Haven detects the language of your listing the first time you import it (whether by URL or via a connected PMS like Hospitable) and stores it as the listing's canonical language. From then on, every Haven AI writing assistant — the per-field assistants in your editor, the edit-listing AI chat, and the background enrichment that fills in missing details — generates content in that same language.
The setting is per listing and per landing page. 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:
Listings 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 listing.
The same section has a Re-detect from listing 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 listing in a different language and want Haven AI to follow.
Landing page editor > Settings > Language
Landing pages 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 listings.
When a landing page is created from a set of attached listings, Haven infers its language from the most common language across those member listings. If the listings are split, the most common one wins; ties resolve to the first listing in member order. We deliberately do not recompute this whenever you add or remove a member listing — 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 listing'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 listing or landing page 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 listing 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 listing in so AI never silently translates your work into English.
