Mastering AI — From Zero to Building Automations and Agents
You once dropped a question into the chat, got a generic wall of text back, and decided "AI isn't for me." It wasn't you — it was the vague prompt. Here you learn to ask properly: you paste a tested prompt, watch it happen on screen, and finish every lesson with a ready result in hand. No coding at all.
“Paste, test, decide. The AI drafts; the decision is yours.”

My whole team on board with AI
using it consciously and efficiently
“I barely used AI and didn't understand much of it. After the course, I woke up to using AI in my daily life. I set up customer-service routines on my WhatsApp, synced my calendar and automated my email, with AI reading and drafting replies. But the main thing: I got my whole team using AI consciously and efficiently across my organizations, and that is a big step forward. I'd recommend it to business owners, independent professionals, organization leaders and almost anyone who, sooner or later, will end up needing this knowledge, like I did.”
Weslley MatosPastor and business owner (Maringá, Brazil) · Founding cohort3 hours → 30 minutes
to produce one piece of material
“I used to use AI casually, as an amateur really, as if it were a web browser. After the course I understood that AI is a powerful tool I can use intentionally, with clear criteria. It doesn't produce the work for me. A job that would take me three hours on average, with the right prompts we learned in the course, I can now do in 30 minutes.”
Denis VicentinPastor in Maringá, Brazil · Founding cohortEmployees more confident using AI
and faster answers across the company
“I knew very little about AI; I only used ChatGPT. Today I use AI several times a day for company contracts, spreadsheets and lots of comparisons. I see a big improvement in my employees too: they became more confident using AI, and that brought peace of mind and faster answers to my logistics company.”

Your instructor
Ricardo Segura
Founder of OPEX Consultoria
28 years in energy and management. Former director at Schneider Electric, Board Director training from IBGC and an MBA in Strategic Management from FGV. The résumé is nice, but that's not why he teaches this course: it's because he runs two companies that operate with AI every day and teaches only what he uses.

2 days → 2 hours
to put together a report, worst case
“Before the course, I used AI for everyday things, to answer questions, but I didn't use it much. Today I use it a lot for cost analysis, route optimization, price tables and presentations. It depends on the job, but a report that used to take me 2 days, I now do in 2 hours, worst case. I recommend it to anyone who wants to make their day easier and have more detailed, complete reports.”
2 to 3 hours a dayof time saved
“Before, I only used AI for random lookups, searching for answers. Since the course I've set up a daily news digest sent at 3 different times of day, 1 sales agent, 1 sales system and 1 study system that gets fed every week. I'd recommend it to anyone who wants to use AI with precision.”
Tanner MaziniPastor in Maringá, Brazil · Founding cohort“I don't use AI every day, but I sometimes use it to answer emails or draft texts. Taking the course, I realized that with the right prompts the tool becomes more effective and gets the task done faster and more accurately. I recommend the course to every kind of audience, especially people who need speed on tasks that take time to analyze or conceive and want help with their reasoning, saving time for other activities.”
