Gemini Deep Research review

Gemini Deep Research is an agentic feature in the Gemini app. You type a question, it proposes a multi-point research plan that you can change, then it browses up to hundreds of websites, reasons over what it finds and writes a multi-page report in minutes. If you allow it, it also draws on your Gmail, Drive and Google Chat, which helps analysts combine public data with internal notes. You can upload your own files and turn finished reports into Audio Overviews, quizzes or interactive content in Canvas. Deep Research is listed on the free Gemini plan, and Google AI Plus at $4.99 a month doubles usage while Google AI Pro at $19.99 a month gives four times the free limits. Google lists it in 150 countries and more than 45 languages. For academic work, the weakness is that it searches the web rather than a scholarly index, so students should check that cited pages are primary sources.
