Strongly agree with this — especially the framing around migration continuity.
I think this captures something that is easy to miss when comparing feature lists: Atlas didn’t just provide browser capabilities. It created a continuous way of working where browsing and an ordinary ChatGPT conversation shared the same context.
I raised a closely related feature request here:
Unfortunately, after further testing, the current ChatGPT Desktop app still does not fully preserve that workflow. In regular Chat, it can see that a browser tab is open and knows the URL, but it cannot actually read the page content. Full webpage context still requires switching into Work.
The Chrome extension has a similar limitation: browser context is routed through Work/Codex rather than an existing ordinary Chat or Project.
So I think your “please finish the last mile” framing is exactly right. The underlying browser technology may be there, but the continuity of the Atlas experience is not there yet.
I really hope OpenAI treats this as more than a collection of small missing browser features. For users who actually adopted Atlas as their daily environment, these details are the product.
