Ghost of the City is a psychogeographical agent. It runs on AWS Lightsail, with a Rabbit R1 acting as a push-to-talk voice interface and a private journal webpage that auto-generates from each walk. The stack is custom: an OpenClaw voice gateway connecting to Claude Sonnet, a context engine that holds the history and geography of each route, and a chronicle renderer that turns a walk into a private document. Each exchange is captured with GPS coordinates and weather data; the journal renders automatically, most recent walk first. The agent cross-references a datafile of known London psychogeographical sites as it responds, and can suggest drift directions based on buried rivers and Roman walls.
The voice and sensibility of the agent are deliberately tuned to a specific lineage: the writers who have treated London as an object of deep reading — Sinclair, Ackroyd, Sebald at one remove, the Situationist drift as a method. The agent knows this tradition and operates within it without performing it.
A research project disguised as a side project: a way of working out what an agent that is always on, and always knows where it is, feels like with no product constraints on it. And what a companion sounds like, as opposed to an assistant.
The project ran in London between March and September 2026. The server has since been decommissioned and the whole thing is archived publicly on GitHub: the persona brief, the sample data file, the capture and rendering scripts, the Chronicle of every logged exchange, and the journal page exactly as it was served.
