Delve by Sidewalk Labs

Delve, originally developed by Sidewalk Labs, was a generative design tool created to help real estate developers and urban planners make smarter, faster decisions during the early stages of site planning. The platform combined artificial intelligence with user-defined priorities—such as maximizing sunlight, minimizing costs, improving views, or increasing unit count—to generate and evaluate thousands of development scenarios within minutes. Each solution was optimized for both performance and user goals, making Delve a powerful tool for navigating complex trade-offs in urban development.

Delve stood out in the AEC-tech landscape for its ability to integrate multiple data layers—like zoning, climate, transportation, and real estate economics—into one cohesive, decision-support system. Its intuitive interface allowed users to adjust key parameters, instantly see the impact on design options, and choose a layout that best met their objectives. From developers and architects to city planners, Delve made it easier to visualize the long-term implications of design choices while streamlining the feasibility process.

In 2022, Delve was officially acquired by Google and absorbed into the Google Earth team. This transition marked a significant shift in the product’s trajectory. While many of Delve’s original generative design capabilities are no longer publicly accessible in the same form, elements of its technology appear to have been folded into new urban modeling and solar design tools within the Google Earth platform.

Now, when users visit Delve’s original site, they are redirected to a Google Earth page highlighting features related to solar potential and early-stage building performance assessments. These tools reflect the legacy of Delve’s focus on environmental optimization, though with a narrower scope and limited public access compared to the original offering.

Despite the shift, Delve remains an important milestone in the evolution of AI-powered urban planning tools. It helped pioneer the application of machine learning and performance-based design in large-scale development contexts. Its acquisition by Google signals both the growing value of generative design in tech-driven planning and the broader trend of major tech firms investing in tools that support smarter, more sustainable cities.
