AI Chat
AI Chat builds on AI Describer but allows users to ask questions about their current view, past views, and nearby geography. The chat agent uses Google’s Multimodal Live API, which supports real-time interaction, function calling, and temporarily retains memory of all interactions within a single session. We track and send each pan or movement interaction along with the user’s current view and geographic context (e.g., nearby places, current heading).
What makes AI Chat so powerful is its ability to hold a temporary “memory” of the user’s session — the context window is set to a maximum of 1,048,576 input tokens, which is roughly equivalent to over 4k input images. Because AI Chat receives the user’s view and location with every virtual step, it collects information about the user’s location and context. A user can virtually walk past a bus stop, turn a corner, and then ask, “Wait, where was that bus stop?” The agent can recall its previous context, analyze the current geographic input, and answer, “The bus stop is behind you, approximately 12 meters away.”
