Lost my 12 words, but have quick access link, can I recover 12 words from there?

There are tools for the 12 word pass phrase, but it (the 12 word pass phrase mechanism) is very secure.
You’d have to remember a big majority of the words for the tool to have even a remote chance of brute-guessing the remaining few that you don’t remember, but for what it’s worth here it is:

This tool you could run on many computers in parallel and there is no need to spread the load by words, that search is simply probabilistic - you’d use the same parameters on all systems.

I don’t know of a tool that can help with the Quick Access URL. It seems that one is simpler to crack (if you have the URL), but I haven’t heard of a tool that could automate it. Somebody who understands JavaScript could look at Counterwallet source code and see what needs to be attacked and how to detect when the result is success, but I haven’t heard of anyone trying.
