Real estate agents use Kortex, a Chrome extension for Gemini Notebook (formerly NotebookLM), to keep a notebook per buyer, listing or neighborhood with listing details, local Reddit threads, news and YouTube tours. They ask it to compare homes with each detail cited, draft copy from saved prompts, and export a PDF for the client.
Kortex sends what you import to Gemini Notebook in your own Google account; Kortex itself doesn’t keep your chats or the contents of your sources. Follow your brokerage’s policies before adding clients’ personal or financial details, and check AI-drafted listing copy against fair housing rules and your MLS’s rules before it goes out.
Your edge is knowing the area. Kortex keeps that knowledge where you can use it.

“I am not very tech-savvy, but the Kortex extension is easy to use. I save recipes and cooking notes from different websites, and everything stays in one place. Earlier, I used to forget where I saw a recipe; now it's easy to find. Saves time and effort.”
