About this tag
Cross-document analysis on WindowsForum.com covers Microsoft Copilot's ability to synthesize information across multiple uploaded files in a single request. Recent discussions highlight how Copilot on Windows 11 and the web can now analyze up to three files at once, enabling multi-file reasoning that previously required manual collation or third-party tools. This capability represents a shift from treating each file in isolation to performing cross-document synthesis, a feature comparable to ChatGPT-style multi-file analysis. The tag focuses on Copilot's evolving role as a system-level assistant for productivity workflows involving multiple documents.
