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
A third of Americans 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.
We wanted an app that could be a calm, conversational, and supportive voice to gently guide us back to sleep when we were 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 voice-AI or sleep and are interested in being a part of Sotto's vision—please reach out. We’re just getting started.
What beta testers are saying
“I like that it just picks something for me, however I'm feeling. I don’t have the brainpower to choose in the middle of the night.”
“It’s nice that it switches things up. Some nights it's a longer guided meditation, other nights I just need a quick chat to clear my mind before falling back asleep.”
“I used to end up browsing sleep apps for a while and somehow wind up on Instagram. This would help keep me off my phone.”

How is Sotto different from other sleep apps?
Most sleep apps are built for bedtime routines or long-term sleep training programs. Sotto is designed for when you wake up in the middle of the night, and are too frustrated to deal with a complex app. Sotto responds immediately, adapts to how you're feeling, and doesn't require navigating menus or looking at a bright screen menus.
What sleep techniques does Sotto use?
Sotto uses clinically-proven methods including CBT-I protocols (cognitive behavioral therapy for insomnia), Yoga Nidra guided mind-body relaxation (NSDR), sleep meditation, progressive muscle relaxation, breathwork, body scans, cognitive reshuffling techniques, sleep sonic soundscapes, and even boring bedtime stories. All are endorsed by sleep specialists.
Can I choose different voices?
Yes! Sotto will offer 4 comforting voices (male and female) so you can find the one the one that is most soothing and calming for you.
What if I'm somewhere I can't talk or play sound?
No problem. If you’re in a quiet space like an airplane or shared room, just use headphones. Sotto will still guide you with voice, and you can reply with simple taps—like “yes,” “no,” or selecting an option.
What does “Sotto” mean?
Sotto comes from sotto voce—an Italian phrase meaning “in a quiet voice.” It reflects the calm and comforting tones of our AI voices.
Is my data private?

How much will it cost?
Sotto will be free during early access. After that, we'll offer an affordable all-inclusive monthly plan — without the annoying ads, upsells or yearly contracts.
