How it works
Tell it the book. Tell it the chapter. Read.
i.
Choose your book
Pick from the catalogue or request any title — Sonder studies the story and maps its emotional arc, chapter by chapter, in seconds.
ii.
Open to your page
Say where you are. Sonder learns your reading pace once, then quietly estimates where you are in the scene as you read.
iii.
The music follows
As the story turns — tension, tenderness, triumph — the score turns with it. No playlists to manage. No lyrics to intrude.
Ten moods, infinite stories
Music written for the way stories feel.
“The right music doesn't distract you.The idea behind Sonder
It pulls you in deeper.”
