Which plugin do you use for auto-tagging posts?

I am thinking about creating a new auto-tagging plugin for WP. I checked several plugins but none of them was so good as the one in my head. So if I won't find a decent plugin I will make my own.

Thanks for your answers.

 

Hi ,
I use , it auto tags based on content before you press Publish. I find it excellent.

Hello, thank you for responding.

I finally released my plugin Automatic Post Tagger. It does not use external API, it adds tags from your own list of tags (related words and many other features supported) so I think that you might find it useful.
