How to Turn Off AI Summaries on iPhone: Four Switches, Not One

ByProf. H

There is no single switch. Apple put AI summaries in four separate menus, and turning one off does nothing to the other three. The one most people want is Settings > Notifications > Summarize Notifications. That stops the rewritten alerts on your lock screen. Mail and Messages each have their own switch somewhere else. On iOS 26 and earlier, a master switch sits above all of them in Settings > Apple Intelligence & Siri; on iOS 27, released September 14, 2026, Apple’s own guide no longer lists a single switch.

Last verified: October 3, 2026. We re-read every Apple page cited here against the iOS 27 guide today. The three summary switches did not move: same names, same menus. Three things did change, and each is corrected below: Apple’s “turn off” page no longer lists a master switch, Screen Time’s AI controls now sit under a menu called Siri, and the warning footnote is worded differently.

What we checked on September 13, 2026

We took the nine pages Google returned for this exact question, fetched each one, and searched it for the three summary settings by their real names.

  • 8 of 9 pages could be fetched. One blocked us.
  • 0 of those 8 named all three switches.
  • 1 of 8 named two of them — and that one was Apple’s own help page, which is not trying to answer this question at all.

So if you turned something off and the summaries kept coming, you are not doing it wrong. You were almost certainly given one switch out of four.

Why one switch was never going to be enough

An AI summary is your iPhone rewriting somebody else’s words into a shorter version before you read them. Your daughter sends four texts about Sunday dinner; the lock screen shows you one line that the phone wrote.

Apple did not build that as one feature. It built it as several, in different apps, each with its own setting. So “turn off AI summaries” is not one action. It is up to four.

Here is every one of them. Each path below comes from Apple’s own iPhone User Guide, which we opened and read on September 13, 2026, and re-read against iOS 27 on October 3, 2026.

Chart of the four separate iPhone settings that control AI summaries, with the exact menu path for each.
Four menus, four switches. Number 1 is the one most people are looking for.

Switch 1: the lock screen alerts (this is the one you want)

This is the big one. It controls the rewritten notifications — the stacked texts, the group chat, the news alert that came out strange.

  1. Open Settings.
  2. Tap Notifications.
  3. Tap Summarize Notifications.
  4. Turn Summarize Notifications off.

That is Apple’s own wording, from its support page on notification summaries. From that moment, every notification arrives in the sending app’s original words.

You can also do it one app at a time, from the lock screen

If a summary annoys you the moment it appears, you do not have to go hunting through Settings. Swipe the notification partway to the left, tap Options, then tap Turn off Summaries. Apple added that shortcut in iOS 18.3. It switches off summaries for that one app and leaves the rest alone — useful if you like the summary for shopping alerts but not for your family group chat.

Switches 2 and 3: Mail and Messages have their own

These two surprise people, because the notification switch does not touch them. Open the Mail app itself and the summary is still sitting on top of each email.

Mail. Go to Settings > Apps > Mail, then turn Summarize Message Previews off. Apple’s guide explains what you get back: instead of a summary, you see “the first lines of the most recent message.”

Messages. Go to Settings > Apps > Messages, then turn Summarize Messages off.

Notice that both live under Apps, not under Notifications. That is why people who correctly turn off notification summaries still see summaries inside the apps and conclude the setting did not work.

What about Safari? Nothing to turn off

Safari can summarize a web page, but only when you ask it to — you tap Summarize in Reader, or tap the sparkle in the address bar. It does not rewrite pages on its own the way notifications get rewritten.

So there is no Safari switch in the list above, and you do not need one. If you never tap it, it never runs.

Switch 4: the master switch, and what it costs you

If you want all of it gone, go to Settings > Apple Intelligence & Siri and turn Apple Intelligence off. That is the path on iOS 26 and earlier.

On iOS 27 this may not be there. Apple’s iOS 27 page on turning off Apple Intelligence, read October 3, 2026, no longer offers one switch. It lists features one by one instead: the three summary switches, Prioritize Notifications, Siri AI, and a handful of smaller ones. iThinkDifferent reported on release day that iOS 27 removed the master toggle. We have not checked this on an iPhone ourselves, so treat it as Apple’s documentation plus one report. Either way, the three switches above still work.

Be clear about what that does. Apple’s support material notes that when you turn Apple Intelligence off, the on-device models are removed from the device. You lose the summaries, and you also lose the writing tools, the cleanup tool in Photos, Genmoji, and the rest. If your only complaint is the lock screen, switch 1 is the smaller, better tool.

Most of the confusion in this topic comes from one thing: the phone does not tell you which words on this screen are the sender’s and which are its own. Apple marks summaries with a small icon and italic text, which is easy to miss at arm’s length. Photo: Kristin Hardwick, StockSnap — CC0.

The part that is missing from almost every guide: it does not stay off

This is the thing worth knowing more than any menu path, and it is why we wrote this today rather than next week.

Apple has switched Apple Intelligence back on during system updates, and it is documented in more than one release.

In January 2025, Apple’s own iOS 18.3 release notes said the feature “will be enabled automatically during iPhone onboarding” for people upgrading. Two months later, after iOS 18.3.2, MacRumors reported that readers found Apple Intelligence “automatically turned on, regardless of whether it was turned off prior to the update being installed.” Users were shown a splash screen whose only button was Continue.

iOS 27 was released on September 14, 2026. Apple says it carries the new Siri AI, which can search across your apps, read old email for a confirmation number, and answer questions about what is on your screen. As of October 3, we have not found a documented report, from Apple or a major Apple news site, that iOS 27 switched summaries back on for people who had turned them off. Some forum users have complained, but we could not verify those posts. An absence of reports is not a guarantee, so the habit below still stands.

Two documented cases of the setting coming back by itself. iOS 27 shipped September 14; no documented case for it as of October 3, 2026.

So add ten seconds to your routine. After any iOS update, open Settings > Notifications and look at Summarize Notifications again. If the update turned it back on, you will see it immediately. If it did not, you have lost ten seconds.

One step deeper: Screen Time will not do this for you

A common suggestion is to lock AI down through Screen Time restrictions. It is a reasonable idea and it does not work for summaries.

We read Apple’s Screen Time page for Apple Intelligence on September 13, 2026. On iOS 26, under Content & Privacy Restrictions > Intelligence & Siri, Apple lists exactly three things you can block: Writing Tools, image generation (Image Playground, Genmoji, Image Wand), and intelligent extensions, meaning outside AI such as ChatGPT.

On iOS 27 the menu was rebuilt. Apple’s guide, re-read October 3, 2026, puts it under Content & Privacy Restrictions > Siri: block Siri, allow only Siri (Classic Version), or allow Siri AI (Beta) with capabilities such as Image Creation, Sensitive Topics and Explicit Language set to Allow or Block.

Summaries are not on either list.

The iOS 26 menu. On iOS 27 the list changed, and summaries are still not on it. Worth knowing before you spend twenty minutes in the wrong menu.

Why Apple itself put a warning on this feature

If you have wondered whether it is unreasonable to distrust a summary, it is not. Apple distrusts them too, in writing.

At the bottom of the iOS 26 version of its own guide page sits this footnote, as it read on October 3, 2026: “Apple Intelligence uses generative models and outputs may vary. Check important information for accuracy.” (The iOS 27 version of the page carries a usage-limits note instead.)

There is history behind that sentence. In December 2024 the BBC complained to Apple after a notification summary misrepresented one of its headlines. In January 2025, with iOS 18.3, Apple temporarily disabled notification summaries for apps in the News & Entertainment category, made the beta warning in Settings more explicit about possible errors, and started showing summarized text in italics so it is visually separate from the app’s own words.

That is a company shipping a feature and then adding guardrails to it in public. It is a good reason to treat a summary as a hint about what arrived, never as the message itself — which matters most when the message concerns money, health or a deadline. The same caution applies to medical documents you might paste into a chatbot.

Switch off notification summaries first; that fixes the lock screen

Five minutes, in this order.

  1. Settings > Notifications > Summarize Notifications > off. This is the one that fixes the lock screen. Do it first and stop here if that is all you wanted.
  2. Settings > Apps > Mail > Summarize Message Previews > off. Your email list goes back to showing the first lines of each message.
  3. Settings > Apps > Messages > Summarize Messages > off.
  4. Decide about the master switch. Only turn off Apple Intelligence entirely (Settings > Apple Intelligence & Siri, on iOS 26 and earlier) if you want none of it. You will lose the writing and photo tools too. On iOS 27, Apple’s guide lists no single switch, so steps 1 to 3 are the whole job.
  5. Write “check Summarize Notifications” on the note where you keep your update habits. Do it after every iOS update, including the small ones that follow iOS 27.

If you do not see these settings at all, that is normal and not a fault. Apple Intelligence runs on iPhone 15 Pro, iPhone 15 Pro Max and iPhone 16 or later, on a supported language. On an older iPhone there is nothing to switch off, because nothing is summarizing anything.

Keep summaries on, but choose which apps get them

Mail, Messages and whether an iOS update turns summaries back on

How do I turn off AI summaries on iPhone?

Go to Settings > Notifications > Summarize Notifications and turn it off. That handles the rewritten alerts on your lock screen, which is what most people mean. Mail and Messages have separate switches under Settings > Apps. On iOS 26 and earlier, a master switch under Settings > Apple Intelligence & Siri removes everything at once; Apple’s iOS 27 guide no longer lists one.

How do I turn off AI summary on iPhone Mail?

Go to Settings > Apps > Mail and turn off Summarize Message Previews. Your inbox then shows the first lines of each message again instead of a written summary. Turning off notification summaries does not do this — they are two different settings.

How do I turn off AI summaries on iPhone Messages?

Go to Settings > Apps > Messages and turn off Summarize Messages. This is separate from the notification summary for the Messages app, which lives under Settings > Notifications. If summaries persist after you change one, change the other.

Why does my iPhone summarize my notifications?

Because Apple Intelligence is on, and summaries come with it. Apple describes the goal as condensing long or stacked notifications so they are easier to take in at a glance. It is on by default on supported iPhones, and turning it off is a setting change, not a repair.

Does turning off summaries turn off Apple Intelligence?

No. Turning off Summarize Notifications stops the rewritten alerts and leaves everything else running. Turning off Apple Intelligence in Settings > Apple Intelligence & Siri is the larger step on iOS 26 and earlier, and Apple notes the on-device models are removed from your device when you do it. On iOS 27, Apple’s guide lists the features one by one instead of one switch.

Are Apple Intelligence summaries accurate?

Not reliably, and Apple says so on its own iOS 26 guide page: “Apple Intelligence uses generative models and outputs may vary. Check important information for accuracy.” In January 2025, after a BBC complaint about a misrepresented headline, Apple temporarily disabled summaries for News & Entertainment apps in iOS 18.3 and began showing summarized text in italics to separate it from the original.

Will an iOS update turn summaries back on?

It has happened. Apple’s iOS 18.3 release notes stated Apple Intelligence would be enabled automatically during onboarding for upgraders, and after iOS 18.3.2 MacRumors reported users finding it switched on regardless of their previous setting. For iOS 27, released September 14, 2026, we found no documented case as of October 3, 2026, which is not a guarantee. The safe habit is to check Settings > Notifications after every update.

Can Screen Time block AI summaries?

No. On iOS 26, Screen Time’s Intelligence & Siri restrictions cover three things: Writing Tools, image generation, and intelligent extensions such as ChatGPT. On iOS 27 the controls moved under Content & Privacy Restrictions > Siri. Summaries are on neither list. Use the Notifications, Mail and Messages switches instead.

I do not see these settings on my iPhone. What is wrong?

Probably nothing. Apple Intelligence requires iPhone 15 Pro, iPhone 15 Pro Max, or iPhone 16 and later, with the device set to a supported language. On an older iPhone the settings do not appear because the feature is not running, so there is nothing to turn off.
