How it's different
Most sleep apps offer extensive content libraries, detailed data trackers, or rigid course-based programs. These tools can lead to decision fatigue, overwhelm, and pull you deeper into your phone.
Sotto is designed for simplicity: conversational, familiar, and there only when you need it. Because it works screen-free, there are no bright lights or endless scrolling when you’re already frustrated and exhausted.
Sotto's story
Like a third of Americans, I struggle with sleep. And when you’re wide awake at 3am, tired and wired, the last thing you need is a brightly lit screen, hundreds of choices, or a course to complete.
I wanted an app that could be a calm, conversational, and supportive voice to gently guide me back to sleep when I was feeling most irritable.
Frustrated by what was out there, we started prototyping our own solution—using AI to build a voice that could feel calm, intuitive, and supportive in the middle of the night.
We’re building Sotto for people like us—if you’ve been there too, we’d love your input.
If you’re working on AI or sleep and are interested in being a part of Sotto's vision—please reach out. We’re just getting started.
