The Builder Digest.
I research AI tools every day to find what actually saves a business time. Once a week I send you the best, with links and what each one is good for.
What you get.
The week's best research
The posts that earned the most attention this week, so you read the useful ones first.
Tools and repos, with links
What each tool is good for, my notes, and the repo, video or thread behind it.
3 prompts to build with
Practical prompts based on the week's tools, ready to paste into your AI.
New free skills
Claude Code and Codex skills from my real workflows, free to download.
From the studio
One system I built or I am building, so you can see how this works in practice.
See a sample issue.
The top posts of the week, five tools with their repos and videos, three prompts, a free skill and one system from the studio. This is the format every issue follows.
Written for people who build.
Business owners
You want the AI tools that give your team hours back, explained in plain language, without testing fifty of them yourself.
Builders
You want the repos, models and workflows worth trying this week, with the links, before the hype cycle catches up.
I am João Queirós, an AI systems builder in Porto. See what I build.
