Answer
Hashchats can use extracted page content when it can access the page; chat link previews are a separate convenience. It may not be able to read a signed-in, blocked or unsupported page. Provide the relevant text or file if extraction fails. On updated web, iOS and Android builds, opening or quickly closing an external link does not show a Hashchats link-opening error toast, even when the browser cannot open it. Extracted text does not establish a page's exact visual appearance. Attach a screenshot for a visual question. For Image or Video generation, upload an image reference or paste a supported direct image URL by itself on a blank composer line to import a reference. Audio generation does not fetch linked files as input.
