Google Search Now Supports Connected Apps for Personalized, Cross-App Retrieval

Google has expanded its Connected Apps feature for Search, allowing users to link third-party applications so that Google Search can retrieve and surface personalized results from those app data sources alongside web results. For developers, this is significant because it extends Google's retrieval surface into private data domains — a move that could compete directly with enterprise RAG deployments that aggregate personal or organizational data for AI-powered search. The architecture implies that Google is building a permission-scoped retrieval layer that bridges public web index and private app data, which is a meaningful infrastructure play that developers building competing search or assistant products will need to track. If widely adopted, Connected Apps could reduce the need for custom integrations between AI assistants and SaaS tools by centralizing that retrieval through Google's index. Developers building apps should also consider what it means to be a data source that is (or isn't) connected to this ecosystem.
