Gavel is a voice-powered auction marketplace that turns flat online listings into live, cinematic experiences. An ElevenLabs Conversational AI agent acts as a real-time auctioneer — narrating items, reacting to bids, building urgency, and pushing prices higher through emotional engagement over WebSocket. Each listing gets a generated story narrated with custom TTS voices, background music, and sound effects, making every item feel premium. Sellers pay through Stripe to list their items on tiered plans, and winners complete their purchase via Stripe Checkout when the hammer drops. The AI voice layer directly drives higher bids and justifies listing fees — voice as a monetization engine, not a gimmick. ElevenLabs: Conversational AI (live auctioneer), Text-to-Speech (item narrations), Voice Design (unique voices per auction), Music & SFX generation. Stripe: Tiered seller checkout, winner post-auction payment, webhook confirmation.
