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, and above all of them sits a master switch in Settings > Apple Intelligence & Siri.

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.

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.

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 is released tomorrow, 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. We do not yet know how the update treats a phone that had summaries switched off, because it has not shipped.

Two documented cases of the setting coming back by itself, and one update landing tomorrow.

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. 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.

Summaries are not on that list.

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 its own guide page sits this footnote: “Apple Intelligence uses generative models, and results may vary. Verify important information for accuracy.”

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.

What to do with this

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) if you want none of it. You will lose the writing and photo tools too.
  5. Write “check Summarize Notifications” on the note where you keep your update habits. Do it after every iOS update, starting with the one arriving tomorrow.

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.

If you want to go deeper

  • “Can I turn off only the apps I care about?” Yes. In Settings > Notifications > Summarize Notifications, leave the main switch on and tap Choose Notifications to Summarize to pick app by app. Or swipe left on any summarized notification, tap Options, and turn it off for that app.
  • “What else on this phone is doing something similar?” Quite a lot. We counted twelve places AI now appears on a typical phone in how do I get rid of AI on my phone, including which ones have a real off switch and which only have a hide button.
  • “Is any of this going to cost me money?” Apple Intelligence itself is bundled, but two features on Apple’s own page already require a paid subscription. We went through the gates in do I have to pay for Apple Intelligence.
  • “My phone is also screening my calls now.” Different feature, different menu — see how to turn off call screening on iPhone.
  • “What about Android?” The equivalent assistant is covered in what is Gemini on my Android phone.

Questions people actually ask about iPhone summaries

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, and there is a master switch under Settings > Apple Intelligence & Siri that removes everything at once.

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, and Apple notes the on-device models are removed from your device when you do it.

Are Apple Intelligence summaries accurate?

Not reliably, and Apple says so on its own guide page: “Apple Intelligence uses generative models, and results may vary. Verify 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. Whether iOS 27, released September 14, 2026, does the same is not yet known. The safe habit is to check Settings > Notifications after every update.

Can Screen Time block AI summaries?

No. Screen Time’s Intelligence & Siri restrictions cover three things: Writing Tools, image generation, and intelligent extensions such as ChatGPT. Summaries are not among them. 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.
