Config Files Needed

New in v2.1

Zero config.
Just talk.

Three new capabilities that make Cerebro even easier for non-coders.

Quick Task

Zero Setup

Just describe what you want. No sessions to create, no agents to configure. Cerebro auto-creates the session, picks the right provider, and delivers.

// You say:
"Build me a to-do app"
// Cerebro:
Done. Files saved to ~/apps/todo
📂

Project Reader

No Blind Edits

Before making changes, Cerebro reads your folder structure and file contents. Understands your code first, edits with full context.

Scans directory tree
Reads relevant files
Ignores node_modules, .git
Smart filtering by pattern
🖥️

Visible Terminals

Watch It Work

Each agent task opens a real terminal window showing live progress. See what your AI is doing in real time — no hidden magic.

How It Works

Three steps.
No coding.

From your idea to a working product, all through conversation.

💬
01

You Describe

Tell Claude what you want in plain English. Upload screenshots, share ideas, describe features — just like talking to a colleague.

🧠
02

Cerebro Orchestrates

Cerebro breaks your request into tasks, creates specialist AI agents (Designer, Coder, QA), and coordinates their work automatically.

03

You Get Results

A working product, tested and ready. Cerebro reports back in plain language — no logs, no terminals, just results.

Natural Language

Talk, don't code

Describe what you want the way you'd explain it to a person. No programming languages, no configuration files, no terminal commands.

  • Describe features in plain English
  • Upload screenshots of bugs or mockups
  • Ask for changes naturally — "make the header bigger"
  • Get results explained in everyday language

Agent Swarm

Your AI team,
built by talking

Create specialist agents just by describing what you need. They remember your preferences, delegate tasks to each other, and improve over time.

  • Create agents with natural language — no config files
  • Agents delegate to each other automatically
  • Use starter kits: Web App, API Service, Content Site
  • Add agents from the community marketplace
🧠
Fresh Context
Every task starts clean
🔐
Session Tokens
Resume across conversations
📊
Context Monitor
Auto-handover when needed
Reliability

Never loses
its place

Each task gets a fresh context window — no confusion from old conversations. When you run out of space, session tokens let you continue seamlessly in a new chat.

  • Fresh context per task — no accumulated confusion
  • Signed session tokens survive chat handovers
  • Agent definitions and preferences persist automatically
  • Context health monitoring with auto-handover
