DemoPilot - Autonomous Demo Video Agent

Every software team needs demo videos, for investors, judges, launches, and onboarding. Today, creating one means recording in OBS or Loom, re-recording every mistake, editing in timeline software, and hiring voiceover artists or settling for robotic TTS. A 3-minute demo can take min 2–4 hours. Who has time? Introducing DemoPilot, a fully autonomous AI agent that generates production-ready demo videos from a URL. The pipeline is end-to-end, with no human touches required. It starts with Capture, where Playwright visits the target URL and captures a screenshot plus page structure, including nav links, buttons, headings, and form fields. Next is Script, where Gemini 3 Flash analyzes the screenshot and elements, then writes a narrated demo script with actions like click, type, scroll, navigate, and hover using real CSS selectors. In Record, Playwright drives headless Chromium at 1920x1080, adding gold click glows, smooth scrolling, and character-by-character typing for a natural feel. Narrate uses edge-tts to generate neural voiceover with 10+ Azure voice options, timed to each segment. Finally, Compose uses ffmpeg to merge recording and narration into a polished H.264 MP4. DemoPilot also supports voice-to-script: users speak their demo intent into a mic, Speechmatics transcribes it, and Gemini turns it into a structured script. AI Quality Assurance uses Gemini Vision to review six final-video frames, score quality, and flag issues. Other features include cookie consent auto-dismissal for 80+ CMP selectors like OneTrust, Ketch, and Cookiebot, deterministic output for CI/CD workflows, and full manual override so users can edit every segment before rendering. DemoPilot reduces demo video production from hours to minutes. It is built for hackathons, SaaS companies, and developer advocates who need professional demos without professional video editors. Both landing page showcase videos, that were generated by DemoPilot, from URL to finished MP4, untouched by human hands.
