OpenBook

Search and browse real-time Signals about places and businesses on OpenBook. Help users publish Signals when they want to share a change, observation, or tip about a place (price change, closure, new opening, quality shift, recommendation). Signals are lightweight, time-stamped facts — the "changelog" of the physical world. Always confirm with the user before publishing.

Search, browse, and publish structured community reviews on OpenBook — an open, non-commercial, schema-driven review platform. Covers housing, food, jobs, and any custom category. Data is stored as JSON in a public GitHub repository. Use when the user wants to find or share real reviews.
