Read-only by design. This agent has no path to sending, spending, publishing or committing anything. Where that limit is the product, removing it would remove the reason to trust the output.
Overview
Generic AI writers produce beautiful property copy containing features the property does not have. In most markets that is not a style problem — inaccurate particulars are a regulatory one, and the agency carries it.
This agent writes only from the facts you give it. Anything it was not told is either omitted or listed as missing, never filled in. It separates the description into what is verifiable from your data and what is subjective framing, so a compliance reviewer can see the difference at a glance.
It produces the whole set an agency actually needs: a portal description at the right length, a short social version, a headline, and the structured fields most portals require — in as many languages as you sell in, written natively rather than translated word for word.
Benefits
Listings live the same day
The bottleneck moves from writing to photography.
0 invented features
Nothing to retract
Copy that cannot claim a feature the property lacks.
One property, every market
The same flat presented natively to buyers in several languages.
What it does
Writes only from your facts
Every claim traces to a field you supplied. Nothing is invented to fill a gap.
Flags what is missing
Tells you which fields would strengthen the listing rather than guessing them.
Separates fact from framing
Verifiable statements and subjective language are listed apart, so compliance can check one and ignore the other.
Refuses the risky adjectives
No investment promises, no guaranteed returns, no claims about neighbourhood character that attract discrimination complaints.
Native in every language you sell in
Written in each language, not translated from English.
The full set, once
Portal description, headline, social version, and the structured fields portals ask for.

Why Real estate in particular. It writes from the property's real attributes, so nothing in the listing is a claim a buyer can hold you to.
Runs unattended
Started by you or by an event, and it finishes on its own. Nothing waits for someone to be at a desk.
The same standard every time
The two-hundredth item is held to the bar the first one was. Consistency is the part people cannot sustain.
It cannot act on its own
Real Estate Listing Writer has no path to sending, spending or committing. That limit is why its output is safe to act on.
How it runs
This agent runs server-side through the PROMIVO runtime. Each run is logged step by step and every tool call is permission-checked before it executes.

FAQ
Will it describe features I did not mention?
No. That refusal is the point. Anything you did not supply is listed under missing information instead of being invented — which is what makes the output safe to publish.
Can it write in Arabic, Turkish or Russian?
Yes, and natively rather than by translation. Property vocabulary and buyer expectations differ by market, and a word-for-word translation reads as foreign to the buyer you want.
Why does it avoid words like 'family neighbourhood'?
Language describing who a neighbourhood is for attracts housing-discrimination complaints in several jurisdictions. The agent describes the property and verifiable amenities instead.
