KW difficulty tool – that requires no manual input?

Hi,
I've read on a lot of place thats KWFinder is the best for assessing the difficulty of KWs. However, the main issue i've had is that you have to click on the difficulty score one by one… this is a huge task for long lists.

Is there any tool that you use that doesn't require manual clicking of every KW?

Would love to hear your input.
