I have learned a lot so far. The 4 stars is because of the instructor's accent, it's not really bad, I just feel like I might be missing something. Maybe I can slow it down?

The recording icons at the bottom left of the videos are covering some of the context in the lessons. Hiding that recording bar would be great when making videos.

Its a nice course, it provides a course material one can read for free

so far so good especially how everything is explained and taught in an easy to understand manner

By Alex Bizanidis on 1/19/2026

The course really helped me expand my understanding of the evolving presence of toolkits and use cases, but I got a bit confused by its structure. Overall valuable, thank you.

This course was a good starting point. I have already used AI in daily business operations and needs, but good to review.

By Richard Jones on 10/19/2025

Some parts more relevant for me than others, but overall a high quality. I particularly enjoyed Eugene's demos because they weren't perfect first time and he included all of the problem solving and troubleshooting.

By Charles Bartlett on 8/24/2025

For a course titled "Building Basic AI Agents and Custom GPTs", this covers way too much superfluous material. Some of this would be better presented in an "Introduction to GenAI" course (GPT examples, Ways to use AI to advance your career, etc..).

By Muhammad Zain Tariq on 8/20/2025

This course seems to be More Good than I thought

By Ankit on 7/26/2025
