At least, its tiny playground. Let's learn and play Conversational Interfaces a little!
Entities are stuff that are important in a sentence in order to perform an action. We want them to be recognized and classified. Entities have a ID (i.e. ingredients) and contains a set of matches, which is a pair of some text (i.e. pepperoni) and its ID (i.e. ingredient1) that will be returned when found in a sentence.
Intents are actions you're going to perform. They have an ID (i.e. pizzaorder) and some sample sentences (usually called training data - i.e. "A cheese pizza, please") for each one. In this example, Bravey will try to guess the entities in your sample data but, in real life, you can define how many and which entities an intent and each sample can have. Moreover we've instructed this sample Bravey to automatically recognize numbers, times, dates and time ranges and to stem not-entity words, so variants like "pizza" and "pizzas" in your sentences will be recognized.
We're ready! Just try writing a sentence in the box. Bravey will try to guess intent and extract entities.
