SF Generate Tags is a plugin that helps generate tags for posts. It scans the names of all attached images and/or the post content (text) and places the resulting tags in the built-in WordPress “Tags Widget” in the post editor. 
The plugin analyzes collected words and picks out the most suitable for tags. 
All tags are then sorted in descending order and posted into the Tags widget. 
If you don’t like a tag which has been discovered and want to delete them, you can just click the X button and save post without them. 
The plugin doesn’t mess with your existing tags. It preserves all your existing tags for the post. All the actions can be easily undone.
This plugin should work with any language. It’s filtering algorithm is designed for English. All other languages will have all the words be added as tags.
