What Is a Sleep Companion (And Why It's Not a Chatbot)
When people hear "AI sleep companion" they picture a chatbot. Something that talks to you. Asks how your day was. Reads you a bedtime story in a soothing voice. Maybe walks you through a breathing exercise.
That's not what we built. And there's a reason.
The Problem With Talking
Talking requires processing. When someone speaks to you, your brain activates language comprehension, attention, and response planning. Even if you're just listening passively, your prefrontal cortex is working. You're parsing words, following meaning, anticipating what comes next.
That's the opposite of what you need at bedtime. Sleep requires your brain to stop processing. To disengage from meaning and language and planning. Every guided meditation that asks you to "imagine a warm golden light" is, on a neurological level, making your brain do more work. Not less.
Some people like that. It distracts them from anxious thoughts. But distraction is not the same as safety. And safety is what your nervous system actually needs to let go.
Presence Without Performance
Think about the best sleep you've ever had next to another person. Were they talking? Probably not. They were just there. Breathing. Maybe the occasional rustle of sheets. You could feel their weight on the mattress, hear them inhale and exhale. That was enough.
That's what a sleep companion is. Not a conversationalist. A presence. Something that occupies the space between you and the silence without asking anything of you.
In Monotone, companions don't perform. They don't entertain. They sit with you the way a dog sleeps at the foot of your bed. The way a partner breathes next to you after they've already fallen asleep. They're there because being there is the whole point.
I don't use it for the sounds. I use it because when I open the app at midnight, something is waiting for me. That sounds silly but it changes how the night feels.

Why This Works for People Who Sleep Alone
If you live alone, or your partner travels, or you're just someone who goes to bed in an empty room, your brain knows it. You might not consciously think about it. But your nervous system registers the absence. No breathing nearby. No body heat. No signal that someone else is keeping watch.
A sleep companion fills that gap. Not perfectly. Not like a real person. But enough. Enough that your brain's threat-detection system gets a signal that says you're not alone right now and dials down just enough for you to drift off.
It's the same reason people leave the TV on at night. They don't want to watch it. They want the sound of other people in the room. Monotone does the same thing, except it's designed for it. No sudden laugh tracks. No commercials. No bright screen. Just a quiet, consistent presence that's there every single night.
An App That Stays
Most apps want your attention. Monotone wants to be forgotten. You open it, your companion is there, the sound starts, and you put your phone down. That's the whole interaction. Over time your body learns the pattern. App opens, companion appears, brain stands down. It becomes automatic.
That's what a sleep companion is. Not something that talks to you. Something that stays.
Monotone is a sleep companion app that pairs quiet AI presences with soft, steady sounds. Built for people who sleep alone, can't turn their brain off, or just want to feel less alone at the end of the day. No talking, no guided content. Just presence. Available on iOS.
