I have a suggestion for those that don't have a burning hatred of all things AI or Google - try NotebookLM (https://notebooklm.google/) which is FREE for limited usage. It may take you a few tries to learn how to use it effectively *there are videos showing how) but what you can do is give it a list of URL's on any topic. These can be man pages, wiki links, PDF documents, links to specific posts or discussion forums, YouTube videos, or almost anything that can be accessed via a link. You can include up to 50 links for free (up to 10 at a time, I think it is a bug that if you try to add more than 10 at once it just silently fails and then you have to go to a different "notebook" and come back to try again).

Then when you have added all your links, you can ask for a summary of the material, or ask specific questions based just on the links you have added (no more outdated responses). You can even do things like generate graphics or audio "podcasts" or even videos with really bad visuals (IMHO) based on your links collection if you want to. But what I find is when dealing with complex material it often makes connections that I would never have seen. And did I mention it's free for limited usage? You just need a Google account to use it (and yes I realize that's a non-starter for some people, and no I would never ever include anything personal in my links or requests).
