I'm totally new to TensorFlow and ML in general, but I've been curious about how this could fit into a system.

Say you need a CNN text classifier algorithm to categorize simple single page documents. So you set one up via TensorFlow, train it with a big dataset, and get it outputting categories with decent accuracy. Could you then use some type of API and query it from a (low traffic) production web app?

Or is it more for the research phase rather than real-time interaction?
