Signal Interview-built conversational replicas of the deceased

Summary

This signal is the posthumous bot, an application that interviews a living user in order to build a highly realistic digital persona. After the person's death, that persona can go on interacting with others on their behalf. Sitra cites the service HereAfter, dated April 2025. The recordings become the raw material for a conversational replica that relatives can keep talking to. It turns memory into an interactive product and raises questions about how grief and remembrance will change. In Sitra's imagined 2046 magazine, curating personal data for a virtual afterlife is part of preparing for death, and this signal is one of its real-world anchors.
