I build things.
And I test everything.
Hey, I'm Fabian. By day, I'm the CPO and Chief AI Officer at a healthcare tech company in Switzerland. By night, I'm the nerd tearing apart the latest AI models to see what makes them tick.
This entire website started on a random Saturday afternoon. I remembered I had this domain sitting around and wanted to challenge myself: how quickly could I build a fully usable, beautifully designed website from scratch using modern "vibe coding" tools?
I have zero natural talent for design—I usually can't even pick matching colors! But by leveraging Claude Code with Opus 4.6 and Gemini 3.1 inside Antigravity, I was able to architect, design, and deploy the Good AI Guide in just 48 hours. Now, it serves as my personal sandbox, my tech-stack journal, and my way of sharing what *actually works* when the marketing hype fades away.
"AI isn't about the model parameters. It's about what you can actually build with it before your coffee gets cold."
Methodology
How I Break Things (So You Don't Have To)
I don't just run a "hello world" prompt. I integrate these tools into my actual daily workflow.
Real-World Production Tests
Demo magic is meaningless. I test if a tool can handle complex, edge-case production data or if a non-technical professional can actually figure out the UI without crying. If it fails the real-world test, it doesn't make the list.
Output Quality
I compare models head-to-head on identical, complex prompts. Zero cherry-picking allowed. You get the raw truth about hallucinations and fidelity.
Value for Money
If an open-source model gives you 90% of the capability for free, I'm going to tell you to use the free one.
The Speed & Learning Curve
Time is literally money. I measure the "time-to-first-value." If a tool has terrible documentation or requires a PhD to install, you'll know about it here first. Let's stick to tools that actually multiply your productivity out of the box.
Ratings
Rating System
I use a simple 5-star rating scale. Here's what each rating means:
Exceptional
Best-in-class. I use this regularly and recommend it without hesitation.
Excellent
Great tool with minor limitations. Strong recommendation for the right use case.
Good
Solid option with notable trade-offs. Worth considering depending on your specific needs.
Below Average
Has significant issues. I'd usually recommend an alternative unless you have a very specific reason.
Not Recommended
I don't include these on the site. If something doesn't deserve at least a 2, it doesn't make the cut.
Affiliate Disclosure
Transparency matters to me. Some links on this site are affiliate links, which means I may earn a small commission if you sign up through my link — at no extra cost to you.
Here's what I want you to know:
- Affiliate status never influences my ratings. I recommend tools based on quality, not commissions. Many tools I recommend highest don't have affiliate programs at all.
- I clearly mark affiliate links. You'll always know when a link is an affiliate link.
- I only recommend tools I've actually used. No tool gets on this site just because it has a good affiliate program.
Affiliate revenue helps me keep this guide free and updated. If you find value here and want to support the work, using my links is a great way to do that.
Speaking & Teaching
Between my startup and other projects, my schedule is admittedly quite packed. However, I am always open to exploring speaking engagements, guest lectures, or workshops! There are few things I enjoy more than sharing knowledge, cutting through the AI noise, and exchanging ideas with like-minded people. If you have an event or team in mind, don't hesitate to reach out.

Get in Touch
Have a tool you think I should review? Found an error? Want to collaborate? I'd love to hear from you.
The best way to reach me is on LinkedIn. I read every message.
