WordSmith Tools has at least two functions with Wordlist that you can use:
A) Using Wordlist to generate two (or more) word lists, then under WordList
1. Open a wordlist.
2. In the menu, choose File | Compare 2 wordlists.
3. Choose a wordlist to compare with.
B) WordList -> Detailed Consistency analysis
Wordlis -> New...() you will be offered a tab showing detailed consistency. Choose at least two word-lists and press compute Detailed Consistency now.
(You can also use the Keyword function, though this may be slightly different from what you wanted.)
