## AI overview

Day one of Replay '25 in London brought developers together for workshops and a hackathon. Seven teams explored projects across AI, visualization, finance, gaming, developer experience, batch processing, and microservice orchestration, then presented lightning demos including workflow visualizers, a Slack Support Bot, an AI Code Edit Loop, and a Temporal Auction System.
