AI-generated Property Descriptions for Fastighetsbyrån

25 April 2025

Decerno has developed an innovative AI solution for Fastighetsbyrån, one of Sweden’s leading real estate agencies. The solution, called “The Typewriter”, integrates generative AI into Fastighetsbyrån’s brokerage system FasIT to streamline the creation of property descriptions. With around 40,000 homes sold annually, the solution has streamlined Fastighetsbyrån’s operations significantly. 

The Typewriter uses available data and images of the property to draft a description for the listing. Realtors can use the texts without altering them or as a starting point to continue refining them. The solution is based on generative AI and advanced image analysis, combining information from images with property data, Fastighetsbyrån’s guidelines and customized prompts to create accurate texts that highlight the unique characteristics of the property. After successful testing in 17 pilot offices during winter 2023, the Typewriter was launched in early 2024 for all Fastighetsbyrån offices. 

Decerno’s capabilities in AI and systems development of business-critical solutions played a crucial role in this assignment. The Typewriter is an example of how digitalization and AI tools can streamline workflows and contribute to a more modern and customized experience. Automating part of the real estate process frees up time for agents to focus more on providing advice and building customer relationships, while improving the quality of property listings. This contributes to a more innovative and efficient real estate service.
