Quickstart

There are two ways to get started with Reactor. Pick whichever fits how you work.

Option 1: Start in the app

The fastest way in, no setup beyond signing up.

Sign up at reactor.tools. Solo is free forever, no card.
Onboard: name your company. Reactor finds your site from your work email domain and seeds the engine from it: voice, audiences, competitors, positioning. Fix what it got wrong; it remembers.
Configure your engine: refine the seeded voice, audiences, and positioning, or click ✨ to have AI draft any section from your site.
Plan a project: pick a direction and a two-week project assembles on a canvas: briefed, dated pieces across your channels. Generate them from the board.
Publish or schedule: post now, or drag pieces onto days and let the calendar ship them.

→ Continue with Onboarding, then Configure your engine.

Option 2: Hand it to an AI agent

Prefer to drive Reactor with AI? Connect the Reactor MCP server to your agent (Claude Code, Claude Desktop, Cursor, and others) and hand it the setup skill. The agent installs the server, helps you connect your services, and fills in your engine for you.

Add the MCP to your client:

npx @reactor-tools/mcp install --key YOUR_API_KEY

Then point your agent at the setup skill and ask it to get you started.

→ See Build with AI and Hand setup to an AI.
