The AI Hotel Landscape feed

Weekly snapshots of how 6 AI platforms (ChatGPT, Gemini, Perplexity, Copilot, Google AI Mode, Grok) recommend hotels across 56 destinations, from a 616-prompt corpus. Refreshed every Monday — the same data behind the live dashboard. Every endpoint returns JSON, or CSV with ?format=csv for spreadsheets.
