Pretty limited...

This can't be your only thesaurus if you're interested in genuinely exploring the words behind a concept that's on the tip of your brain. A few common words have a nice range of suggestions, but it wasn't the kind of broad spectrum of esoteric associations implied in the picture for what I've tried so far.

Ex: "Critical = decisive, vital" … If either of those were helpful then it's seriously unlikely that a thesaurus is going to make the difference in polishing up whatever it is you're writing.

I wish I could be more specific, but I can't find the words. If only I had good thesaurus. :-/

Extraordinarily Useful — Better Than a Thesaurus

Major Addition to Review. To use this app make sure to read the definitions of the selected words. Otherwise you may make the mistake of thinking the app relates Muslims to assassins in a modern social sense, as one example. That is simply not true. Make sure you read the definitions to make the best use of the app. The definitions are important.

Nisus Thesaurus is not a synonym finder, like a normal pedestrian thesaurus. It is actually better, if you care about interestingly concise communication.

Nisus Thesaurus relates words by concept more than by equivalence. For example, Looking up "intelligent" provides pathways to words related to "reasoning," "thinking," and "well-informed," plus "healthy," "level-headed," and "sound," the final one being good judgement.

The software benefits writers by suggesting alternative ways of viewing and understanding their research. It helps writer communicate with more clarity.

Nisus Thesaurus uses the WordNet database from Princeton University. It is an incredible tool for helping you create and refine your writing. Use it alongside a traditional thesaurus and dictionary to enrich your communication skills.

In defense of Nisus, from a marketing point of view, calling it a thesaurus makes sense, but it is much more than a synonym finder.

If you just want different ways of saying things, you might consider the excellent Oxford dictionary and thesaurus built into Mac OS X.

best choice for non-native speakers

Nisus Thesaurus has several features that make it the best choice for non-native speakers. The old-fashioned style of thesaurus is not very helpful for English learners because they typically don't know the meaning of the suggested synonyms and so end up choosing a word that doesn't make sense for their particular context. Nisus Thesaurus, on the other hand, provides a list of possible meanings for the word you look up, and then makes it clear which synonyms are appropriate for which definition. Even better, it lets you choose 'more specific' or 'more general' synonyms, so a non-native speaker can avoid choosing a word with an overly narrow meaning.

I have recommended this thesaurus to my international students, but I was disappointed to discover that they can't use it on their smartphones. Please make this thesaurus available as an app for iPhone and iPad!!!!!!
