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 "Speed-to-Lead" as much as I think they do.

Zero customers yet. Would love feedback from anyone who has built something similar or works with small businesses.

What would you change?
