OpenAI’s Chromium-based ChatGPT Atlas browser is testing a new feature likely called “Actions,” and it can now understand videos too.
This is why some users are seeing ChatGPT generate timestamps for videos, especially on YouTube. Atlas is a web browser where ChatGPT is built directly into the browsing experience, so you don’t need to switch tabs, copy links, or paste screenshots just to ask questions.
With Atlas, you can ask ChatGPT for help right inside the page you’re viewing. It can understand what’s on your screen, explain content, help you research, and even complete tasks while you browse. If you turn on “browser memories,” Atlas can remember useful context from sites you visited earlier, like job posts or product pages you were comparing.
Atlas also includes an “agent mode,” which can open tabs and click through simple workflows for you. It comes with safety limits, especially on sensitive websites. Recently, users on X noticed a new “Timestamps” button in Atlas that pulls timestamps from YouTube videos into the sidebar, showing that the browser can now understand video content.
I suspect some video-understanding announcements are coming.

The new Atlas browser from OpenAI is already surfacing new UI affordances: timestamps on YouTube, review summaries on Amazon product pages, etc. When you click them, the browser sends the video or product link to GPT… pic.twitter.com/gakMRlKx8L
In its latest release notes, OpenAI said the update focuses on stability and smoother daily use. It fixes a memory overuse bug and adds better “what to ask next” suggestions when the ChatGPT sidebar is closed. There are also UI and tab improvements, including Tab Search showing your five most recent tabs and Cmd+K opening tab search. OpenAI has also confirmed plans to release ChatGPT Atlas for Windows 11.
