Chatbotstrap is a web-based tool that allows you to efficiently collect training sentences for any chatbot project. Start by defining intentions (like "getting the status of an order") and scenarios for them (to put them in context).

The tool will generate a link that you can send to your friends, your co-workers or anyone else (including people from Amazon Mechanical Turk and Clickworkers). When they will open the link, they will be prompted with a fake chat window and the according scenarios.
