It's a text editor. It all began with the ed editor, which is very simple and does one thing, it edits files. Then someone extended it into the ex editor. Then someone added a new feature: being able to visually see the file you're editing, which became vi, the visual editor. Then someone improved that, into vim. What began as an editor where you needed to be fluent in regular expressions but otherwise was simple, is now a very complex editor, moving the functionality of the old UNIX tools into the editor itself.

Thank you for explaining!

It's also available on nearly every unix-like machine since the 70s. So, super useful to know how to use. I personally also like (neo)vim as an IDE and its optional regex functionality because that allows once to efficiently edit massive files with minimal effort.
