Hey Hippy,
In the absense of anyone breaking their leg to try to build you a tool, would you be willing to use Excel? It's really pretty quick and easy.
Here goes...
Put your keyword phrases into a plain text file, like notepad. Use the edit>replace function to replace spaces with commas. In the "Find What" box, type a space and in the "Replace With" box type a comma.
Now, each line should look like:
word1,word2,word3
There shouldn't be any spaces between any of the words, only commas. Also make sure you don't have any rogue leading or trailing spaces. You can do the replace function again, this time put a space in the "Find What" box and don't touch the "Replace With" box. That'll eliminate all the spaces for you.
Save the file with a new name so you don't lose your original.
Open Excel and start a new workbook. On the menu bar, select "Data" and in the drop down, choose "Get External Data>Import Text File." Double click on the file you just added commas to and a window will open that should already have the "delimited" box ticked and will show you a preview of the file. Click "Next."
In step 2, select "comma" and deselect anything else that may have been selected by default. Click "Next."
In step 3 of the wizard, leave the tick for "General" under "Custom Data Format" and once again, you'll see a preview. It should show all the words seperated into their own columns. Click "Finish." Another little window will pop asking you where you want to save the data. Click OK and it'll populate the fields.
Now, place your cursor on the letter at the top of the first column, (A) right click and copy, then paste into a clean notepad file. Save it and repeat for each column.
Open each file and clean out the duplicates then resave them.
Now you can copy and paste each set of single words into whatever keyword mixer you want to use and it'll mix and mash them up into all sorts of combinations.
It sounds more complicated than it is but, after you've done it once, you'll sail through it.
Granted, it isn't as cool as anything fully automated but you get what you pay for and this was free. HAH!
Hope it helps.
