh the free trial for re-engaged returners — but gate it on signal
Treat returning churned users like new users when enough time has passed — re-grant a trial and re-onboard them on the features added since they left. Gate the offer on engagement signals (current usage, time since churn) so you don't fund freeloaders cycling trials each exam season.
There's a play for whatever you're stuck on.
