Tool to check for Win 11 compatibility

Hello there, Quick question and I am still looking into this and I was wondering if there is a quick and easy way to lookup if a PC is windows 11 compatible. It would help to check a bunch of random PCs that I encounter day to day and some customers ask me something like "Can my computer still run this Windows 11? It seems fancy." The easier the better but if there is nothing please let me know about some efficient way to check.
