How to Enable or Disable Inline Predictive Text on iPhone in iOS Keyboard Settings

Modern iterations of iOS, beginning with iOS 17 and continuing into iOS 18, incorporate sophisticated machine learning models directly into the system keyboard. One of the most prominent additions is inline predictive text, an intelligent typing feature that predicts the next few words or the remainder of your sentence as you type. Unlike the classic predictive text bar that displays three suggested word chips above the keyboard, inline predictions appear as faint grey text directly ahead of your blinking cursor, completing entire phrases whenever you tap the Space bar.

While inline text suggestions can dramatically accelerate typing speed for common colloquial phrases and routine email replies, many users find the grey text visually distracting. If you frequently type multilingual sentences, draft technical jargon, or compose nuanced prose, inline completions can cause inadvertent insertions if you habitually press the Space bar after completing a thought. Fortunately, iOS provides a dedicated toggle to turn inline completions off without sacrificing traditional word suggestions or autocorrect. This guide explains how to enable or disable inline predictive text on iPhone, adjust keyboard learning profiles, and troubleshoot prediction discrepancies.

How Inline Predictions Differ from the Classic Predictive Bar

Understanding the dual-tiered structure of iOS typing assistance helps ensure you disable only the features causing friction:

• Inline Predictive Text (Grey Ghost Text): Uses on-device transformer language models to predict entire phrases or sentence conclusions. The predicted text appears directly within your active text field in a light grey shade. Pressing the Space bar instantly accepts and inserts the entire ghosted phrase.
• The Classic Predictive Bar (Above Keyboard): A dedicated horizontal strip situated above the top row of keyboard keys that presents three individual candidate words based on probability and context. You must tap a specific candidate box with your finger to insert it.
• Autocorrect: Automatically corrects misspelled words, transposes accidental keystrokes, and inserts apostrophes when you tap Space, regardless of predictive suggestions.

Disabling Inline Predictive Text in iOS Keyboard Settings

If you want to keep the classic three-word predictive bar above the keyboard while eliminating the distracting grey inline suggestions inside your sentences, follow these steps:

1. Open the Settings app on your iPhone running iOS 17, 18, or newer.
2. Scroll down and tap General.
3. Select Keyboard.
4. Scroll to the All Keyboards section.
5. Locate the toggle labelled Show Predictions Inline.
6. Switch the toggle to the Off position.

Immediately upon toggling this option off, the grey ghost text will cease to appear ahead of your cursor in Messages, Mail, Notes, Safari, and third-party messaging apps. The traditional predictive bar above your keyboard keys remains fully functional, allowing you to manually choose suggested words at your own pace without accidental Space bar auto-completions.

Enabling Inline Predictive Text on Compatible iPhones

If you previously switched the feature off or if inline completions are not appearing on your device, verify that your hardware and language configurations meet Apple’s prerequisites:

1. Navigate to Settings > General > Keyboard.
2. Ensure the primary toggle for Predictive is switched On. (If general Predictive text is disabled, the sub-option for inline predictions cannot function).
3. Toggle on Show Predictions Inline.
4. Check your installed keyboards by tapping Keyboards at the top of the menu. Inline predictions currently require an Apple neural engine running on an iPhone 12, 13, 14, 15, 16, or newer and are supported primarily across English (US, UK, Canada, Australia), French, Spanish, German, and Italian keyboard layouts.

Resetting the Keyboard Dictionary to Clear Learned Predictions

Over time, your iPhone learns your idiosyncratic typing patterns, acronyms, and slang. If inline predictive text frequently suggests inappropriate phrases, typos, or outdated email addresses, you can reset the on-device language cache back to factory condition without affecting your contacts, apps, or media:

1. Launch Settings and tap General.
2. Scroll to the bottom of the screen and select Transfer or Reset iPhone.
3. Tap Reset at the bottom of the display.
4. From the popup menu, tap Reset Keyboard Dictionary.
5. Enter your iPhone passcode when prompted, then confirm by tapping Reset Dictionary.

This action purges all custom words and contextual associations your iPhone has cached, allowing the neural engine to relearn clean typing suggestions from scratch.

Troubleshooting Missing Inline Predictions

If inline predictions fail to generate even after being enabled in Settings, check the following environmental factors:

• Low Power Mode Restrictions: When your battery is low and Low Power Mode is active, iOS throttles background neural engine operations to conserve battery life, which can cause inline predictions to appear erratically or pause entirely.
• Third-Party Keyboards: Third-party keyboard extensions (such as Gboard or SwiftKey) utilise their own proprietary prediction algorithms. Apple’s native inline predictive text is exclusive to the stock iOS keyboard.
• Dictation and Language Conflicts: Ensure your primary keyboard matches your active typing language. If you have multiple languages installed, tap the globe icon on your keyboard to verify the active language profile.
