Ithaca is a pre-living agent for your next home. While looking for our first home in South Korea, I felt caught between rental-deposit fraud concerns and pressure to buy. But even without fraud, a home can take years of savings and still fail to fit our daily lives. Ithaca lets a household simulate 30 days in two candidate homes before deciding. Users describe their budget, schedules and preferences, then review an agent-generated plan. The simulation follows workdays, remote days, errands and walks across roughly four weekly cycles, revealing how everyday differences add up. Users compare estimated commutes and monthly costs, inspect the sources and assumptions behind each result, and follow recorded journeys in 3D. The goal is to discover trade-offs and prepare better questions for a real viewing. Ithaca turns a housing decision into a household-specific, inspectable comparison.
