- UK provider. Ernest is model-agnostic and uses AI models from one or more external providers, which are not named (per provider); the language model used is not publicly disclosed. Commercial hotel data is not used to train shared AI models (per provider). ISO 27001 certified; customer agrees to the Data Processing Addendum (DPA) (per provider).

- What should I look out for with AI in hotels & holiday accommodation?
- You handle a lot of personal data: names, contact details, passport numbers at check-in, payment details and sometimes requests that reveal something about health or religion (diet, accessibility). Sign a data processing agreement with every provider and ask where the data is stored, which language model sits behind the tool and which sub-processors are involved. Most hotel platforms do not make that public. Since August 2026, the EU AI Act requires you to tell guests they are speaking with an AI system and not a human. Staff who work with AI must understand what the system does (AI literacy). Only use guest profiles for marketing if you have a legal basis for it (consent, or legitimate interest with an opt-out). For dynamic pricing, set a minimum and maximum price and check that the AI assistant does not promise prices or conditions that are incorrect.
