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 Sk:vr, an AI palette generator, a Next.js SEO agent, sourced law for AI assistants, 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.

Rayon X de marque.

A live brand diagnosis. Paste your website URL: an AI art director visits it in real time, reads your palette, type and tone, scores your brand maturity, then sketches an alternative art direction before your eyes, down to a mark drawn stroke by stroke in generative SVG.

Claude Opus 4.8.

An analysis of Anthropic's model released on May 28, 2026. Why Opus 4.8 is the best LLM for agentic coding in 2026: 4× fewer defects let through, 1M-token context by default, dynamic workflows with hundreds of parallel sub-agents. The LLM I run in production every day.

FAQ

Your questions about the Lab.

The seven 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: Sk:vr (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.

  • What legal tools does the Lab offer?

    Two MCP servers built by Studjoow: Droit by Studjoow (droit.studjoow.com) connects Claude or ChatGPT to official French and EU law, with a free trial of 20 requests a day and a subscription from €4.99 a month; Mishpat (mishpat.studjoow.com) does the same for Israeli law, free of charge. Every cited reference is checked against the official texts. This is legal information, not legal advice.

  • 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. Design and development since 2009. Every demo is designed, coded, and published by me.

  • How long does it take to try a tool?

    The Sk:vr audit takes under 15 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 Sk:vr audit are free to use, with no account and no payment required. Sk:vr'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?

If your question isn't on the list, write to me. I reply within 24 business hours.

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.
