Legal notice and Terms of use

Last updated: October 3, 2026

By using this site you agree to these terms. They are few and simple.

1. What this site is

A free personal journal about learning with artificial intelligence, written by Rodrigo ES Porto. I don’t sell courses or services here.

2. Educational content, not advice

Everything here is my own experience and educational material. It is not technical, legal, accounting, financial or investment advice. When I mention my personal finances, it is biography, not a recommendation. AI tools change fast and can be wrong. Double-check, test in a safe environment and back up before following any step-by-step guide.

3. No warranties

Content is provided “as is”, with no guarantee that it is complete, current or error-free. To the extent permitted by law, I am not liable for losses arising from the use of information on this site.

4. Use of AI

Texts are written with the help of AI tools and reviewed by me before publishing. AI-generated images, if any, will be labeled.

5. Content license: CC BY 4.0

Unless stated otherwise, the texts on this site are licensed under Creative Commons Attribution 4.0 International (CC BY 4.0). You may copy, share, translate and adapt them, including commercially, as long as you:

  • link to the license; and
  • indicate if you made changes.

Not covered by this license: third-party trademarks, names and logos; theme and library code (each under its own license, see below); quoted third-party content; and AI-generated images, which may not be protected by copyright.

6. Trademarks

Google, Gemini, Google Antigravity, Claude, Cloudflare, Grok, xAI, X, Cursor, Hugo, Hermes and other names mentioned belong to their owners. I mention them only to identify the tools I use, for non-commercial purposes. This site is not affiliated with, sponsored or endorsed by any of these companies or projects.

7. External links

Links to other sites are provided for convenience. I don’t control their content or policies.

8. Ads and partnerships

This site has no ads or sponsored content today. If that ever changes, it will be clearly labeled.

9. Privacy
