Stratus

A private memory for your iPhone

Say it once. Ask for it later.

Tell Stratus the things you would otherwise forget: what a friend said they wanted, where you left the spare key, the wine you loved at dinner. Later, just ask. It all stays on your phone.

Free. For iPhone with Apple Intelligence.

Transcribed on this iPhone. Nothing leaves it.

The Stratus Listening sheet transcribing: Sam mentioned he's been wanting a good pour-over coffee set. His birthday is in June, so maybe for that.

How it works

Talk the way you would to a friend who never forgets.

  1. Say it

    Tap Remember, or press the Action Button, and talk. Several things in one breath are fine. You can also type, snap a photo, or share a link from any app.

    "My sister Maya is visiting the 12th through the 15th."

  2. Stratus sorts it

    It works out who and what you mean, links people to your contacts, and turns plans into calendar events and to-dos into reminders when you want it to.

    Maya · sisterEvent · 12th to 15th
  3. Ask later

    Ask in plain words. Stratus answers from what you told it and shows the exact words you said, so you can trust the answer.

    "When is Maya coming?"

Stratus home: up next, change the furnace filter; an event card for Maya's visit; today's memories about Sam.
Everything in one calm listWhat is coming up, then what you said today.
Asking When is Maya coming? Stratus answers Maya is visiting the 12th through the 15th, with the words you said.
Answers with receiptsEvery answer shows what you said and when.
Maya's page: sister, allergic to shellfish, takes oat milk in her coffee, with a timeline of what you said about her.
Everyone, at a glanceWhat is true now about each person, and when you said it.

What it keeps

Everything worth keeping, in one place.

People

Names, relationships and the small details, linked to your contacts with the right spelling.

Plans and to-dos

Events go to Apple or Google Calendar. To-dos go to Reminders or Todoist.

Links and photos

Save from the share sheet with a quick note. Labels, receipts and documents are read for you.

Things and places

Where you put the passports, the paint color in the hallway, the size your kid wears now.

Locked memories

Lock anything sensitive. It opens only with Face ID.

Yours to take

Export everything at any time in an open format.

Private by design

Your memories never leave your devices.

There is no Stratus account and no Stratus server. We could not read your memories if we wanted to.

Questions

Good to know.

How much does it cost?

Stratus is free while we build it out. Anything you save now stays yours, whatever happens to pricing later.

Which iPhones does it work on?

Stratus needs iOS 26 and an iPhone that supports Apple Intelligence, such as iPhone 15 Pro or later, because it understands your memories on the device.

Does it need the internet?

No. Saving and asking work offline. The internet is only used for iCloud sync, link previews, and the services you connect.

Can it forget something?

Yes. Delete any memory with a swipe. Deleted memories wait 30 days in Recently Deleted, then they are gone for good.

Can I get my data out?

Yes. Export everything from Settings at any time.
