How it works

Trigger: Google Business Profile — new review

Detect a new review on your Google Business Profile.
AI writes a short, warm reply in the reviewer's language.
Low ratings go to Slack as urgent; others get the suggested reply to post.

Build it

Pick your tool — same automation, step by step.

Copy and paste straight into an n8n canvas (Ctrl+V), or download and use Import from File. Then connect your own credentials and replace every YOUR_… placeholder. AI steps use a Claude model node — swap it for OpenAI, Gemini or Ollama if you prefer.
