How to Use Auto-Categorize in Apple Intelligence

Apple Intelligence in Reminders auto-categorizes new tasks into sections like Groceries, Errands, and Work using on-device classification on iPhone 15 Pro and later. It works decently for grocery items, weakly for everything else, and the toggle to turn it off is buried two screens deep. This guide gets you to either flavor in under five minutes.

Last week I added "buy milk" and Apple Intelligence sorted it under "Dairy" inside my Groceries list. Then I added "remind me to think about the Q3 plan" and it sorted it under "Other". Useful for one, useless for the other. That's the honest summary. Let's set it up so it helps you and turn it off where it doesn't.

What you'll achieve

A working Apple Intelligence auto-categorize setup that sorts grocery items into food sections automatically, sorts general reminders into broad buckets when it can, and stays out of the way when you'd rather just type. You'll know how to turn it on, off, and per-list.

What you'll need

  • iPhone 15 Pro, 15 Pro Max, or any iPhone 16 or 17 model
  • iPad with M1 or later (M1, M2, M3, M4)
  • Mac with M1 or later
  • iOS 18 or later (this works in iOS 26.1 with refinements)
  • Apple Intelligence enabled in Settings > Apple Intelligence & Siri > Apple Intelligence > On
  • A region/language Apple Intelligence supports (most English locales, several other languages added through 2025-2026)

If your device isn't on the list, auto-categorize doesn't run on your hardware. Older iPhones get a server-free experience, which means no auto-categorize at all. There is no workaround. Apple Intelligence requires the on-device neural engine in the M1+ / A17 Pro+ class chips.

Step 1: Confirm Apple Intelligence is enabled

Open Settings on your iPhone or Mac. On iPhone, go to Settings > Apple Intelligence & Siri. On Mac, System Settings > Apple Intelligence & Siri.

Check that the master toggle "Apple Intelligence" is on. If it's still downloading models (you'll see a progress indicator), wait. Initial download is usually under an hour on Wi-Fi.

If the option doesn't exist on your device, your hardware is older than M1/A17 Pro. Auto-categorize will not work.

Step 2: Enable auto-categorize for Groceries

Open the Reminders app. Open any list. Tap the three-dot menu at top right. Look for "Show as Grocery List" or "Smart List Categorization" depending on iOS version.

When you toggle a list to Grocery type, Apple Intelligence sorts new items into food categories: Produce, Dairy, Bakery, Frozen, Pantry, Beverages, Household, Other. As of May 2026 the categorization is genuinely good for common items. "Almond milk" goes to Dairy. "Toilet paper" goes to Household. "Bell pepper" goes to Produce.

This is the auto-categorize feature most people actually want.

Step 3: Use auto-categorize on a general list

Newer iOS versions (iOS 18+, refined in iOS 26) extend auto-categorize beyond grocery. On a regular list, Apple Intelligence may suggest sections like "Today", "Errands", "Work", "Personal".

To enable on a non-grocery list: open list settings, look for "Auto-Categorize" toggle. Available on iPhone 15 Pro and newer with Apple Intelligence enabled.

Honestly, the non-grocery categorization is hit-or-miss. "Email Sundeep about Q4 numbers" sometimes goes to Work, sometimes goes to Other. The model is conservative. If it's not sure, it picks Other. Which means a lot of stuff ends up in Other.

Step 4: Test it with a known input

Add 8-10 items to a Grocery list. Use a mix:

  • "milk"
  • "bananas"
  • "Tide detergent"
  • "ground beef"
  • "frozen peas"
  • "bread"
  • "Coke Zero"
  • "ginger"

Watch where they land. Within 1-3 seconds of typing, Apple Intelligence drops each into a section. If anything sits in Uncategorized for 30+ seconds, the model is either still loading or the item name is too unusual.

Re-edit any wrong placements. The model learns from your corrections, slowly. It will take 20-40 corrections before you notice the personalization.

Step 5: Turn off auto-categorize on a single list

If a list is being mis-categorized too often, turn off auto-categorize for that one list without affecting the rest.

Open the list. Three-dot menu. List Info. Uncheck "Auto-Categorize" or set "List Type" back to Standard.

The list reverts to a flat order, top to bottom, in whatever order you typed.

Step 6: Turn off auto-categorize globally

If you want to kill it everywhere, two options.

Option A: Disable Apple Intelligence entirely. Settings > Apple Intelligence & Siri > Apple Intelligence > Off. This nukes auto-categorize plus every other Apple Intelligence feature (writing tools, image cleanup, notification summaries, Genmoji). Heavy hand.

Option B: Per-feature disable. As of iOS 26.1 you can disable specific Apple Intelligence features individually. Settings > Apple Intelligence & Siri > scroll down to Features > toggle off "Reminders Categorization". Keeps everything else.

Most people who get frustrated should pick Option B. The grocery categorization is genuinely useful even if the general categorization isn't.

Common pitfalls

  • Auto-categorize doesn't fire on older lists. Apple Intelligence categorizes new items as you add them. Existing items in a list don't get retroactively sorted. To re-sort an old list, you'd have to delete and re-add items or move the list to a new one.
  • Categorization seems random for first day. The model is loading. Give it a day. After 24-48 hours of normal use, results stabilize.
  • It re-categorizes wrong every time you fix it. Apple Intelligence personalization is slow. It takes 20+ corrections of the same type before patterns shift. If "yogurt" keeps going to Other instead of Dairy, fix it 25 times. Or move on with your life.
  • Items with multiple plausible categories. "Chicken broth" can be Pantry or Frozen depending on what you buy. Apple picks one based on training data. If you always buy frozen, you'll be correcting it forever. Use a more specific name like "frozen chicken broth".
  • Mixed-language input. As of May 2026, English-only auto-categorize is most reliable. Hindi, Hinglish, Spanish, French support exists but is noticeably less accurate.

Verification

You know it's working when:

  1. New grocery items land in food sections within 1-3 seconds
  2. The sections that appear in the list match what you'd expect (Dairy, Produce, etc.)
  3. After 20-30 corrections, your top-10 most-frequent items stay in the right place
  4. Toggling off Auto-Categorize on a list returns it to a flat order immediately

Where it fits in the bigger picture

Apple Intelligence in Reminders is one of three AI features that hit Reminders in iOS 18: auto-categorize, email-to-reminder (capture from Mail), and the Today view tweaks. The auto-categorize piece is the most consistent of the three.

Honestly, Apple Intelligence auto-categorize is fine. It's not the AI superpower the launch keynote suggested. It's a slightly smart sort. The on-device Qwen 3 model in Ultra Reminders does something different: it takes a brain-dump like "okay so tomorrow I need to call Vimal about the lease, also Maya's school form is due Friday, oh and I keep forgetting to book the dentist" and splits it into three distinct reminders with dates, in under a second. That's the AI move that actually changes a workflow. Auto-categorize sorts. Brain-dump capture creates.

FAQ

Q: Does auto-categorize work on iPhone 14 or older?

A: No. Auto-categorize requires Apple Intelligence, which requires A17 Pro (iPhone 15 Pro), A18 (iPhone 16), or M-series silicon. The iPhone 14 and older lack the neural engine performance Apple needs for on-device categorization.

Q: Is the categorization done on my device or on Apple's servers?

A: On-device. Apple Intelligence's reminder categorization runs locally on the neural engine. Your reminder titles do not leave your device for this feature. Some other Apple Intelligence features use Private Cloud Compute, but auto-categorize is fully local.

Q: Can I create my own categories?

A: Not for auto-categorize. You can create your own sections inside any list manually (long-press in the list, "Add Section"), but Apple Intelligence won't auto-place items into your custom sections. The categories the model uses are baked in.

Q: What languages does it work in?

A: English (US, UK, Canada, India, Australia) is best supported. Spanish, French, German, Italian, Portuguese, Japanese, Korean, simplified Chinese added through 2025. Hindi/Hinglish added in 2026 but with lower accuracy. Other languages may not have categorization yet.

Q: Does it learn from my corrections?

A: Slowly. Apple Intelligence's personalization runs on-device and adjusts after a meaningful number of corrections of the same type. Don't expect immediate change after one fix. Expect drift after 20-40 corrections of the same item.
