I am a maths teacher and I want to make maths explainer videos particularly like this guy is doing. In fact, in my research, I came to know that manim is the latest tool for creating maths animations but it is hard and time-consuming (at least for me) because it requires python and long codes. But I am sure this guy is not using manim. If you know how one can make such videos please let me know.
Possibly, he is using blender but I am not sure as I am new on blender.
Thanks.
