How it works

How does Sive work?

  1. Say it however it comes out

    Type or dictate everything at once: appointments, errands, things not to forget. No forms, no fields, no order.

  2. Check the cards

    Sive proposes each item with its date and time. Approve it, untick what you don’t want, or ask for a change in plain words.

  3. It’s in your planner

    Events land on your calendar, reminders notify you when they’re due, and to-dos wait in your list.

One chat for everything

Plan, change and ask in plain words

The same box you dump into also moves things, cancels things, ticks things off and answers questions about your week.

Capture a whole day in one message

Several things in one breath become separate items, each with the right date, time and type.

Your planner

Everything in its place, at a glance

What you approve lands in a calm planner with three views: today, your calendar and your lists.

Home tells you what’s next

Open Sive and see what’s overdue, what’s coming up next with a countdown, the rest of today, and your to-dos. A glance, no digging.

  • The next thing on your day, front and centre
  • Overdue reminders pulled to the top
Sive Home screen: an overdue reminder, the event happening now, the rest of today and to-do lists.

A calendar that knows the difference

Timed events, all-day events and reminders each look like what they are. An event’s advance reminder rides along on its block instead of cluttering the day.

  • “Remind me 30 minutes before” just works
  • Move an event and its reminder follows

Lists that sort themselves

“Buy eggs, bread and coffee” becomes one grocery list with three items. Group to-dos into categories and drag them between groups.

  • Spoken or typed lists become real lists
  • Ticked items clear themselves after a day

Features

What can Sive do?

Dictation that works

Speak naturally. Sive adds the commas and full stops and turns spoken lists into real lists.

You approve everything

Every item is a card you approve, revise or reject. AI can make mistakes; nothing is saved behind your back.

Reminders before events

Ask for a heads-up an hour before, and it stays linked to the event even if you move it.

A morning recap

One notification with what today holds, at the hour you choose. Quiet on days with nothing on.

Private iCloud backup

Your plan is stored on your iPhone and backed up to your own iCloud, so it follows you to a new phone or when reinstalling the app.

Works offline

The full assistant uses the internet. With no connection, iPhones with Apple Intelligence switch to an offline assistant, and your calendar, lists, Home and editing by hand never need a connection.

Privacy

What happens to what you write?

The full detail is in the privacy policy.

  • Your plan stays yours. Events, reminders and to-dos live on your iPhone and in your own private iCloud. We never receive them.
  • The chat uses a cloud AI model. The message you send the assistant is passed to an AI model operated by Google to be read.
  • Nothing is kept or trained on. No message or reply is stored on our side, and nothing you send is used to train anyone’s AI model.

FAQ

What is Sive?

Sive is an AI planner for iPhone. You type or dictate everything on your mind in one message, and Sive sorts it into calendar events, reminders and to-dos. Each item appears as a card you approve, revise or reject, and nothing is saved until you approve it.

Which iPhones does Sive work on?

Sive works on any iPhone running iOS 26 or later. Apple Intelligence is not required. Sive is iPhone only and currently in English.

Does Sive need an internet connection?

The chat assistant needs a connection, because it uses a cloud AI model to read what you write. Everything else works offline: the calendar, the to-do list, the home screen, and adding or editing items by hand. On iPhones with Apple Intelligence, Sive can fall back to Apple's on-device model when there is no connection.

Is my data private?

Your plan is stored on your iPhone and backed up to your own private iCloud. Sive runs no database about you and never receives your plan. When you send a message to the assistant, that message is passed to an AI model operated by Google to be read. It is not used to train anyone's AI model, and no message or reply is stored on Sive's side.

How is Sive different from a regular to-do or calendar app?

You don't fill in forms. You write or say things the way they come to mind, several at once, and Sive works out which ones are timed events, which are reminders and which are plain to-dos, including the dates and times. You can then change or ask about your plans in the same plain words.

Can I use Sive with my voice?

Yes. Tap the microphone and speak; Sive punctuates your dictation and turns spoken lists into proper lists. In Settings you can make voice the default, so opening the chat starts listening straight away.

Is there a free trial?

Yes. Sive is a subscription, and new subscribers start with a free trial. The current price and trial length are shown in the App Store and in the app before you subscribe.

How do I cancel my subscription?

Subscriptions are managed by Apple. Open the Settings app on your iPhone, tap your name, then Subscriptions, and choose Sive. You can also reach it from Settings, then Subscription, inside Sive. Cancel at least 24 hours before the free trial ends and you won't be charged.

What happens to my plans if I change phones?

If iCloud is on, your events, reminders and to-dos are backed up to your private iCloud and appear on your new iPhone when you sign in with the same Apple Account and install Sive.
