I like how easy it was for me, as an inexperienced developer (I have only been programming in Python since last year), get up-and running quickly using this service - no coding experience required! The documentation could be better at times but once you've figured out what's going wrong things work well enough if there are any issues or questions about something specific then Stack Overflow can help resolve most of them very easily indeed :) Would definitely recommend anyone who wants some fast results without having much development skills/experience needed here :).
Automated sentiment extraction from social media posts; automatic translation between two languages via machine learning models available through Google Translate APIs which were not accurate nor reliable when used directly by myself so had little choice other than use one provided instead ;-).
