The X app intercepts x.com links on many phones. This page routes the Grok-on-X demo into a real browser window/tab and never relies on the X app. Incognito cannot be forced by a website — use your browser’s private mode if you want it.
Android: primary button uses a Chrome package Intent so the X app is skipped.
iOS / desktop: opens a new browser tab/window. If the app still appears, use Copy → paste into a private browser tab.
