Suggestions on an iPhone can come from several places, including Siri, Search, Safari, the keyboard, and individual apps. Clearing or disabling one source will not necessarily remove suggestions everywhere.
Reduce Siri and Search suggestions
- Open Settings and go to the Siri or Apple Intelligence & Siri/Search-related settings available on your iOS version.
- Review the suggestion options for Search, the Home Screen, sharing, and other surfaces.
- Turn off the types of suggestions you do not want.
- For an app-specific problem, open that app’s Siri/Search settings and disable its suggestion or learning options.
If you mean Safari suggestions, check Safari’s settings separately. If you mean words appearing above the keyboard, review the keyboard’s predictive-text settings instead.
Before changing everything, identify where the unwanted suggestion appears. That keeps you from disabling useful recommendations in unrelated parts of the phone.
