What languages does Rezi support?

Rezi handles 20+ languages automatically. When a guest texts or calls in Spanish, Mandarin, Portuguese, or another language, Rezi understands them and replies in that same language, no setup required.

There’s no language toggle to configure, no per-guest setting to remember, and no translated copy of your knowledge base to maintain. Language handling is built into the same understanding layer that powers everything else: the AI works out what’s being asked regardless of the language it arrives in, finds the right facts, and writes the reply in the asker’s language. For many hosts this quietly removes one of the biggest communication barriers in short-term rentals.

How it decides which language to use

• It detects the language of each incoming message and matches it
• A guest can switch languages mid-conversation and Rezi follows
• Your knowledge base can be written in one language and still answer questions asked in another

That last point surprises people, so it’s worth spelling out: retrieval works on meaning, not words. A question in Spanish about “la lavandería” matches your English entry about laundry hours because the system compares what the message means, then the reply is composed in Spanish from your English fact. Write your knowledge base once, in whatever language you think in, and it serves every guest.

What this looks like in practice

A guest texts “¿cuándo recogen la basura?” and gets back the trash schedule in natural Spanish, drawn from the same entry that answers English speakers. A guest from São Paulo calls about check-in and hears the answer in Portuguese, see voice languages for the call side. If a bilingual party switches between languages mid-thread, Rezi simply follows, each reply matches the message it’s answering.

Escalations keep you in the loop regardless of language: when a conversation in another language reaches you, the thread is there in the Interactions view, and the AI’s handling up to that point gives you the context. Emergency detection also works across languages, “fuga de agua” trips a water-leak escalation just as “water leak” does, see emergency handling.

Edge cases worth knowing

Coverage is strongest in widely spoken languages, Spanish, Portuguese, Mandarin, French, Vietnamese, Tagalog, and the rest of the top twenty-plus, which covers the overwhelming majority of real guest traffic. Very short or mixed-language messages (“parking donde?”) are handled by meaning like everything else. If you ever spot an awkward reply in a specific language, treat it like any wrong answer: check the underlying entry, and report it to support if the facts were right but the language was off.
