How to Share Your Screen in ChatGPT

ChatGPT can see and respond to visual content from your screen in two main ways: you upload a screenshot or image, or you use the camera feature in Advanced Voice Mode on mobile. There is no button that streams your desktop live to ChatGPT in the same way a video call does, but both methods let it read, analyze and comment on what is on your screen.

The findings from a screen-sharing session — bugs spotted, layout feedback, an error message decoded — live only in the chat when the conversation ends. Tools like fenbs give those findings a persistent home in a project record that the next assistant reads at the start of the next session.

Uploading a screenshot on desktop

Take a screenshot of whatever you want ChatGPT to look at. On Windows, use Snipping Tool or Win + Shift + S. On a Mac, use Cmd + Shift + 4. Save the image and then drag it into the ChatGPT message input, or click the paperclip icon and select the file.

ChatGPT can read text in the image, describe what it sees, spot errors in interface designs or code editors, and answer questions about the content. Ask your question in the same message as the upload for the clearest response.

You can upload multiple screenshots in a single message if you want ChatGPT to compare two states — for example, a before and after when debugging a visual change.

Using the camera view in mobile Advanced Voice Mode

In the ChatGPT mobile app, start a voice conversation and look for the camera icon. Switching it on lets ChatGPT see what your phone camera is pointing at and describe or comment on it in real time. This is useful when you want to show something physical — a printed document, a whiteboard or a product — rather than taking a separate screenshot.

The camera feed is processed by ChatGPT while the voice session is active. Nothing from the session is automatically saved to a separate record. When the conversation ends, what ChatGPT said about what it saw is in the chat history, the same as any other message.

What to keep off screen before you share

Before uploading a screenshot or pointing a camera at your screen, consider what else is visible. Notifications, email previews, browser tabs and open documents can appear in a wider crop than intended. Close or cover anything you do not want to include.

For screenshots that include customer data, financial figures or confidential documents, check what your organization's policy is on uploading business content to external AI services. When in doubt, blur or crop the sensitive parts before uploading. Some image editors and screen capture tools include redaction features that can black out specific regions before you share.

OpenAI's data handling practices for uploaded images are described on the OpenAI help center. For questions about whether a shared conversation link exposes uploaded images to others, see how to share a ChatGPT chat.

Getting useful responses from visual input

ChatGPT responds better to visual input when you frame the question clearly. Instead of "what do you think?", try "what error is shown in this stack trace?" or "why does this layout look unbalanced?". The more specific the question, the more targeted the answer.

For complex work — a bug that requires several screenshots to explain, or a design review with multiple states — break the session into steps. Upload one context screenshot first, confirm ChatGPT has read it correctly, then proceed. This avoids asking it to hold too many visual details in one prompt.

What happens after the session ends

The insights from a screen session live in the conversation. The next time you open ChatGPT, they are in that chat's history. But a new chat starts from zero — it has no knowledge of what you showed in a previous session unless you upload the screenshots again or paste the relevant conclusions.

If you found something worth acting on — a confirmed bug, an approved design direction, an outstanding question — writing it down in a project record gives it a form the next assistant can read without re-running the screen session.

How to do this with fenbs

1. Create a free account and set up a board for the project you are reviewing in the screen session.
2. After ChatGPT identifies an issue or an answer, add it to the board as a task with the finding in the description.
3. Write any confirmed directions or constraints as Decisions and rules so the next session starts with those facts already established.
4. Connect your AI app at Integrations so the next assistant reads the project context, including the tasks from the screen review, before it starts.
5. Keep the session moving: share another screenshot for the next question rather than asking ChatGPT to remember what it saw in an earlier upload.
