One intelligence layer. Any streaming service. Any device. The music never stops, it just adapts.

Under the hood

The music brain
behind every scenario.

Every scenario above is powered by the same intelligence layer. Composable primitives that any AI agent can use to master music.

Infinite Context

Heart rate, calendar, weather, location, social context, food orders, time of day -- everything flows in. BeatBrain turns it all into a musical scene.

Intelligence Layer

7 knowledge sources, 10 scoring dimensions, energy arcs, harmonic sequencing, taste genome. Every track is scored, ranked, and explained.

Bidirectional

Your agent talks to BeatBrain. BeatBrain talks back. Feedback loops that compound. Every skip, like, and vibe shift makes it smarter.

Composable Primitives

23 MCP tools. Interpret, search, plan, play, feedback, enrich. REST + SSE + webhooks. TypeScript and Python SDKs. Build any music workflow.

For Developers

npm install @beatbrain/sdk

Your agent already knows the user. Now give it the music brain.

agent.ts
import { BeatBrain } from '@beatbrain/sdk';

// Plan a set from any context
const set = await bb.planSet({
  prompt: "girls night, dinner then going out",
  context: { event: "girls_night", friends: ["Sarah", "Mia"] }
});

// Context changes? Music adapts
await bb.updateContext(set.session_id, {
  energy: 0.9,
  mood: "drinks arrived, let's go"
});

In 2 years, nobody will make a playlist.

Their agent will just know. BeatBrain is the intelligence layer that makes it possible.
