Software developer, founder, and domain investor shipping Node.js and FFmpeg products on premium domains like karaoke.io and vid.tv.
View ProjectsI'm Jason Greenwald, a developer focused on generative AI music and video. I design and ship the full stack behind my products: Node.js backends, FFmpeg rendering pipelines, lyric-and-syllable-aware karaoke rendering, payments, and the SEO that gets them found. After years of jason.com quietly redirecting elsewhere, this site now serves as a home for my work.
Everything below is a live product I built and operate.
AI music video generator turning songs or prompts into finished MP4s with consistent characters, lyric-aware scenes, and karaoke rendering.
AI music creator delivering synced karaoke experiences plus LRC, SRT, and subtitle file generation.
AI storyboard generator that turns one prompt into a full set of AI-generated scene frames for quick visualization.
Prompt-first AI video generation that builds and delivers finished results to your dashboard.
Beyond the developed sites, I hold a portfolio of premium domain names including donations.com, a category-defining one-word .com. Some run products, some are held as assets, and serious inquiries are always welcome.
