Free negative keyword tool?

Is there any free negative keyword tool online that lets you remove certain keywords from a list of keywords? I've searched, but couldn't find one.

The reason why I'm asking is because using Ubersuggest I can only add up to 5 negative keywords. When I press enter to try to add more keywords it won't go onto the next line. I'm not sure if this is a bug or the way it has been designed.

You are looking for free one or paid one?

I'm looking for a free one.

Are other people having the same issue with Ubersuggest where you can only add 5 negative keywords? Is there is fix for it?

I tried Ubersuggest using Firefox and Chrome, but the same issue happens in both browsers.
