I built an AI voice agent for local businesses that answers calls 24/7 — €99 one-time, no subscription

by David

Hey IH 👋

I'm a solo developer from Spain. I built Vokio — an AI voice agent that answers real inbound phone calls 24/7 for local businesses (restaurants, dental clinics, barbershops, etc.).

The problem I kept seeing: small businesses lose 30-40% of inbound calls because nobody picks up after hours, during lunch, or on weekends. The caller doesn't leave a voicemail — they call the competitor.

Hiring a receptionist = €2,000-4,000/month. Not realistic for most local businesses.

So I built Vokio:

Answers every call in under 3 seconds
Handles FAQs, bookings, and information in Spanish (and other languages)
Remembers returning callers
Post-call analysis with Claude AI
6 industry templates (dental, restaurant, barbershop, etc.)

Tech stack: Python + Flask + Vapi (Custom LLM) + Claude Haiku + Azure TTS + Deepgram STT + SQLite

Sold it as a one-time purchase on Gumroad for €99 — no monthly fees, no lock-in. Launching on Product Hunt September 1st.

Happy to answer any questions about the build!
