Casa is an AI-powered property platform that fundamentally changes how people find rental homes in London. At its core, it's a sophisticated system that continuously monitors the entire rental market across all websites and platforms, using artificial intelligence to filter out scams and low-quality listings while identifying properties that match users' specific needs. Unlike traditional property sites that send daily email digests (which are practically useless in a market where properties vanish in 46 hours), Casa sends instant WhatsApp notifications the moment a suitable property appears. The AI understands detailed preferences about locations, amenities, and property features, going beyond basic criteria like number of bedrooms or price range. This means renters receive genuinely relevant matches in real-time, giving them a crucial early advantage in London's brutally competitive rental market. The platform combines two key innovations: comprehensive market monitoring that catches every new listing as it appears, and intelligent matching that ensures users only get notified about properties they'll actually want to view. Casa's technology essentially acts as a personal assistant that never sleeps, constantly scanning the market so renters don't have to repeatedly check multiple websites or miss out on their ideal home. The service is free to use, with a premium Casa Plus feature that provides additional capabilities and enhanced notifications.
