The announcement also describes the Colleague Knowledge Assistant, live since 2025, which helps UK employees retrieve information while supporting customers. It presents the broader rollout in the context of security and governance. It does not establish that every proposed application has been deployed or that other banks will reproduce the same outcomes.
