Wolfram|Alpha is not exactly chatty, but it gives elaborate answers to factual and scientific questions on lots of subjects. For instance, asking 'what is the population of France?' gives you not only the current population (64.1 million) but also graphs with recent and long-term population history and age distribution, and also a list of the largest cities in France, with population numbers.
Wolfram|Alpha tries to choose the best representations for its answers. This can be text, but it also uses tables, graphs and pictures when appropriate.
Subscribing to Wolfram|Alpha Pro gives access to form-based Web-apps for a variety of subjects, like sun exposure, flight information, personal fitness, market quotes.
