Trialled across the prison estate, having analysed over 8.6 million messages at the point of announcement in July 2025.\n\nAnnounced alongside a separate AI violence predictor, described as analysing factors including a prisoner's age and previous involvement in violent incidents in custody to predict individual risk and assess threat levels on wings. That second tool is recorded here as announced rather than deployed: the announcement does not state it has been trialled, and no deployment evidence has been found.\n\nBoth rest on a single official source.",
