I am looking for an intelligent keyword harvester

Hello all,
I’ve been browsing all day the internet, trying to find an intelligent keyword harvester tool that I would use for harvesting all pages on my own website for keywords and key phrases.
Of course best way is to sit down and spend some hours if not days trying to create best keyword for my website pages.
But I decided to use a simple method of automatic harvesting, and I know there are tools like that. I just wasn’t lucky enough to find one good.
Anyone have any ideas of a really good and smart keyword-harvesting tool?
A tool that would find keywords, sort them, organize well, make them meta tag ready, eliminate single-words duplicates, etc.?
Thank you a lot.
