How to automatically reply to Google reviews with AI

Step-by-step guide to building a system that detects new Google reviews and generates personalised AI responses automatically.

Why responding to reviews matters

The data is clear: businesses that respond to their Google reviews have 35% more conversions than those that don’t.

The problem: responding to every review takes time. And most local businesses simply don’t do it.

The solution: automate it with AI.

How the system works

The full workflow has 4 parts:

1. Detecting new reviews

We use the Google Business Profile API to monitor new reviews every hour. When a new one appears, the automation workflow triggers.

Data captured:

  • Review text
  • Rating (1–5 stars)
  • Author name
  • Date

2. Sentiment and context analysis

We send the review to the Claude API with a specific prompt that:

  • Determines whether it’s positive, negative or neutral
  • Identifies the main topic (service, price, staff, product)
  • Detects if it mentions employee names or other specific details
  • Evaluates whether an urgent response is needed (1–2 star reviews)

3. Generating a personalised reply

Based on the analysis above, we generate a response that:

  • Positive reviews (4–5 ⭐): Genuine thanks, references specific details from the review, subtle CTA (“we look forward to seeing you again”)
  • Neutral reviews (3 ⭐): Thanks + acknowledgement of the issue + commitment to improve
  • Negative reviews (1–2 ⭐): Empathy, acknowledgement, request to make direct contact to resolve the issue

The tone of each reply adapts to the tone of the original review and the business profile.

4. Publishing or human review

This is where the workflow splits:

  • Positive/neutral reviews: Published automatically via API
  • Negative reviews: The proposed reply is sent to the owner via Telegram/email for approval before posting

This split is key for sensitive reviews where an automatic response could make things worse.

What you need to implement it

APIs and services:

  • Google Business Profile API (access via Google Cloud)
  • Claude API (Anthropic) or OpenAI GPT-4
  • Automation platform (self-hosted or cloud)
  • Telegram Bot or email for notifications

Estimated cost:

  • Automation infrastructure: €8–15/month on a VPS
  • Claude API: ~€5–15/month for a business with 50–100 reviews/month
  • Total: under €30/month

Implementation time: 2–4 hours for a technical setup. For non-technical owners, that’s where we come in.
