Ask HN: Need help finding the best tool for text mining

After getting frustrated with online search, and seeing tools that require users to "upload" the data - I thought I'd ask HN. What is the best tool to do text mining? The definition of 'best tool' could be a tool that requires minimum coding (or only in python) - and being able to visualize output. I want to do analysis like - more recurring words/phrases and concept extraction - but don't want to upload my data. Big thanks for your help!
