Request demoWhat makes a good property description
Before comparing tools, we need to know what we are looking for. A quality property description has:
- A hook in the first line: the sentence that engages the buyer before they read the rest.
- Technical data integrated naturally: square metres, bedrooms, orientation without sounding like a spec sheet.
- Local market vocabulary: "bright", "well connected", "established neighbourhood", "move-in ready".
- Energy certificate mentioned: mandatory in Spain and expected by buyers.
- CTA at the end: a call to action inviting contact or a viewing.

ChatGPT: powerful but requires well-built prompts
ChatGPT generates excellent text when given the right AI prompts for property descriptions. The problem for the real estate agent is that building a good prompt takes time and knowledge. Without a specific prompt, the text tends to be generic ("spacious apartment with bright rooms") rather than specific and persuasive.
If you have time to learn how to write good prompts, ChatGPT is a very powerful option. If you prefer a solution with no learning curve, there are more direct alternatives.

Why specialised tools win on speed
The key difference between generic AI content generators for real estate and a specialised tool is the input form. In SnapHouse, the agent fills in a form with property data (square metres, bedrooms, orientation, area, price, energy certificate) and the AI generates the description directly. No prompts, no copy-pasting.
For 20 properties per month, the time difference is significant:
- With ChatGPT and manual prompts: ~3 minutes per description × 20 = 60 min/month
- With SnapHouse: ~45 seconds per description × 20 = 15 min/month

What is the best AI tool for property descriptions?
It depends on volume. For a one-off property, a general model with a good prompt is enough. Past a few a month, a tool that also produces the PDF and social pieces pays for itself.
Do general models understand the Spanish market?
They understand the language, not the format. You have to tell them explicitly about the energy rating, the structure portals expect and the tone, or the text reads translated.
How much quality difference is there between tools?
Less than you would think on the text itself. The real difference is how much work they save around it: formats, images, PDF and publishing.
Does the result change much depending on the tool?
On raw text, less than expected. The gap opens on what comes next: whether you end up with the sheet, the carousel and the Reel ready, or just a paragraph.
