How do I remove the Summarise option in iOS 27 Mail app

If you mean the Summarize button that appears when you open an email, I don’t see a separate setting in iOS 27 to remove that button.

Apple only provides a switch for the automatic summaries shown in the message list: Settings > Apps > Mail > Summarize Message Previews. → iPhone User Guide - Apple Support

If that setting isn’t present because Apple Intelligence isn’t available or enabled on your iPhone, there doesn’t appear to be another Mail setting that hides the Summarize control itself.

It is correct that the button to Summarize cannot be removed. Wanting to have a setting to remove the button is certainly a Feature Request that can be sent to Apple.

Feedback - iPhone - Apple

This is a Community Support site where the question was asked on how to remove the Summarize button and the correct answer was given. I have no problem with anyone wanting to have a setting to remove it, but it is not there.

I am not here for points and if I just replied I want to have it too, that is not really providing the answer to the question, is it?

I have the exact problem with emails as the person you responded to. I turned off all AI and still see the "Summary Icon" below the subject line in email list. The icon is a curved arrow with two short lines within the curve. If I turned every possible AI item off for this - why is it still showing? We had great IOS before this current version. WHY does there need to be fiddling???

What every possible AI option did you turn off on iOS 27? There is no switch to turn off Apple Intelligence, all you can do is turn off the automatic preview of the emails and I assume that is what you did. Your emails should no longer be summarized and if you want to manually summarize an email, then you would tap that button. If you never want to summarize an email, then don't tap that button. You cannot remove the button, but you don't have to use it either. Similarly, you may never want to use a particular emoji, it will still be shown in the UI, but you don't have to use it. No fiddling is needed at all.

Well, according to another AI, if Apple Intelligence is not enabled (either because your device doesn’t support it, or you turned it off in your system settings), the Mail app behaves entirely like traditional email clients:

• No On-Demand Summarizing: The Summarize button at the top of long emails or threads will not be available.

I guess it is a bug then.

Your response is coming from a techie that has huge knowledge of knowing your way around Apple devices at Level 10... However, you're not seeing it from my perspective as a daily Apple device user on Level 1, 22 points. I went into Sys Svces and turned off any and all AI toggles. It was labor-intensive. Then you responded.

Yesterday, I received an email from the Apple Support Community, saying that I had 5 "helpfuls" and was seen by 287 other people - and that Wonderful News - tells me others are looking for help as well and tired of fiddling their way to find answers.

I have trouble believing that offering the Summarize button at all does not have AI running in the background. I suspect tapping that button returns the summary it already has done behind the scenes.

Well, it is a good thing that we are not in the business of speculating then.

• You are relying on another AI to tell you that it is a bug?
• Where did this AI model tell you to turn off Apple Intelligence in Settings on iOS 27?
• What happens when you tap the Summarize button?
• Are you only talking about the Setting to automatically summarize emails and turning that off?
