AI vs Human: Who Writes Better Review Replies?
The debate is legitimate: can an AI write a review reply that feels as genuine and personal as one a human restaurant owner wrote themselves? To find out, we ran a 6-week blind test across 12 Bangkok restaurants, showing real customers 600 AI-generated replies and 600 human-written replies — without telling them which was which.
What the Data Showed
- AI replies were rated "professional and appropriate" by 91% of respondents vs 84% for human replies
- Human replies were rated "more personal and warm" by 67% — but only when they were actually personalised (many weren't)
- Generic human replies ("Thank you for your visit, we hope to see you again!") scored lower than AI replies in every metric
- AI replies in Thai were rated as natural-sounding by 88% of Thai-speaking respondents
- Response time satisfaction: AI users averaged 4.2 hours to reply; human-only restaurants averaged 31 hours
The Honest Conclusion
AI doesn't replace the best human reply — but it dramatically outperforms the average human reply. The average restaurant owner, juggling dozens of responsibilities, writes replies late, writes them quickly, and often defaults to the same template. AI writes a personalised, on-brand reply within seconds of the review being posted.
The winning approach: use AI to draft every reply, then spend 10 seconds reading and occasionally adding a personal touch. You get the speed and consistency of AI with the warmth of human oversight. Restaurants using this hybrid method scored highest in our study across all customer satisfaction dimensions.
