I made 104 demo videos in 40 minutes, and I didn't record a single one. Claude did. 🤯 http://superdevpro.com is a Chrome extension with 52 developer tools 🛠️, and every tool needs a "how to use" demo, plus a vertical version for TikTok and Reels (52 + 52 = 104). Doing that by hand means 2-3 days of screen recording, endless retakes, my tired voice at 2am 😴, and so-so quality at the end. I didn't want to do any of that. So I gave the whole job to Claude Opus 5.5 🤖. It opened a real Chrome browser on my Mac, installed my extension locally, and used all 52 tools like a real person, with smooth cursor movement, clicks and typing 🖱️ It logged every step with exact timestamps, wrote a script for each demo, voiced it, and put the final videos together 🎬. I just watched ☕ The stack 👇 🎭 Playwright: drives the browser and records the demos 🧱 HTML: draws every frame (captions, overlays, a talking mascot) 🎞️ ffmpeg: joins video and audio 🗣️ Kokoro: free text-to-speech that runs locally, no API key No video editor, no paid voice service, no recording software 🙅‍♂️ The part I love most ❤️ Kokoro gives the timing of every spoken word, so the mascot's mouth lip-syncs to the voiceover automatically. Even the background music is generated in code 🎵 so there's nothing to license. Here's one of the demos 👇
