Your phone already knows
how you sleep.
Now it does something about it.

You charge your phone every night. You place it on the nightstand. It sits there for eight hours doing nothing. DreamBreeze turns those hours into the most useful part of your day. Four AI agents, zero hardware, fully on-device.

Act I · The Problem

During REM sleep, your body cannot regulate its own temperature.

You spend one third of your life asleep. That is twenty-six years. For most of those years, you are too hot, too cold, tangled in sheets, or woken by a fan running at the wrong speed.

3-5 Fan adjustments per night the average sleeper makes

Those are only the times you actually wake up. Dozens more micro-arousals you never remember.

Smart sleep tech is a $30bn category. Most of it costs $300+ in hardware. Wearables, smart mattresses, climate sleepers, sensor pads. Ninety-five percent of the world that already owns a phone gets nothing.

40+ Times per night your body's thermal needs change

A binary fan, on or off, cannot follow that curve. Nobody is solving this. Until DreamBreeze.

Act II · One Night, Watched

A full night, compressed into sixty seconds.

Place the phone on the mattress. Go to sleep. The accelerometer reads posture. Edge AI estimates the stage. Four agents negotiate. The fan, the sound, the wake-up window all adapt to the body underneath.

10:30 PM

Bedtime. Fan starts low. Pink noise fades in.

11:15 PM

You roll to your side. Fan adjusts down. Sound deepens.

12:00 AM

Deep sleep detected. Fan drops to a whisper. Brown noise.

02:30 AM

REM cycle. Thermal agent raises fan, your body cannot self-regulate.

04:00 AM

You shift to prone. Posture agent adapts instantly.

06:15 AM

Light sleep. Energy agent begins gentle wake sequence.

06:45 AM

Good morning. Cognitive readiness score: 82 / 100.

Act III · The Product

Four agents.
One blackboard.
One quiet decision per second.

DreamBreeze does not use a single algorithm. Four specialised agents collaborate over a shared blackboard. They do not take turns. They negotiate.

Agent 01

Posture Agent

Watches: accelerometer · Controls: fan speed

Back sleepers need more airflow than side sleepers. Prone sleepers need the least. Real-time classification across supine, lateral, prone and fetal.

Agent 02

Thermal Agent

Watches: weather + circadian rhythm · Controls: temperature profile

Cross-references outdoor temperature, humidity, and your body's natural thermal dip at 3 AM. Five temperature cycling profiles, weather-aware via Open-Meteo.

Agent 03

Sound Agent

Watches: sleep stage · Controls: noise type and volume

Pink noise to fall asleep. Brown noise for deep sleep. Gradual fade during REM. Real-time synthesis via Web Audio API, no sample files, zero latency.

Agent 04

Energy Agent

Watches: Two-Process Model · Controls: wake sequence

Borbely's homeostatic Process S plus circadian Process C. Fourteen-day rolling sleep debt, cognitive readiness score, twenty-minute gentle arousal window.

Act IV · The Promise

Every byte of inference happens on your phone.

All accelerometer data, all posture classifications, all sleep stage estimations, all agent computations, all audio generation. None of it leaves the device.

Only encrypted sleep summaries are stored, and only if you opt in. The privacy vault lets you download, delete or inspect every byte we have.
