By Amitabh Kamalkant Kapil on 8/8/2025

I liked it. Starting the course from basics and going into detail. Some of the details were too technical for me, but always good to know.

By Adekunle Oluwatomisin on 6/11/2025

It's a good course but I wished it had questions at the end of each video

By Patapee Panbupha on 5/15/2025

The content is acceptable and fairly easy to understand, but the audio levels of each clip are inconsistent, which makes it a bit uncomfortable to listen to.

By Aiman Enriquez on 5/14/2025

Personally, I do like the natural voice from every hands-on presentation instead of the robotic and emotionless voice over. I am here for Code making prompts and not video generation. The course contents are nice and detailed I dislike the presentation slides. I looks like AI-generated due to being confusing design decisions. I also dislike the AI-generated pictures on it. Flickering light sensitivity warning at Section 5: 19. Content Generation Section 5: 21. Business and marketing automation
