Relative keyword tool

Hi, can any1 tell me where can I get the relative keyword tool
i.e gives all the relative words for all (most of the) the words in the dictionary (without requiring specific user input)

either it can b even a text file (like in VERB OCEAN), but i need it for all the words not only for the verbs

Any sort of help would be greatly appreciated

The wordtracket tool will give you a list of related words to your Kws...

Also I hope this one too:

but do u know any tool tht gives the list of all relative words for each word without specifing any keywords. In word tracker we've to give the keyword and based on tht it gives the relative words, but i need relative words for all the words without specifing keywords.
