Lumina learns everything about a hotel: what guests write in their reviews, the brand guidelines, the competitors, the calendar of the destination, and what people search on Google and ask AI assistants. From that it writes the hotel's work: website pages and improvements to the pages it already has, articles, content briefs, newsletters and campaigns, in every language the hotel needs. Hotel marketing agencies use one workspace for all their hotels, so each one gets more marketing, more specific to it, without adding people. Hotels use it to keep their own website written and up to date. The team asks for changes in a chat, sees the result and decides. The same engine writes the public hotel guide on luminafrontier.ai, 313 hotels in 2 languages, and the study «Hotels in ChatGPT and AI Search: 3,288 Answers Tested».
