Google just upgraded Gemini Deep Research, its most advanced AI research agent, and this time the upgrade isn’t limited to Google’s own products. Google says its AI capabilities may soon be available in the everyday apps you already use. With the introduction of the new Interactions API, Deep Research is no longer an exclusive Google feature. It can now be integrated directly into third-party apps, opening the door to a wave of tools on your phone to quietly achieve far more powerful AI.
Gemini Deep Research is designed for long, complex tasks that many chatbots often struggle with. Instead of answering a single question, it works like a real researcher. It plans what information it needs, searches the web, reads through the results, identifies gaps, and then continues the search until a complete, informed answer is produced. As its reasoning engine, it uses Gemini 3 Pro, which Google says is the most factual model yet trained to reduce hallucinations during long, multi-step tasks.
How this upgrade reaches your apps
With the Interactions API, any developer can now integrate this research agent into their own apps. Deep Research can read uploaded documents, combine them with public web data, and create structured reports with citations. Developers can also control the structure of the final output, request tables or formatted sections, or receive results in JSON for automation. These capabilities make AI suitable for automated analysis tools, financial workflows, scientific research aids or knowledge apps.
With this feature now available to developers, your favorite apps like finance, learning, and productivity platforms can leverage deep research behind the scenes. With Google Deep Research also integrated into apps like Search and Gemini, you may soon get richer, more in-depth answers without having to do the work yourself. Instead of manually checking multiple sources or switching between tabs, your apps could soon automatically merge checked information.
Google is also preparing to ship directly into products such as Google Search, NotebookLM, Google Finance and the Gemini app. As this technology sneakily integrates itself into the apps you already rely on, the idea of research will soon feel less like a chore and more like something your phone simply does for you.
