ChatGPT now lets you upload and work with files directly in conversations. You can drop in spreadsheets, PDFs, Word docs, images, and more to analyze, edit, or generate content on the fly. Just open the tools menu, pick “Add photos or files,” and ask ChatGPT to summarize reports, visualize data, rewrite documents, or extract key details into tables. Some versions also connect to third-party apps via Settings → Apps, allowing you to bring in external tools for richer interactions. For Enterprise users, admins control app availability, and data accessed through apps isn’t used to train models by default. This turns ChatGPT from a chat tool into a practical workspace where you can get stuff done without switching contexts. Why it matters: This shift from pure conversation to document-centric task handling marks a major step toward AI acting as a real productivity partner, not just a fancy Q&A bot.
