Google just upgraded Gemini Deep Research, its most advanced AI research agent, and this time the upgrade is not limited to Google’s own products. Google says its AI capabilities can soon appear inside the everyday apps you already use. With the launch of the new Interactions API, Deep Research is no longer a Google-exclusive feature. It can now be built directly into third-party apps, opening the door for a wave of tools on your phone to quietly gain far more powerful AI.
Gemini Deep Research is built for long, complex tasks that many chatbots tend to 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 results, identifies gaps, and then continues searching until it builds a complete, well-sourced answer. It uses Gemini 3 Pro as its reasoning engine, which Google says is its 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 plug this research agent into their own apps. Deep Research can read uploaded documents, combine them with public web data, and produce 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. Such capabilities make the AI suitable for automated analysis tools, finance workflows, scientific research aides, or knowledge apps.
Because this feature is now developer-accessible, your favorite apps like finance, study, and productivity platforms can start using Deep Research behind the scenes. Since Google is also integrating Deep Research into apps like Search and Gemini, you may soon see richer, deeper answers without doing the work yourself. Instead of manually checking multiple sources or switching between tabs, your apps could soon pull together verified information automatically.
Google is also preparing to ship it directly into products like Google Search, NotebookLM, Google Finance, and the Gemini app. As this tech quietly slips into the apps you already rely on, the idea of research may soon feel less like a chore and more like something your phone simply handles for you.
