Google is enhancing its AI Mode on desktop by adding image and PDF upload capabilities. Users can now ask detailed questions about uploaded images, similar to the existing mobile functionality. In the coming weeks, PDF uploads will be supported in the US, allowing users to summarize lengthy documents and ask follow-up questions. AI Mode will cross-reference uploaded materials with web information, providing responses with links to its sources. Support for additional file types, including those from Google Drive, is planned for future updates.
