How to Use Siri Knowledge

Use Siri Knowledge to find information and get answers to questions using just your voice, and learn how to phrase your requests to get the most relevant and accurate results.

How to Use Siri Knowledge

Siri Knowledge uses a combination of web searches, installed apps, and Wolfram Alpha to find answers to a variety of questions, provide definitions, deliver facts, and offer guidance on many topics.

When asked a question, Siri reads out and displays the answer in a notification rather than returning a list of search results in Google. Usually, you can tap on the notification for further details.

Use Siri to access a wealth of general knowledge

You can ask Siri a wide range of questions like “What is the capital of France?” or “How many moons does Jupiter have?”.

To begin, activate Siri on your device by saying “Siri” or “Hey Siri”, or press and hold the Home or Side button on an iPhone.

Here are some examples of the broad range of questions you can ask:

How does Siri Knowledge work?

Siri Knowledge interprets your requests using natural language processing (NLP). With machine learning, Siri attempts to understand the context and intent behind your questions and then searches for answers using data from multiple sources.

Siri is designed to understand follow-up questions and maintain the context of a conversation. For example, you could ask, “Who is the Prime Minister of Canada?” and then follow up with, “How old is he?” and Siri would understand that “he” refers to the Prime Minister.

How secure is Siri Knowledge?

Siri interactions are anonymized and not associated with your Apple ID. Additionally, Apple employs encryption and other security measures to protect your data.

What’s in the future for Siri Knowledge?

With repeated rumors about huge changes to Siri coming in iOS 18 and recent reports that Apple has reached a deal with OpenAI to integrate ChatGPT with Siri, it looks like Siri Knowledge could soon be getting a substantial and long-overdue upgrade.

In the meantime, you can already use Siri with ChatGPT by building a simple shortcut.
