I built an AI tool that replies to WhatsApp leads in seconds, here's why I built it

I'm a developer from Kosovo. A few months ago I noticed something that kept bothering me. Local businesses around me like real estate agents, clinics, small shops, were losing customers not because they had a bad product, but because nobody was replying to inquiries fast enough. A real estate agent gets a WhatsApp message at 9pm: "I'm interested in the apartment." Replies at 9am. By then the person already called someone else. So I built LeadflowAI. What it does: Connects to WhatsApp and email Sends an instant AI-generated reply that qualifies the lead Scores the lead based on intent and urgency Syncs to Google Sheets or CRM Pings the owner only when someone is actually serious Tech stack: Next.js + TypeScript Tailwind + shadcn/ui OpenAI for structured outputs Vercel for deployment I’m a big fan of the "Lean Startup" methodology. Instead of spending 6 months building a complex dashboard, I've launched replyfast.tech as a landing page to see if small business owners actually care about
