What I write about AI and product.

The 5 folders, the 3 tools and the prompts I use to have Claude Code edit my reels in my style: captions, cuts, animated text and sounds, with the draft in CapCut. Plus my style files to download.

From not knowing how to code to securing apps, putting them in the cloud and building with LLMs and agents: seven courses that don't repeat each other, what you learn in each, how long they take and what's actually free.

What your app needs so you know when it breaks, when it goes down, where people come from and what they do inside, ranked in tiers with what each tool gives you for free.

Wikipedia keeps a list of the clues that give away a text written with AI. I used it to make a 4,980-character prompt you paste into ChatGPT's custom instructions.

The 7-line prompt, the Avoid line and the named styles that keep your poster from looking AI-made.

Free, open-source programs that do the same as the subscription you pay every month, from most to least stars on GitHub: which app each one replaces and its link.

If your site has more than ten of these, it shows AI made it. The 100 giveaways and the prompt to get rid of them.

Each AI searches somewhere different. Where each one looks, the sitemap you need and how to submit it to Google, Bing and Brave.

You type and the letter shows up late, you open a menu and it just sits there. It is almost always one of these five things, and none of them makes you rebuild your app.

Brutalism, minimalism, glassmorphism, liquid glass, bento grid and seven more, on the same landing page. Switch styles, tweak each one and copy the prompt that builds it that way.

The 300 skills for Claude Code, Codex and other agents with the most stars on GitHub, from most to least: what each one does and its link.

Gradients, Lucide icons, three cards in a row, em dashes and made-up testimonials. Tick the ones your site has, see your score and take the prompt that avoids all of them.

Brag, prompt-motion and Remotion: what I use to have Claude make 15 to 30 second ads without opening a video editor. With the SICREW video and the prompt to make yours.

Getting the AI to write code is the easy part. The hard part is explaining how your product has to work, how it is built and how to know it works. These are the documents that solve it, with a full example of each one.

Design skills, components with a prompt, screenshots and HTML from other sites, ideas from ChatGPT, Motion and GSAP, and scroll-driven video. What I do so a website does not look templated.

Obsidian remembers what you already know and where you fail, Claude or ChatGPT decide what to focus on and NotebookLM makes you practise. The whole system, with the five prompts.

Before building anything, check that someone wants to pay for it. These are the ten steps I follow to validate an idea without spending any money.

These are the phases you should go through to scale your application properly and not lose users along the way.

If you want to build an application while watching Netflix, this is all you have to do. I walk you step by step through the setup I am using right now.

I started using Claude in October last year. Over time I have stopped doing things I used to do badly. They are simple, and fixing them takes no time at all.

Check all of this before you push your app to production. It is easy. At the end of the article there is a prompt so your agent does it for you.

The nine things a developer has to know so as not to be the door they come in through. Explained without jargon, one diagram each.

It is easier than you think. Anyone can do it. Just read this:

You do not have to build them all. Pick one and start there. These automations will save you a lot of time in the long run.

Twenty-six holes people get into AI-built apps through, from what you fix this afternoon to what you have to understand

DRY, KISS, YAGNI, SOLID, CRUD, ACID, TDD, MVP and CI/CD: what they stand for and what someone is really saying when they drop one in a meeting.

Frontend has moved to the server, stopped repainting everything and finally has proper design tools of its own. Here is what you need to know.

Stop hitting the usage limit. Ten tricks to make your tokens feel unlimited: the same messages at a fraction of the cost, updated to how Claude works today.

Save tokens on every subscription, improve your web design, make your text sound human and have a whole marketing team.

Learn some of the most important things a backend developer is expected to know today.

Cheap, useful AI and algorithms that reward the small player. Put the two together and you have the opportunity of your life.

AI is not intelligent, that is what you have been led to believe. It does not think: it makes mathematical predictions.

The complete setup for building applications for free, with no technical knowledge and full control from your phone.

The opinion of someone who has been developing for more than 10 years and feels this discipline has lost its soul.
