One of the most useful features hidden inside the ChatGPT desktop app is also one that many users may have never tried: Appshots.
The feature solves a simple problem. Instead of spending time explaining what you are looking at on your computer, you can simply send the current app window to ChatGPT and let it use that context to help you.
OpenAI describes Appshots as a way to provide ChatGPT with context from applications on Windows and macOS. An Appshot captures the application window currently in the foreground and sends it to a ChatGPT conversation.
One of the most underrated features in the ChatGPT desktop app: Appshots.
Appshots take the context on your screen and bring it into the desktop app, allowing you to share instead of describe.
You’ll be surprised at how useful it is.

What are ChatGPT Appshots?
Think of Appshots as a quick bridge between whatever you are doing on your computer and ChatGPT.
For example, imagine you are looking at an error message, a complicated settings page, an email, a design, or an API reference. Normally, you would have to take a screenshot manually, upload it, and then explain what you want ChatGPT to look at.
With Appshots, you can share the active application window directly.
OpenAI says an Appshot can include an image of the visible window as well as text that the application makes available to ChatGPT. Once added to a conversation, it behaves like an attachment.
That makes the feature particularly useful when showing something is easier than describing it.
How to take an Appshot
Getting started is surprisingly simple.
First, bring the application window you want ChatGPT to see to the foreground.
Then use the keyboard shortcut:
- macOS: Press both Command keys
- Windows: Press both Alt keys
You can also configure a custom keyboard shortcut for Appshots in ChatGPT’s settings.
After capturing the Appshot, you can ask ChatGPT to work with the information on screen.
Depending on your settings, Appshots can be added to a new conversation or an existing recent conversation. OpenAI’s documentation says that if you interacted with a chat within the previous 60 seconds, an Appshot can be added to that recent conversation automatically.
Why Appshots can be surprisingly useful
The biggest advantage is that you don’t have to translate visual context into words.
Suppose a program suddenly displays an error. Rather than typing out the entire message, you can share the window and ask:
“What does this error mean, and how can I fix it?”
The same approach can work with a complicated settings screen:
“Which option should I change to enable this feature?”
Or with an API reference:
“Look at this documentation and write an example using this API.”
OpenAI specifically highlights use cases including sharing API documentation, emails and calendar views, image-editing or design applications, and errors or settings that are easier to show than explain.
It is more than just a screenshot
One important detail is that Appshots aren’t necessarily limited to the pixels you can see.
OpenAI says Appshots can include the visible image of the foreground window along with text available from that window, including text that an application makes accessible outside the currently visible scrolling area.
That gives ChatGPT additional context compared with simply describing what is on screen.
However, the exact information available can depend on the application. OpenAI notes that some apps and websites may provide only the visible screenshot rather than content outside the current view.
Privacy and permissions are important
Because Appshots can capture what is displayed in another application, users should check the information visible on screen before sharing it.
On macOS, ChatGPT may require Screen & System Audio Recording permission to capture the window and Accessibility permission to read available text from it.
OpenAI also recommends avoiding Appshots containing sensitive information unless that information is necessary for the task.
That’s particularly worth remembering when capturing email, financial information, private conversations, work documents, or other confidential material.
A small feature with a big convenience factor
Appshots may not be the flashiest ChatGPT feature, but they address one of the most frustrating parts of using an AI assistant: giving it enough context to understand what you’re talking about.
Instead of writing a long explanation, taking a separate screenshot, cropping it and uploading the image, you can bring the relevant application to the foreground and use the Appshot shortcut.
For people who regularly use ChatGPT alongside other desktop applications, it’s one of those features that can quickly become part of the everyday workflow.
And if you’ve never tried it, the shortcut is easy to remember: both Command keys on Mac, or both Alt keys on Windows.
Just make sure you review what is visible before sending the capture.
