Haven detects the language of your property the first time you import it (whether by URL or via a connected PMS like Hospitable) and stores it as the property's canonical language. From then on, every Haven AI writing assistant — the per-field assistants in your editor, the edit-property AI chat, and the background enrichment that fills in missing details — generates content in that same language.
The setting is per property and per multi-unit site. Today it controls AI generation only; existing scalar fields (title, tagline, description, etc.) stay exactly as you wrote them.
Haven supports five languages for AI generation:
Properties whose language can't be confidently detected — usually because there isn't enough text yet — default to English for AI generation. You can change this any time from the editor.
Edit listing > Settings > Language
You'll see a single-select list of the five supported languages. The currently selected option is the language your AI writing assistants and enrichment tasks use for this property.
The same section has a Re-detect from property content button that runs language detection over your title, tagline, description, and details markdown and updates the setting accordingly. Use this if you've rewritten major sections of the property in a different language and want Haven AI to follow.
Multi-unit site editor > Settings > Language
Multi-unit sites have their own language setting that controls the AI assistants for the page name, tagline, description, the SEO meta description, and the smart property cluster names you see when grouping properties.
When a multi-unit site is created from a set of attached properties, Haven infers its language from the most common language across those member properties. If the properties are split, the most common one wins; ties resolve to the first property in member order. We deliberately do not recompute this whenever you add or remove a member property — that would surprise you mid-edit. The Settings panel includes a Re-infer from properties button if you want to refresh it explicitly.
Setting a non-English language conditions every AI prompt Haven sends on this property's behalf. That includes:
The language setting only affects future AI generation. It deliberately does not:
If you need to update existing content in your new language, edit the fields directly or use an AI assistant in the editor.
When you switch the property or multi-unit site language, Haven shows a confirmation modal explaining that the change only affects future AI-generated content. You can cancel from the modal. The change takes effect on the next AI request — no rebuild or background job is required.
This is the first stage of broader multilingual support for Haven. Soon you'll be able to keep a canonical language for your property AND publish localized versions of the public page (with proper hreflang tags and per-language URLs). For now, keep this setting pinned to the language you actually write your property in so AI never silently translates your work into English.
