Siri is built into every iPhone. With iOS 27, it became a smarter assistant that can understand what's on your phone and hold a real conversation.
Kiwi does something different. It doesn't wait to be asked. It notices what needs doing, texts you first, and does it when you say yes, on any app or website.
The short version: Siri is great for quick things you ask for on your iPhone. Kiwi is the assistant that comes to you first and handles the errands, on iPhone or any phone.

Kiwi comes to you
Siri is ready whenever you call it. But you still have to remember what to ask.
Kiwi keeps an eye on your calendar and email, and messages you once, at the right time, when something needs doing:
Your Saturday afternoon is free. Want me to plan something with the kids?
You reply "yes", and Kiwi finds the options and books what you choose. You never had to think of it.
It goes beyond your phone
Kiwi works on the apps you already use, like Gmail, Outlook, Google Calendar, Slack, Spotify and Uber, and when there's no app for something, it uses the website for you. It books the ride, orders dinner, reserves the table, replies to the email and cancels the subscription you forgot about.
Anything that costs money shows its price first. Kiwi only says something is booked once the company confirms it.
On any phone, in any language
Siri lives on Apple devices. Kiwi works in Messages on an iPhone and in WhatsApp on any phone, so the whole family can use it, whatever they carry. And Kiwi answers in the language you write in.
Better together
You don't have to choose. Kiwi is a contact in your Messages, so it fits right into your iPhone. Use Siri for a quick timer or a call. Let Kiwi take care of the things you'd otherwise have to remember: the delayed flight, the reply you're waiting for, the free afternoon.
