Every Moment Has
a Soundtrack.
AI agents run your calendar, your car, your home. They know your heart rate, your schedule, who's in the room. But when it comes to music — the most emotionally intimate digital experience — they're clueless. BeatBrain gives them the music brain. One API, any device, any context.
Use cases
One API.
Infinite experiences.
From personal assistants to smart cars to wedding venues — every product that touches human experience needs context-aware music. BeatBrain makes it one API call away.
Personal AI Assistants
Siri, Alexa, ChatGPT, Claude, Gemini
Your assistant knows you're stressed, it's raining, and you have 45 minutes before your next call. One API call to BeatBrain and it's performing a perfectly paced ambient set that winds down as your meeting approaches. Not a playlist — a living, breathing soundtrack for your life.
// Your assistant becomes a DJ
const set = await bb.planSet({
prompt: "deep focus coding session,
tired but need to ship",
end_user_id: user.id
})
// Adapts as context changes
assistant.on('mood_shift', async (mood) => {
await bb.updateContext(set.session_id, { mood })
})Automotive Intelligence
Tesla, CarPlay, Android Auto
65mph, three passengers, golden hour, highway stretch ahead. The car already has every signal it needs. BeatBrain turns that into a road-trip-energy set that makes everyone in the car feel like they're in a movie. Windows-down anthems that match the speed, the light, the moment.
// Car AI detects road trip vibes
await bb.planSet({
prompt: "highway drive, 3 passengers,
golden hour, windows down",
sensors: { vehicle_speed_kmh: 105,
people_count: 3 },
end_user_id: driver.id
})Smart Home Agents
Home Assistant, Google Home, Alexa
Six guests, candles lit, wine open. Your home agent doesn't ask what to play — it already knows. Warm, sophisticated jazz transitions seamlessly to upbeat as dinner moves to dessert. Ambient intelligence so natural your guests think you hired a DJ.
// Smart home orchestrates the vibe
const set = await bb.planSet({
prompt: "dinner party, 6 guests,
candles lit, wine open",
sensors: { people_count: 6,
location_type: "home" },
end_user_id: home.owner_id
})Fitness & Wellness
Peloton, Apple Fitness+, Whoop, Oura
155 BPM. Peak interval. The music locks to your heart rate and drives you harder. Cool-down starts — the tempo drops with your pulse. Your body and the music become one system. This is what biometric-reactive music feels like.
// Fitness app syncs music to heart rate
await bb.updateContext(session.id, {
sensors: { heart_rate: 155 },
prompt: "peak HIIT intensity"
})Workflow & Focus Agents
Pomodoro bots, Notion, Obsidian
90-minute deep work sprint. Zero lyrics. Steady BPM. Low energy variance. The music doesn't just match your focus — it protects it. Meeting in 10 minutes? The energy winds down so the transition feels natural, not jarring.
// Pomodoro app manages focus music
const set = await bb.planSet({
prompt: "deep focus study session,
45 minute sprint, no lyrics",
energy_curve: "peak_valley",
end_user_id: student.id
})Events & Hospitality
Venues, conferences, restaurants
A wedding planner sets the mood once: 'dinner transitioning to dance floor, ages 25-65, family-friendly.' BeatBrain performs a 3-hour set with perfect energy arcs — dinner jazz builds into dance floor anthems. No DJ hire. No playlist anxiety. No awkward silence.
// Wedding planner sets and forgets
const set = await bb.planSet({
prompt: "wedding reception, dinner
transitioning to dance floor,
ages 25-65, family-friendly",
track_count: 30,
energy_curve: "building",
end_user_id: planner.id
})Gaming & Interactive Media
Unity, Unreal, VR experiences
You enter the dungeon. Low drones. Heart rate climbs. Boss appears — the music explodes. Health drops to 30% — frantic percussion. Victory — triumphant release. Adaptive soundtracks that feel composed for this exact playthrough.
// Game engine syncs music to state
await bb.updateContext(session.id, {
prompt: gameState.biome + " boss fight",
energy: gameState.intensity,
})Retail & Hospitality
Stores, hotels, cafes, spas
Saturday, 9pm, 80% capacity, upscale Italian. BeatBrain reads the room — crowd energy, time, vibe — and performs a set that makes guests order another bottle. Studies show the right music increases dwell time 20%. BeatBrain makes it effortless.
// Restaurant AI manages the soundtrack
const set = await bb.planSet({
prompt: "upscale Italian restaurant,
Saturday evening, nearly full",
sensors: { people_count: 80,
location_type: "restaurant" },
energy_curve: "building",
end_user_id: venue.id
})The evolution of music
From playlists
to invisible intelligence.
Every era of music technology made listening easier. The next era makes it effortless.
The Physical Era
You owned the music.
Vinyl, cassettes, CDs. You bought albums, built a physical collection, and pressed play. Discovery was word-of-mouth, record stores, and radio DJs. The music was yours — but choosing it was work.
The Playlist Era
You curated the music.
iTunes, then Spotify. Suddenly every song was available — but you had to find them. Playlists became the organizing principle. Millions of hours spent searching, saving, sorting. Better than CDs, but still manual.
The Algorithm Era
The platform chose the music.
Discover Weekly. Algorithmic radio. The platform learned your taste from listens and likes. Good for discovery — but context-blind. It didn't know you were driving, coding, or heartbroken. Same recommendations regardless of the moment.
The Intelligence Era
The music performs itself.
Your AI agent knows the context — mood, heart rate, weather, who's in the room, what's on the calendar. BeatBrain gives it the music brain. One API call and the perfect soundtrack materializes on any device running Spotify. No searching. No playlists. No skipping. Music that understands your life.
BeatBrain is the intelligence layer that makes this possible.
Everyone wins
Built for the
entire ecosystem.
For Users
No app. No search. No playlist curation. You just live your life and the music is there — perfectly matching your moment, on your phone, speaker, CarPlay — anywhere Spotify runs. It knows you. It knows this moment. And it gets better every single day.
For Developers
One API call turns any AI agent into a context-aware music engine. Composable primitives for interpretation, search, set planning, and playback control. Auto-discoverable via MCP.
For Artists
AI agents discover deep cuts, not just hits. BeatBrain scores music by context fit — not popularity. Your art finds the perfect listener at the perfect moment, across every device running Spotify — phones, speakers, CarPlay, smart displays. More plays. Better discovery. No gatekeepers.
