Database of machines, tools, skills, etc

One of the things I thought would be useful is a searchable database of HTB machines classified by OS, Services, Tools, Skills, etc. This would simplify (and even make possible) finding a particular write up or video on a particular tool, technology etc. Does anyone know if this exists already and if not, would it be useful (or am I missing something)?

Of course, this would take effort to classify machines correctly although it might be able to search write-ups or transcripts of videos - although there may be copyright restrictions?

look at the youtube channel of ippsec. He has sorted his machines. You can also google HTB and machines and you’ll find some clustering.
