is joel madden dating nicole richie - Adult avatars and chatbots

Ana is a web-based chatbot for Copa Airlines that uses natural language.

You can ask Ana simple questions, such as what destinations Copa Airlines flies to or what Copa’s baggage allowances are, and she will respond within your web browser.

Users simply need to open Facebook Messenger (on the web or on a smartphone) and type in Expedia or @Expedia into the “To:” field.

You then tell the bot a bit about your travel plans, and the bot will follow up with questions.

Through Messenger, you can have your boarding pass delivered, you can request a seat change, and receive travel updates (such as flight status).
