Population service of the canton of Vaud

The Population Service of the canton of Vaud (SPOP) is responsible, among other things, for implementing legislation on migration (foreign nationals and asylum seekers). Given the complexity of this area and the constant changes to the law, the SPOP wanted to set up a tool to test eligibility for a permit. We created a multilingual chatbot that uses simple questions to explain the steps to be taken in each situation to apply for a residence permit. The challenge was to cover the entire field in the bot, while supporting users with the smallest possible number of questions.
