Questions & Answers

As answered by people managing SEO.ai and ReplyStack.

What's the story behind your product?

ReplyStack's answer:

ReplyStack was born from a simple frustration: existing review management tools either cost hundreds of dollars per month or only work with a handful of platforms. After seeing local businesses struggle to keep up with reviews scattered across Google, TripAdvisor, Booking, and Facebook, I built a solution that works everywhere — by combining a lightweight Chrome extension with a centralized dashboard. No complex integrations, no enterprise pricing, just a practical tool that helps SMEs protect their online reputation.

Which are the primary technologies used for building your product?

ReplyStack's answer:

Backend: Laravel 12 (PHP 8.3+) with Sanctum authentication Frontend Dashboard: React + TypeScript + Vite + Tailwind CSS Browser Extension: Plasmo framework (Chrome & Firefox) AI: Claude API by Anthropic for response generation Database: MySQL 8 with Redis caching Infrastructure: Railway (hosting), Cloudflare (DNS/email)

Who are some of the biggest customers of your product?

ReplyStack's answer:

ReplyStack is currently in early launch phase. We're onboarding our first customers from the restaurant and beauty salon industries in France.

What makes your product unique?

ReplyStack's answer:

ReplyStack is the only review management tool that combines a Chrome extension with a SaaS dashboard. This hybrid approach lets businesses respond to reviews on platforms that don't offer APIs — like TripAdvisor, Booking.com, and Yelp — something competitors simply cannot do. Instead of expensive API integrations or risky scraping, our extension works directly in the browser where business owners already manage their reviews. It's legal, reliable, and works everywhere.

Why should a person choose your product over its competitors?

ReplyStack's answer:

Affordability: Enterprise solutions like Birdeye ($299/mo) and Podium ($399/mo) are out of reach for most SMEs. ReplyStack starts free and scales to just €79/month.
Universal platform coverage: Most competitors only support platforms with APIs. ReplyStack's extension approach means we work on TripAdvisor, Booking, Yelp, and any platform where you can manually respond.
Self-service simplicity: No sales calls, no demos required. Sign up, install the extension, and start responding in minutes.
Personalized AI responses: Our Response Profiles ensure every AI-generated reply matches your brand's tone and highlights your business strengths — not generic templates.

How would you describe the primary audience of your product?

ReplyStack's answer:

Small and medium businesses that depend on online reviews but lack the time or budget for enterprise reputation management tools. This includes restaurant owners, hotel managers, e-commerce sellers, beauty salon operators, healthcare providers, and auto repair shops. Our typical user manages 1-5 locations, receives reviews on multiple platforms, and wants to respond professionally without spending hours each week on it.
