My vote is to build your headlines yourself. I am sure some code can be compiled to generate some pretty good headlines, but you are the one who knows where and what you want the reader to experience.

Write 100 headlines. Test your top 20. There ya go.

-Scott

I haven't seen a software, but for aspiring copywriters who don't feel like writing out 100 headlines for one product (which is so friggin hard) that could be a great investment. Go make this software! Gogo!

Michael, try this. Go to EzineArticles do a search for your keywords. Open an article, scroll down to the bottom and look at the titles of the most viewed and most published articles. Use those titles to spur your imagination, because you know they are working.
