ChatGPT Browser Annotations Gain Custom Controls

This is a meaningful shift from passive page context toward website-aware collaboration, though its desktop-browser and workspace limits currently narrow adoption.

• –Developers can customize selection targets for cards, text, canvas objects, and other UI elements.
• –Metadata gives ChatGPT structured context—such as IDs, properties, or contact details—without relying solely on visible page text.
• –Custom controls support previews for design tokens, writing tone, spacing, colors, and similar application-specific choices.
• –The API captures intent and feedback; sites still need WebMCP or their own tools to perform durable actions.
• –Privacy requires care because attached metadata is shared with both the user and ChatGPT; Enterprise and Edu workspaces are not currently supported. [Browser guidance](https://help.openai.com/en/articles/20001277-using-the-built-in-browser-in-the-chatgpt-desktop-app)
