Two things happen. First, a TabPFN-3.5 model trained on the 891 passengers whose fate is recorded gives you your chance of surviving the night, plus a few what-ifs ("if you had been travelling alone", "if you…
In April 1912, the web application Titanic Séance invites users to imagine themselves as one of the 891 passengers aboard the ill-fated ship.

Users can then hear from a real passenger whose information most closely matches their own, as spoken by the Gemma 4 language model. This interactive experience was developed as part of the DEV Hacktoberfest 2026 Ghost in the Machine challenge. The app's creators have put significant effort into ensuring accuracy and empathy in the responses, carefully selecting which personal details the AI can share and teaching the model to avoid inventing false memories.
