Keyword finder, Long tail pro, keysearch are all crap. I tried them all and my advice to you is dont buy them. I really dont understand why BHW users are constantly saying that these apps will help you.
When you are a beginner and want to have a bunch of ulta low comp keywords do the following:
1. make a list of forums in your niche (google "niche" forums).
2. Take a trial on ahrefs or semrush.
3. put the url of the found forum in ahref/semrush.
4. look at what keywords the forum is ranking for position 1-5.
5. Look manually at the top 10 of these keyword. Is the title optimized, is it mentioned in the text, are there weak sites in serp (QA sites, forums, weak niche sites).
6. Write a great article without grammar issues. At least 1000 words to begin with, later on add more text if needed.
Doing this I rank very quickly in top 10. Sometimes you need more text or couple of backlinks to push to top 3, sometimes it just takes time.
