Here are a few Colab notebooks for daily routines:
A basic video editor developed for my friend who has no experience at all in the subject but wants to use short videos with subtitles in his lectures (lots of instructions!).
My current little helper. At pragueschool.media, we host lots of public educational events, and Chunks helps us build our archive in various formats and two languages.
It's the easiest onboarding to Colab ever, providing the brave experimenter with a free and secure tool to play.
