Stage is an AI-powered product tour generator. Paste any URL and our multi-agent system autonomously browses the app, captures screenshots, writes a narrated script, and generates a polished shareable tour — all in under two minutes. The pipeline runs four AI agents: Scout (Gemini CLI running headlessly inside Vercel Sandbox with Puppeteer — autonomously navigates, screenshots, and reasons about which pages to explore), Director (Gemini 3.1 Pro vision analyzes screenshots and writes a demo script), Narrator (ElevenLabs generates voiceover audio), and Assembler (creates a shareable auto-playing tour page with transitions and synced audio). The Scout is the standout — it's a full Gemini CLI agent running inside an ephemeral Vercel Sandbox microVM, writing and executing Puppeteer scripts, reading screenshots, and deciding where to navigate next, all streamed to the frontend in real-time via SSE. The UI itself was designed using Google Stitch for rapid high-fidelity interface design, then built with Next.js 15 and Tailwind.
