Drag'n'Keyword
This Windows tool generates a list of keywords from a given HTML file. The file can be simply dragged on the window and all found keywords are displayed as a comma separated, alphabetical ordered list. This list can then be used in the file's META-tags.
It works only with german files, as it recognizes keywords by a capital first letter (In german each noun starts with a capital letter). Words that shouldn't recognized can be excluded by a rightclick. These stopwords are saved in an .ini-file.
