I know I'm not the only one.

I have several armory wallets and for some obscure reason had different passwords for each. At this point there are two wallets whose passwords I cannot remember. They are all strings of the same words and symbols slightly varied. I've spent some hours typing every combination that seems likely but at this point it seems better to try some tool that can crack it knowing the words and symbols in it.

I've looked online and have not seen something that looks useful. Has anyone else had this problem and solved it?

Great idea but you would do well to work on the English. Have a native speaker at least go over your landing page.
e.g. "to understand what is bitcoin" should be "to understand what bitcoin is"
"Find out in this catalog up to 300 related websites" sounds poor etc

It's  not so much about trust, rather about managing risk.
