Mozilla is introducing a new artificial intelligence tool for iPhone users, enabling them to shake their device for a quick summary of the webpage they are viewing. The feature, called “shake to summarise”, will begin rolling out this week and is designed to make browsing more convenient.
How the feature works
The tool will use Apple’s on-device AI model, but only on iPhone 15 Pro or newer devices once iOS 26 becomes available. For users on older iOS versions, Mozilla will rely on its own cloud-based AI system to generate summaries. These will appear over the top of the webpage being read.
In addition to shaking the phone, users can trigger an AI summary by tapping the thunderbolt icon in the address bar or selecting “Summarise page” from the menu that appears when tapping the three dots at the bottom of the screen.
Mozilla has confirmed that the feature can be switched off at any time. This is intended to prevent accidental activations, such as when the phone is shaken unintentionally. Shake to summarise will only work on webpages containing fewer than 5,000 words, ensuring the summaries remain manageable and accurate.
Integration with Apple Intelligence
The launch makes Firefox one of the first major third-party applications to integrate with Apple Intelligence, Apple’s forthcoming suite of AI tools. More details about Apple’s AI system were expected to be revealed during today’s iPhone launch event.
By leveraging Apple’s on-device AI, Firefox users with newer iPhones will benefit from faster responses and greater privacy, as their data will not need to be sent to the cloud for processing. Those on older devices will still gain access to the feature, though the processing will take place on Mozilla’s servers instead.
Availability and plans
At launch, the “shake to summarise” feature will be available only to users in the United States, and it will work exclusively in English. Mozilla has said that wider availability is planned, with future updates expected to bring support for more regions, additional languages, and Android devices.
The introduction of shake to summarise highlights Mozilla’s efforts to stay competitive in the mobile browser market by embracing AI-powered tools. The feature aims to save users time when browsing lengthy articles and documents, making information more accessible at a glance.
