14 DAY TRIAL // Called the Watson Tone Analyzer, this supercomputer can interpret a text you input into it by performing a "tone check" to analyze three aspects of it: emotional, social and writing style.
After doing your "tone check," it will be able to divide it into further categories and tell you if your style is confident or not, or whether the emotional tone is cheerful, angry or negative. Afterwards, it will give you an overall tone and, impressively enough, it'll suggest how to fix it.
The use of this machine is to better communicate with either your superiors, your colleagues or your clients. To write a letter or any sort of message that will convey your perfect message through the tone of your selected words. It won't write your letter for you, but it will present you alternatives that are organized by colors and segments in order to fine tune your expressions.
However, it is not without limitations. It cannot find humorous suggestions nor can it do metaphors. Also, it doesn't understand sarcasm, humor and other styles, and just picks out individual words to determine the tone. It will only give you synonyms that are adequate to what you'd need in the Cheerfulness, Agreeableness, Conscientiousness, Openness, Analytical, Confident and Tentative segments of words.
Watson can help you make the perfect dry letter for your boss, but it would be a disaster to count on it to write to your friends or family.
