Make AI text larger on your phone

Before you start

Open a short answer in the AI app you normally use. Keep it available for a before-and-after comparison. These are operating-system settings, not features supplied by the AI app.

On iPhone

1. Open Settings.
2. Open Accessibility.
3. Open Display & Text Size.
4. Inspect the text and contrast options available for your iOS version.
5. Adjust one option.
6. Return to your AI app and compare the same answer.

On Android

1. Open Settings.
2. Search for Font size.
3. Move the slider one step towards larger text.
4. Return to your AI app and check the answer.
5. If controls are still small, search Settings for Display size.
6. Adjust it and check the input field and send button again.

Check more than a paragraph

Read one answer, open the chat list and write a new message. Check whether buttons remain visible and lines fit the screen. If you must scroll sideways to follow ordinary text, reduce the setting slightly or try the browser version.

If nothing changes

Reopen the app. If it ignores text size, compare its browser version with browser zoom. Restore the original size if the larger setting hides a control you need.

Availability and limits

Menu names vary by iOS version, Android version and manufacturer. Android’s font setting does not affect every app. The linked Apple guide follows the selected iOS version; use its version selector if your menus differ.
