A walkthrough of building a multi-user AI chat application for coordinating dinner plans. The app uses Convex as a real-time database, Anthropic's LLM for AI responses, and Google APIs for restaurant search and maps. Key features include synchronized UI across multiple users, AI tool calling for restaurant searches, real-time subscriptions for automatic updates, and server-side security for API functions. The tutorial covers architecture, setup with environment variables, message flow, AI integration with tool calls, and how the real-time database keeps all clients synchronized automatically.
