What tools do you use to create product demo videos?

I have been trying to create product onboarding videos that would help users know about all the features I am building in Noogin

I have tried recording myself on Loom but I recently found out, It's a bit hard for me to speak properly on camera 😂😅 (would love to know some suggestions around this as well.)

I have seen tools like descript which provide AI text-to-speech, but I am not sure if people would like to watch them. The voice is still a bit robotic.

Open for suggestions.
