Welcome to my YouTube channel!
Here, you'll find step-by-step tutorials on building real-world solutions with AI. From AI agents and automation workflows to vibe coding and agentic coding, I cover it all - using both code and no-code tools like n8n, Claude Code, Codex, Cursor, and more.
Whether you're a vibe coder building your first app with AI, or a developer integrating agents into your workflow, there's something here for you. I focus on practical, hands-on tutorials that you can follow along with and implement right away.
New videos every week - thanks for stopping by, and I hope you enjoy the content!
Let’s work together!

If Blender always felt too hard to learn, an AI agent can now do the 3D work for you.

Fable 5.1 or GPT-6 Astra? I made them work together on one game instead. Which model are you using?

My AI assistant now has her own computer. Would you trust one to run tasks for you 24/7?

OpenAI just released Dots, their answer to OpenClaw and Hermes Agent.
If you're already on ChatGPT Pro, you get an always-on agent with its own computer and browser that learns from you. No self-hosting, no VPS.
I set mine up in today's video: https://youtu.be/niv2BEcOkR8
So, what's your plan?

Sonnet 5.5 is supposed to cost about half as much as Opus 5.5.
I gave both of them (plus Fable 5.1) the exact same prompt in Claude Code: build a polished 3D mini golf game.
How much cheaper do you think Sonnet came out?
The answer is in my latest video: https://youtu.be/NzyP4VjkrvM

Everyone's calling Jev from TypeSafe AI a Claude killer. It isn't. It can't even write a full sentence.
It's a System 1 model built for instant decisions (pick an option, give a score, answer yes or no), and that's exactly where it beats Claude on speed and cost. In my new video, I use it to label every new GitHub issue and route it to the right coding agent: https://youtu.be/iyIAdmeKeMM
When you first heard about Jev, what did you think it was?

I just built a software factory, and it's the easiest way I've found to do it.
It runs in GitHub with minimal setup. An agent swarm works on your projects, and every agent runs in its own sandbox.
I also made an agent skill you can use to set up your own factory today.

What happens when Claude and GPT-6 work on the same team? 👀
This is what excites me about combining models from different providers: you can use each model’s strengths within the same project.
Think GPT-6 Astra for computer use and understanding 3D environments, paired with Claude Fable 5.1 for advanced coding and backend logic.
I tried this combination in Abacus AI Supercomputer with one prompt: build an online multiplayer survival game.
About 20 minutes later, it had built, tested and hosted the game, including the server and database.
The wildest part? I joined the game and found the AI’s character already walking around collecting resources. 😂

I’m genuinely excited to share that I’ll be speaking at the AI Practitioners Summit, October 19–23.
What I love about this event is that it isn’t about sitting around talking about what AI might do someday.
It’s about what you can do with it right now.
The summit is bringing together 60+ people who are actually building, implementing, experimenting, automating, creating and getting results with AI.
And the goal is simple:
You should walk away with ideas you can use.
- Ways to save time.
- Ways to work smarter.
- Ways to create more.
- Ways to improve how you run and grow your business.
- And practical examples you can take back and start implementing.
I’m incredibly proud to be one of the speakers.
If you’re trying to figure out how AI can genuinely make a difference in your business, rather than just adding another shiny tool to your stack, this is one to put in the calendar.
🎟️ Free registration: event.aipractitionerhq.com/?sc=8nwVzD4L&ac=rlyjSTF…
I’ll see you there.

GPT-6 Astra and the Blender MCP is wild.
I asked GPT to research how guns worked, and it animated the pistol (without downloading existing assets by the way!)
