OpenAI updates ChatGPT Deep Research with a full-screen report viewer

OpenAI is turning ChatGPT into a proper research desk. The company has released a major update to Deep Research, adding a built-in full-screen document viewer. Long analytical reports generated by the model will no longer get lost in the chat window. Instead, they open in a separate window with convenient navigation. An interactive table of contents appears on the left, and a structured list of sources on the right. It may look like a minor interface tweak, but it reflects a fundamentally different approach to working with information generated by artificial intelligence.

Deep Research is a feature OpenAI introduced last year in response to growing demand for in-depth data analysis. The tool lets ChatGPT automatically scan the internet, collect relevant information and compile it into a structured report on a chosen topic. Previously this was awkward, because reports landed in the chat among other conversations. Now users get a full workspace built specifically for reading and analyzing large volumes of text.

The new viewer solves several practical problems at once. First, it removes distractions. When a multi-page report sits inside a chat window, it is easy to get lost in the conversation. A separate window lets you focus solely on the content of the research. Second, the interactive table of contents on the left lets you jump between sections instantly, without scrolling through the whole document. Third, the source list on the right is not mere decoration but a critical element for checking facts and judging how reliable the information is.

But the update is notable for more than its interface. OpenAI has also expanded the capabilities of Deep Research itself. Users can now tell the model which specific websites to analyze when building a report. This turns ChatGPT from a black box that decides on its own where to look into a tool you can steer. An analyst can point the system at specialist resources, academic databases or statistical publications, in short, at the sources that are genuinely relevant to the task at hand.

Who benefits most? Primarily professionals who work with data: analysts, journalists, researchers and consultants. They constantly need to get up to speed on a new topic quickly, gather information from different sources and verify facts. ChatGPT with the new interface speeds up that process considerably. A report that once had to be assembled by hand is compiled in minutes, and every cited source can still be checked.

The update shows OpenAI listening to its users. The tool worked, but the interface was getting in the way. The company noticed and fixed it, and did so fairly elegantly. It is a strategy increasingly common in AI: companies understand that raw algorithmic power matters, but the practical usability of how people interact with that power matters just as much.

ChatGPT is gradually ceasing to be just a chat and becoming a full-fledged working tool for real tasks. Deep Research with its new interface is another step in that direction. And it looks like this is only the beginning.
