I’m a regular user. Why am I basically doing compatibility testing for ChatGPT?
I keep running into this when using ChatGPT across Web, Desktop, Mobile, Chat, and Work.
Sometimes a feature exists in one place but not another. That’s understandable — I don’t expect every platform and mode to have perfect feature parity all the time.
What frustrates me is figuring out whether a feature is actually unavailable or whether I just can’t find it.
For example, I recently tried to find Deep Research in different places.
Suddenly I’m checking:
-
Is it available in normal Chat?
-
What about Work?
-
Web?
-
Desktop?
-
Mobile?
-
Is this a plan limitation?
-
A rollout difference?
-
A version difference?
-
Or am I simply looking in the wrong place?
And to answer what should be a very simple question, I may end up checking Help Center articles, release notes, Community posts, or comparing different versions of ChatGPT myself.
Regular users shouldn’t need developer-level product knowledge just to understand where a feature is available.
If a feature isn’t available on a certain platform or in a certain mode, that’s fine. Just tell me.
For example:
Deep Research isn’t currently available here. You can use it in Chat on Web or Mobile.
That’s enough.
I don’t need every platform and mode to be identical.
I just want ChatGPT to clearly tell me:
Does this feature exist here? If not, where can I use it?
Perfect feature parity may not always be possible.
Feature availability should at least be transparent.
