Karpo is developed by MachinePulse Pte. Ltd., an AI city concierge running on Apple iMessage, focusing on no active search and proactive personalized local lifestyle proposals. Its core coverage includes New York, San Francisco, and London. Unlike traditional local lifestyle apps, it does not require launching a separate application, but instead allows interaction directly within daily chat windows, continuously optimizing recommendation accuracy based on user location, time, and historical preferences. It also integrates mainstream booking channels such as Ticketmaster and Viator, achieving a closed loop from recommendation to purchase. The product is positioned as a lightweight city life planning assistant, solving user problems like switching between multiple apps, spending time searching for guides, and difficulty in reaching consensus on group outings. It has no complex paid packages and offers completely free basic functions. However, it is limited in geography, only supporting a few overseas cities fully, and non-supported areas will directly restrict service access. Its core strengths lie in four capabilities: conversational interaction, personalized continuous learning, group collaborative planning, and one-stop event booking, lowering the planning costs for urban travel, socializing, and leisure.
