I used Trelent, an extension for VS code that didn't require any registration, but their server has been unresponsive for a while. Any alternative you would recommend?
My code is in Python, mostly.

Edit: I wasn't clear on my intention. I was looking for a tool that would lay out a generic description so I would start from something and fine tune the explanation.
I am incredibly bad at documenting, the process is tedious and frustrating. At the end of the day, my explanations are mostly gibberish anyway.
From your general consensus, I should bite the bullet and do it by myself.
I really appreciate your feedback, point taken. Time to psych myself up with some death metal and get it over with.
