How to use live text on ipad

The Live Text feature is limited to relatively recent models of iPad. Here is a direct link to the relevant page of the Guide:

Use Live Text with your iPad camera - Apple Support

As you’ll note, these are the iPad models that support Live Text, Visual Look Up, and lifting a subject from the background:

• iPad mini (5th generation and later)
• iPad (9th generation and later)
• iPad Air (3rd generation and later)
• iPad Pro 11-inch (all generations)
• iPad Pro 12.9-inch (3rd generation and later)

The iPad User Guide is a rich source of frequently overlooked information about your iPad and iPadOS. The Guide is available both online using a web browser (such as Safari), or as an Apple Books download:

The Tips App, installed by default on most models of iPad, provides a brief introduction - and leads you to the User Guide. In case you missed it, here is a link to the Tips App:

Apple also has a huge YouTube Channel - containing videos and feature guidance:

Sorry to say that a 5th gen iPad is not supported for the Live Text feature.

Here is a link to the "Use Live Text With Your iPad Camera" portion of the iPad User Guide.

Click the link at the top of that page "Supported Models" to see that only 9th gen iPad and later, or 5th gen iPad Mini and later are capable.
