How I use AI

AI has become a fundamental tool. On this live page (inspired by Derek Sivers and Damola Morenikeji), I’m sharing how I use AI in my day-to-day work, and which parts of my output can be considered AI-created, AI-enhanced, or entirely non-AI generated.

Coding

I use Copilot extensively (with a variety of models: Gemini, Claude, etc). I mostly use AI as a rubber duck, a companion to bounce off ideas, explore alternatives, discuss pros and cons, etc. I rarely ask AI to implement features or drive code changes, except for small dependency updates or writing companion documentation. This alone is already making me feel much more productive without doing any vibe coding (yet).

Writing

Almost all my English writing is reviewed by AI.

I’ve designed a custom GPT in ChatGPT with specific instructions to ensure it doesn’t change my tone, writing style, or introduce any new arguments, but instead corrects grammar mistakes and suggests alternative phrasing when something doesn’t sound natural to an English-speaking audience.

Since English isn’t my native language, this extra review layer gives me more confidence before publishing (whereas I never use AI when writing in Spanish). I could probably manage without it at this point, but I’d have to spend a lot more time correcting errors, re-reading, etc. All content is still human-generated, as I don’t use AI to produce original text. My goal is not to generate content but to share my thoughts when I feel like it.

Day-to-day

AI has largely replaced my use of traditional search engines, since I use AI all the time to research different topics. The way it works for me is: I use AI in the early stages to get a good overview of a topic, then fall back to my previous habits (search engines, Wikipedia, books, etc.) to explore the topic in more depth.

One interesting use case in my personal life is traveling. I’ve recently started using AI while visiting new cities to learn more about specific aspects. For example, I had to take a business trip to Boston and was walking around the Harvard campus asking AI questions about the history of Harvard, etc. I did the same while traveling to Tokyo. I still do my own research and planning when traveling, but AI has been especially helpful in those moments when new questions come up on the spot.
