Does the AI ever make things up?

No. We use Retrieval-Augmented Generation with hard guardrails: if a fact is not in the listing's documents, the model will say so. Every fact in a reply links back to its source.

Who trains the AI on my listing?

You don't — the platform does. Upload the deed, the energy certificate, HOA minutes and the floor plan. The AI Twin builds itself from those files in minutes.

Which languages does it speak?

German and English are native. Spanish, French, Arabic, Italian and Portuguese are produced via AI translation with the same source citations.

Can owners see what buyers ask?

Yes. Question history is a private dashboard for the owner. It shows top questions, top concerns, and the AI's reply — so you know what to fix in your listing.

Is the AI Twin GDPR-compliant?

Yes. All inference runs on AWS Bedrock in EU regions. Documents are encrypted at rest and in transit. Owners can purge the index any time.

Anatomy of the feature

How the AI Twin works

Bedrock + RAG. Trained on the listing's real documents. Source-cited on every reply.

Trained on real docs

Deed, energy certificate, HOA minutes, floor plan, host description — all ingested via Bedrock + RAG.

Source-cited answers

Every reply names the document and the page. Buyers can verify in one tap, without leaving the chat.

Question history per listing

Owners see what every prospect asks. Free market intelligence that no portal offers.

AI Pricing Coach

Sees comparable listings around you and recommends a list price that actually sells, not one that lingers.

Deeper look

Why a Twin beats a portal Q&A

A portal Q&A wastes 18 hours per listing. The Twin reads the deed once, then answers forever — with a tap to the source page.

Reads the deed, energy certificate, HOA minutes and floor plan at upload.
Replies in seven languages with the source document linked on every answer.
Refuses to invent — when the documents stay silent, the Twin says so.
Tracks which questions came up most so the owner knows what to update.

I asked the Twin about the energy rating at 11:42 pm. It linked the Energieausweis page, said class B, valid until 2031. The seller never had to wake up.
