Ghost Negotiator is a voice-first web app that helps you handle painful real-world phone moments (like canceling a gym membership) using ElevenLabs Conversational AI—so the interaction feels natural, fast, and “human enough” for a real call scenario. Built for #ElevenHacks with Cursor, the experience is designed for a polished demo: preset scenarios, a live-call UI, transcript bubbles, and a demo mode (?demo=1) for a repeatable vertical video flow. How I used the tech ElevenLabs: conversational agent session in the browser (@elevenlabs/client), voice interaction, and dashboard-driven agent behavior for the “real call” path. Cursor: end-to-end product iteration—UI polish, PWA installability for mobile filming, and demo sequencing for a tight on-camera story. What makes it special It’s not just “chat with an AI”—it’s framed like a real phone negotiation with cinematic UI states (calling → on-call), a clean transcript experience, and a demo path optimized for 9:16 filming and home-screen install.

Voiceprint is a psychological horror game where the monster hunts you using your own voice cloned in real-time by ElevenLabs. WHAT IT DOES You explore an abandoned radio station that mysteriously kept broadcasting after closing eleven years ago. Halfway through, the game asks you to speak into your microphone for fifteen seconds. ElevenLabs clones your voice instantly. Within moments, the monster starts whispering at you from the dark in your own voice. "I'm right behind you." "Don't turn around." Players hear themselves say things they never said. HOW WE USED ELEVENLABS (5 APIs) - Instant Voice Cloning clones the player's voice live, mid-game, then uses the cloned voice ID to generate monster whispers - Text-to-Speech (Cedric voice, Eleven v3) cinematic narrator throughout - Sound Effects API ambient drone, footsteps, monster sounds, distant whispers, transition impacts - Music API original 60-second horror score for the trailer - All routed through Vercel serverless functions to keep API keys server-side HOW WE USED ZED Built end-to-end in Zed using its AI agent panel for rapid iteration on the Three.js scene, voice-cloning audio routing, monster AI, and shader pipeline. Zed and ElevenLabs are both built into the world as in-game sponsor posters pristine on one wall, defaced with red spray paint on another. Worldbuilding, not branding. WHAT MAKES IT SPECIAL This game cannot exist without ElevenLabs. Voice cloning isn't a feature added on top it's the entire mechanic. Last year's Supernormal made you talk to ghosts. This year's Voiceprint makes the ghost talk back, in your voice. Built in 4 days. Runs in any browser. Microphone required. Live demo: voiceprint-alpha.vercel.app

BriefBot is a real-time AI voice news anchor. Ask it anything about current events and it delivers a structured, broadcast-quality briefing spoken back to you in seconds in your language. How it works: ElevenLabs Conversational Agent handles voice input and output using George's broadcast anchor voice. When you ask a question, the agent calls a custom webhook that fires the Firecrawl Search API to retrieve live structured web content in real time. The agent synthesizes the results and delivers a spoken briefing. Key features: - Live web search via Firecrawl — zero hallucination, always current - 4 languages: English, French, Spanish, German — auto-detected via Scribe v2.1 - Morning briefing — 5 parallel Firecrawl searches at once - Source transparency — every briefing shows clickable sources - Live news ticker — real headlines fetched on page load - Text input mode — no microphone needed Built with: ElevenLabs Conversational Agents + Scribe v2.1 + V3 Voice + Firecrawl Search API + Node.js + Express. Deployed on Railway.
