Clue is a simple, quick and enjoyable way to learn new things. The application presents a searched item by a picture and 3 key words. The key words are related to the searched item by association. Once these keywords are shown, the user can ask for an alternative word or for a word definition.
How does it work? Clue uses Markiv Chain algorithm that summarizes a wikipedia theme into few words. Search results are also compared to Google results to allow relevant and updated associations. In addition, the application saves data to allow better search results in the future.
