What I Build

Yellow House Digital builds custom AI tools for marketing and creative agencies - and websites with the same thinking built in.

In practice: custom AI tools, MCP servers and the APIs underneath them - usually where the SaaS teams find me - websites and applications, automations, research instruments. I publish how I work, so you can check the methods before you pay.

The work

Custom AI tools for agencies

Lead screening, research instruments, automations, internal tools that fit how your team already works. This is where I spend most of my time.

MCP servers & APIs

The plug that lets AI assistants use your product's data safely - and the APIs underneath it. I run production MCP servers every day; ask me to show you one working.

Websites & applications with AI built in

Sites that machines can read and humans enjoy - and web applications with AI where it actually helps. Much of my work starts here.

A different kind of help

Not everything needs building.

AI-readability audit

Sometimes you need to know what the machines see. Can ChatGPT, Claude, and Perplexity actually read your website? Seven checks, most fixes done in an afternoon. You'd be surprised how many good-looking sites fail.

Advisory

Sometimes the hard part is deciding, not building: what to build, what to ignore, what to test first, and what good enough looks like right now. I help you make those calls - no build required.

Talk to me

I measure what the AIs actually say

Once a month, an instrument I built asks ChatGPT, Claude and Perplexity the questions agency buyers actually ask - every question twice, every answer stored verbatim. It is why the AI-visibility work here - the audit, the checklist, the guides - comes from measurement, not guesswork. The findings publish open in Writing - the first run is here - no gate, as always. If you want to know what the assistants say about your niche before your competitors ask - that is a conversation.

Indie builds

Between client work I build small tools constantly - a measurement instrument, a content calendar that posts to X and LinkedIn, a tool that turns podcasts into searchable notes. Each one solves a problem I kept hitting or taught me a technique by building something real - and all of them run in production, for me. If one sounds relevant to your agency, ask - I will show it working.

A guide I wrote

Before you hire anyone - including me

How to choose an AI development partner: what to look for, what to demand in the deal, and the red flags that predict a wasted budget. I wrote it because I've seen both sides.

Proof, not promises

Everything here is already built and running in production. See the work for yourself.
