The Athens Chatbot Hackathon is inviting all cities around the world to build applications utilizing chat, messaging, and other natural language interfaces such as voice to interact with people, brands, or services and bots in the conversational commerce space. You could use bots to integrate with other services, post comments remotely or control a smart home, create custom tools providing you with alerts, weather forecasts, translations, or other services upon request, build single- and multiplayer games, build social services, or anything else that is virtually anything else!
