Analysis
Graylark Technologies' AI tool Raven can now identify the exact short-term rental, house or hotel room shown in a single interior photo, with no location metadata required, and two U.S. police departments are already using it. The Los Angeles Police Department and the Miami-Dade Sheriff's Office, which trained a custom model on county properties, are both confirmed users, 404 Media reported Monday. CEO Daniel Heinen said the company is "investing heavily" in interior geolocation across U.S. hotels, short-term rentals, houses and apartments.
Raven is a rebrand of GeoSpy, the tool 404 Media first exposed in January 2025. The tool was open to nearly anyone back then, and some users in the company's Discord asked for help stalking specific women. Graylark locked it down to government and enterprise accounts after that reporting, and Heinen now pitches it mainly for trafficking and exploitation investigations.
How Raven finds a room
The system was trained on millions of images and cross-references a submitted photo against listings on Airbnb, Zillow and Vrbo rather than reading EXIF data or GPS tags. In demos, it matched a Charlotte, North Carolina Airbnb, a Montecito, California Vrbo rental, a San Francisco house tied to Zillow photos, and a hotel room. Heinen described the moment his team realized the tool worked on interiors, not just exteriors, as "kind of an 'Oh shit' moment for us."
Raven sits inside a loosely regulated niche of AI tools that infer real-world location from ordinary photos rather than faces. Clearview AI built a facial-recognition business on a similar scrape-first model and has faced lawsuits and regulatory fines across multiple countries as a result; PimEyes does something close for faces rather than property. Graylark's bet is that interiors -- countertops, light fixtures, floor plans -- are a richer and less-regulated signal, and that rental platforms have far less leverage than individuals to stop the scraping. Graylark hasn't disclosed a funding round, but Heinen said on X in September that Alexandr Wang, now head of AI at Meta, is an angel investor; Wang did not respond to a request for comment.
The gap between the pitch and the results is the story critics will seize on. Miami-Dade Sheriff's Office spokesperson Joseph R. Peguero Rivera told 404 Media that use of the tool has been "limited and largely exploratory," with no arrests or breakthroughs tied to it so far. Airbnb says it has no relationship with Graylark, strips location metadata from its own listings, and is reviewing the report; Zillow says scraping violates its terms and it pursues legal action when warranted. Vrbo didn't respond to a request for comment.
Two police departments are testing the tool, and an AI lab executive is personally funding it, before any of those disputes have been resolved. The data-provenance fight, not the model's accuracy, is what should worry anyone backing or buying this category next.
