SantaCalls.ai

Hey Product Hunt! 👋 I'm Brian from LEMA Logic on the Isle of Man. SantaCalls started as an entry for our local AI Meetup's Christmas competition – and ended up talking to kids in 50+ countries. What inspired it: Our Isle of Man AI Community of Practice runs monthly meetups, and December's challenge was to build something festive with AI. That same day, I got a renewal notice for a domain I'd registered 2 years ago and forgotten about: SantaCalls.ai. Well then – let's see how quickly we can build something using AI to build our AI! The build: 3 days. Zero hand-written code. Every line was generated through conversation with Claude Code (Anthropic's AI coding assistant). My job was architecture, direction, and knowing what to ask for. ~15,000 lines of TypeScript, HTML, CSS – all vibe-coded. The stack: Retell AI for real-time voice, GPT-4o for Santa's brain, ElevenLabs for a warm British Santa voice, Cloudflare for hosting, Deepgram for transcript processing. Child safety was non-negotiable: Comprehensive content guardrails, PII redaction, and carefully trained responses for sensitive topics – deceased relatives, divorce, illness. We didn't want any child hurt by a careless AI response. The moment that surprised me most: In QA, we saw a mother-daughter pair call three times in one night. - First call: adorable 4-year-old chatting sweetly with Santa. - Second call: "This is [child]'s mom – she won't take her bath. Can you tell her?" Santa asked for the child, gently talked her through being a good helper and listening to mum. - Third call: "Santa, now she won't go to bed." Santa talked about rest and finished with: "The sooner you go to sleep, the sooner Christmas will be here." None of that was programmed. The AI figured it out from our safety guardrails and its general knowledge. That's when I knew we'd built something special. Local business support: We're Isle of Man-based, so we built country-level routing – when parents click gift suggestions from their child's wishlist, Isle of Man visitors get local Google searches supporting on-Island businesses. Other countries route to appropriate local options or affiliate programs. 100% free. No catch. Just a Christmas gift to families. 🎄 Happy to answer questions about vibe-coding, child safety in AI, or the weirdest things kids have asked Santa for.
