How Brain works

How Brain Works

Intelligent task orchestration that thinks for you

You Give One Command

"Build a React dashboard with authentication" — that's all you need. No detailed instructions, no micromanagement.

🎯

Conductor Analyzes & Plans

The Brain's Conductor agent breaks down your request, identifies required steps, and delegates tasks to specialized agents automatically.

⚙️

Agents Execute in Parallel

Multiple agents work simultaneously. Senior Dev writes files while Bug Hunter validates completed ones. Faster than any sequential AI tool, in any language.

4

Complete Project Ready

Get production-ready code with proper structure, error handling, and documentation, without babysitting the process.

Built-In Development Environment

Code, run, and preview, all in one place

Real Terminal

Full WebContainer-powered terminal with Node.js support. Run npm install, start dev servers, execute scripts, all in-browser.

$ npm install
added 247 packages in 3s
$ npm run dev
Server running on http://localhost:3000

Live Preview

Instant preview of your apps. See changes in real-time as agents write code. No external tools needed.

localhost:3000

Zero configuration. Brain Mode automatically detects project type (Node.js vs static) and runs the appropriate preview. Just focus on your idea.

Meet the Agents

Four specialized AI minds working in parallel, across every language and framework

🚦

Conductor

Orchestrator

The strategic mastermind. Analyzes your request, detects the tech stack, breaks it into parallel tasks and coordinates every agent, so nothing is built out of order.

📐

Architect

System Designer

Designs the full project structure before a line of code is written. File hierarchy, component breakdown, dependency graph, tailored to your exact language and framework.

💻

Senior Dev

Code Writer

Writes clean, production-grade code in 20+ languages. Handles complex logic, respects idioms of each language, and runs real-time lint validation on every file it creates.

🐛

Bug Hunter

Quality Assurance

Catches errors before you do. Traces runtime failures, fixes broken imports, validates cross-file consistency, and keeps iterating until the project runs clean.
