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 and start your free trial.
Onboard — name your company, name your engine, and optionally add your website so Reactor can tailor your prompts.
Configure your engine — add your voice, audiences, and positioning. Write them yourself, or click ✨ to have AI draft them from your site.
Generate — give a topic, pick channels, and Reactor writes a native draft for each one.
Publish or schedule — post now, or drop it on the calendar.

→ 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 -y mcp-remote https://app.reactor.tools/api/mcp --header "Authorization: Bearer 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.
