Frequently Asked Questions

What is a LinkedIn post analyzer?

A LinkedIn post analyzer is a tool that evaluates your post before publishing and predicts how well it will perform. Reactor analyzes hook strength, debate potential, authenticity, and timing to give you a GO/WAIT/IMPROVE verdict with estimated impressions.

How does Reactor predict LinkedIn engagement?

Reactor uses calibrated heuristics trained on real LinkedIn post data. It analyzes your hook (curiosity, emotion, controversy), debate potential, authenticity, content type, and posting time to estimate impressions and engagement.

What is cringe detection?

Cringe detection identifies posts that feel too salesy, cliché, or inauthentic. A high cringe score means your audience may find the post awkward or insincere, which hurts engagement.

What is the debate score?

The debate score predicts how likely people are to discuss or argue about your post. Higher debate scores often lead to more comments and engagement, as controversy drives conversation on LinkedIn.

Is Reactor free?

Yes! Reactor offers 2 predictions/day without signup (demo mode), or 5 predictions/day with a free account. A Pro tier with unlimited predictions and advanced features is coming soon.

Can I use Reactor with Claude Desktop or Cursor?

Yes! Reactor includes an MCP server. Add it to your Claude Desktop, Cursor, or Windsurf config to analyze LinkedIn posts directly from your AI assistant. See the GitHub repo for setup instructions.
