Google has introduced a new feature in its Files app that allows users to ask questions about PDFs using the Gemini assistant. This feature requires a Gemini Advanced subscription and is available on Android devices. When summoned, Gemini will display an “Ask about this PDF” button, allowing users to query the file’s content. Other context-aware features of Gemini include supporting web pages and YouTube videos. The feature was first announced at Google’s I/O developer conference in May.
