"Since the mid-2010s, chatbots have grown in usage and popularity across the humanitarian sector. While this usage has gained traction, there is scarce information on the collective successes, risks, and trade-offs of this automation. This research addresses this gap, documenting chatbot deployments across the humanitarian sector and exploring the existing uses, benefits, trade-offs and challenges of using chatbots in humanitarian contexts. The research was conducted by The Engine Room, with support from the American Red Cross, the IFRC and valuable input from our advisory committee. This report is not created as a comprehensive overview of chatbots use, instead, the goal of the report is twofold: to offer guiding questions and considerations for humanitarian organisations deciding if a chatbot is an appropriate tool to address programme and community needs. It also contains use cases highlighting the experiences of practitioners working in diverse geographic contexts and issue areas." (Executive summary)
