Lab·3 tools used this week
The studio testing ground.
Tools, demos, prototypes.
The Studjoow Lab brings together the tools I build for clients and make freely accessible: an instant SEO and GEO audit with Skovr, an AI palette generator, a Next.js SEO agent, design studies, and typography critiques.
Everything can be used directly on the page, with no installation, no account, and no obligation. It's my way of proving before pitching.

FAQ
Your questions about the Lab.
The six most common questions: what the Lab is, who creates it, and what you need to use it.
What exactly is the Studjoow Lab?
The Lab brings together the tools, demos, and prototypes I test in the studio: Skovr (an instant SEO and GEO audit), an automated moodboard pipeline, a Next.js SEO agent, and design studies. Everything can be explored directly on the page, with no signup required.
Why make all of this freely accessible?
Because it’s the best proof of expertise. Instead of making promises, I show the work. If you understand how my tools work, you know exactly who you’re working with when we start a project together.
Who creates the Lab content?
John Houzi, founder of Studjoow. 18 years of experience in design and development. Every demo is designed, coded, and published by me.
How long does it take to try a tool?
The Skovr audit takes 30 seconds for a standard site. The other tools are shown as animated previews on the page, so you can see the result without installing anything.
Are the Lab tools really free?
Yes. The public demos and the Skovr audit are free to use, with no account and no payment required. Skovr’s scoring logic is proprietary, but the simpler agents and pipelines are openly documented.
What happens after an audit?
You receive an actionable report. If you want me to fix things with you, we exchange an email and scope out a quote. Otherwise, you leave with your report, with no obligation.
Another question?

Why
Expertise is not proved
by slogans.
The Lab is what I test, break, and publish. Everything can be explored. If you hand me a project, you'll know exactly who you're working with.
