What capability does the Research Tool in Google Docs provide?

The Research Tool in Google Docs is a powerful feature that facilitates web searches for information and citations directly from within a document. This tool enables users to look up facts, definitions, and resources while they are writing, saving time and allowing for a more integrated research process. Users can easily access reliable information from the web, incorporate it into their documents, and even generate citations in various formats without needing to switch between applications. This makes it particularly useful for students and professionals who need to include accurate references and research findings in their writing.

While conducting online polls, tracking changes, and providing spell-check features are important functionalities, they are not the primary capabilities of the Research Tool. Polls are typically created using other Google tools like Forms, tracking changes is part of the version history feature, and a spell-check is integrated into the editing tools of Google Docs. Therefore, the ability to perform web searches and obtain citations stands out as the defining feature of the Research Tool.
