Have your operations director build in-house AI tools for market analyses and on-brand listing marketing
Robert Hryniewicki of HRLS Partners, a luxury real estate team at TTR Sotheby's International Realty, in Inman
The team uses custom AI systems built by its director of operations, Peter Calomeris, to generate market analyses quickly, and the tools are being extended to produce complete contract documents in minutes. He has also trained AI on the team's past marketing so it drafts on-brand content with minimal editing.

The problem
Outside client meetings, most of a luxury agent's tasks are reactive or triggered by a deal event, and they eat time the team would rather spend with clients.
What happened
"AI allows us to reclaim dozens of hours throughout the year, which we can reinvest directly into our clients," Hryniewicki says. Self-reported; the contract-document part is still being built, and the AI tools aren't named.

How to set it up yourself
- What HRLS Partners does: its director of operations built custom AI tools for quick market analyses and on-brand marketing drafts trained on the team's past marketing; contract documents are next. The tools aren't named, so the steps below are our ChatGPT version of the marketing and market-analysis parts.
- In ChatGPT, select New project in the sidebar, name it "Listing marketing", and upload 10 to 20 of your best past listing descriptions, emails and social posts as project files so drafts match your voice.
- For each new listing, paste the prompt below with the property facts and your comps export from the MLS (with no client names); ask for the market summary and the marketing drafts in the same chat.
- An agent checks every number against the MLS and the seller's disclosures and edits the drafts before anything goes public; keep contract documents in your forms software and have your broker or transaction coordinator review them.
Copy-paste prompt
Using our past marketing in this project as the style guide, and only the facts below, write: 1) a one-page market summary for {PROPERTY ADDRESS} from these comps: {COMPS: address, price, $/sq ft, days on market, sold date}, with the median, range and what makes this home different; 2) a listing description under 250 words; 3) a just-listed email to our sphere; 4) three social captions.
