A couple of days ago, a fella posted on this sub asking for a free TF-IDF tool. I know Ryte has one, but I believe you have to create an account, and I don't know if they limit it beyond that. I made a quick tool that probably needs some improvement, but I'd like the feedback.

Here's the synopsis. TF-IDF, is a simple way to pull unique keywords out of a document by subtracting common words from another document (or set of documents). There are other much better algorithms for keywords, but this one works pretty dang well for how simple it is. I doubt Google uses TF-IDF anywhere directly, but that doesn't mean you can't use it to find interesting new keywords.
My tool does have some limitations.
- You can only use one other URL. I'd suggest using the top results from the SERP for your topic.
- I forgot to implement stop words
- Both crawled pages must have some good crawlable content
- I did not test my code very much
I'll try to answer questions or implement changes. Hopefully, this helps someone.
