Mateusz Chrobok: from a YouTube channel to his own platform

A cybersecurity expert who shares what he knows

Mateusz Chrobok has worked in cybersecurity for more than 15 years. He worked at Samsung, investigated data leaks at large companies and nonprofits, was a Security Officer, and built his own products — including ScanMe, devices that detect eavesdropping. Today he supports startups in security and AI.

In October 2021 he started a YouTube channel. The idea was simple: take topics that scientists and security specialists write about, and explain them so anyone can understand. More than 160,000 people subscribe today. Mateusz also runs a podcast and a newsletter read by several thousand people, appears in many media outlets, and regularly with Tomek Rożek on Kanał Zero. He also teaches programmers in AI_devs, which he co-creates.

From a channel to his own platform

YouTube gave Mateusz reach and the trust of viewers. But a video of ten or fifteen minutes cannot cover everything. That is why in 2024 he launched Uczmnie.pl — a platform of courses and ebooks on cybersecurity, AI, and using the internet with care, where you can go deeper.

The rule stayed the same as on YouTube: teach what you know from practice, and say it in plain language.

“Uczmnie answers the needs people bring me. It is a recipe for the problem that shows up in a given topic.”

Courses on Uczmnie.pl range from short guides, for example “What to do if someone steals your phone,” to ones that take a few evenings. Topics include:

• A child online — a manual for adults on looking after a young person on the internet,
• AI safety — how to use AI tools safely at work,
• How to use Claude Code — from zero, on working with an AI assistant,
• The law and AI — what you may and may not do when you use AI.

Other experts teach some of the courses, including Tomasz Jach, Piotr Stefański, and Michał Nowakowski. The average rating on the site is 5.0.

Every product in one place

Every Uczmnie.pl product is sold through Easytools. Buyers can choose a specific ebook or course, or — when it is available — a subscription that gives them every piece of material and a closed community.

That way each customer can pick the product that matches their level and their budget.

A subscription you do not have to police

The Uczmnie.pl subscription comes in two versions — monthly or yearly. Renewals and payments are fully automated in Easytools, so Mateusz does not have to manage subscriptions. Users can also switch plans themselves — for example from monthly to yearly.

One system

With Easytools, Mateusz does not have to connect several systems, keep them working together, or maintain his own infrastructure. The whole sale is in one place, and he can focus on new courses.

What makes this story stand out

Mateusz has spent years on anti-fraud systems and machine learning, so he knows where the risk hides. He does not scare people. He shows how to protect yourself — in plain language, and with examples from life.

What matters most is how concrete it is. His courses are as short as they can be, and what they teach can be used immediately.

Summary

For years Mateusz has explained technology so anyone can understand it — on YouTube, in the media, and in AI_devs. On Uczmnie.pl he gathered that knowledge in one place. If you need one thing, you buy one course. If you want more, you stay on the subscription and get something new every month.
