Jason Greenwald

I build systems that turn domain names into working software — websites, applications, and the AI hosts that live on them. I've owned jason.com for more than two decades.

Yes, this is really jason.com — my personal site, project portfolio, and domain portfolio.

About

I'm a developer and domain investor. For years I built AI music and video products; lately I've been building the layer underneath them — a pipeline where you describe an application and agents plan it, design it, write it, review each other's work, drive the result in a real browser to prove it works, then host it and cast a character to greet whoever shows up.

That pipeline is the thing I'm most interested in. It means a domain name doesn't have to sit parked earning pennies: it can become a real site with a real tool on it, in minutes, for about the cost of a coffee.

I ship the whole stack myself — Node.js services, rendering pipelines, payments, DNS and hosting, and the SEO that gets any of it found. Everything below is live and operating, not a prototype.

How the factory works

Every application goes through the same six stages before anyone sees it. Different models do different jobs, and the result has to survive a real browser.

01Concept

The request becomes a title, a storyboard of acts, and what each act must prove.

02Design sheet

A six-panel product sheet is generated and read back with vision, so the coder builds from a design.

03Code

One self-contained file under a strict content policy — nothing external, nothing phoning home.

04Review

A second model audits the first and may return a correction, adopted only if it also compiles.

05Proof

A headless browser clicks the buttons act by act and reports which promises the app kept.

06A host moves in

A character is invented, drawn, and filmed with a matched voice — then greets every visitor.

Projects

DomainMagic.comlive

Turns a domain name into a real website in minutes — copy, artwork, brand pack, and an AI editor that changes the site in plain English. Sites can now also grow a working application and an AI host, and every build is audited by an automated site doctor.

AI websitesBrand assetsStripeDomainer tools

demos.iolive

Describe an application and agents build it: planned in acts, designed before coded, reviewed by a second model, driven in a real browser to prove it works, hosted immediately, and given its own character with a face and a voice who can edit the app by chat.

Vid.tvlive

AI video agents for websites. An on-brand host answers visitors in video instead of text, seeded from the site's own content — plus a site doctor that audits a page the way a visitor actually sees it and reports findings with evidence.

BrainForYourDomain.comnew

Field notes and free tools for domain investors, arguing a simple case: a parked domain earns pennies, but the same name with a working tool and an AI host on it becomes property worth visiting — and worth more when it sells.

Domains

I've been buying and holding names since the nineties, and several of my products live on category-defining ones — karaoke.io, vid.tv, donations.com. The rest of the portfolio, currently 112 names, is listed on the domains page.

Most of them are parked, which is exactly the problem I've been building my way out of.
