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. Freemium: new accounts get 50 free credits, and a free library of 321 piano pieces is included; credit packs are one-time purchases from $10.
