Apple is using Apple Intelligence to let Safari users generate their own browser extensions from a plain-English prompt, an attempt to close the years-long extension gap between Safari and Chrome, Edge, and Firefox. The feature, shown at WWDC 2026 on June 8, lets a user describe what they want a Safari extension to do, and the browser builds it. It is the most aggressive AI move Apple has made in Safari, which until now offered only webpage summaries through the Highlights feature.
In Apple's demo, the prompt asked Safari to build a recipe tracker with a toolbar button, saved entries, and per-recipe notes. Safari produced a working extension called Recipe Keeper that did each of those things. The pitch is straightforward: rather than wait for a third-party developer to ship a Safari port of a Chrome or Firefox extension, the user describes the tool and gets it.
Safari's extension library has historically lagged Chrome and Firefox by a wide margin, a gap Apple has long attributed to its stricter developer requirements. Letting users generate their own one-off extensions sidesteps that bottleneck entirely. It also slots into a broader trend of personal software built on demand with AI, aimed at users who want a single utility rather than a polished marketplace product.
Key facts
- 01Apple demoed a Safari feature at WWDC 2026 that generates browser extensions from a natural-language prompt using Apple Intelligence.
- 02The demo prompt built a 'Recipe Keeper' extension with a toolbar button and notes, end-to-end from a single description.
- 03Safari is also gaining AI tab grouping, a 'Notify Me' page-change watcher, and automatic compromised-password repair via the Passwords app.
- 04Google shipped a similar Chrome tab-grouping feature in 2024 but appears to have discontinued it.
- 05Until this update, Safari's only consumer AI feature was webpage summaries via Highlights.
Tab management is getting an AI layer too. Safari will automatically sort open tabs into categories based on their content, so a cluster of running-shoe pages might be grouped under 'sneakers' without any manual labeling. Google rolled out a comparable Chrome feature in 2024, though its dedicated page now redirects to a generic support article and the option appears to have been pulled. Microsoft Edge groups tabs by relevance, and Mozilla Firefox uses AI to name tab groups.
Apple is also bringing automatic password repair to Safari. When the Passwords app detects a compromised credential, it can now use Safari and Apple Intelligence to navigate to the affected site, sign in, and rotate the password on the user's behalf. Google launched a similar feature for Chrome last year, limited to a list of supported websites. Apple did not detail its site coverage.
A new 'Notify Me' feature lets users describe the kind of webpage change they want to track, such as a product restock or a price drop, rather than firing on every diff. Several third-party tools already monitor page changes, but the natural-language filter is meant to cut the noise that has made those tools impractical for most users. It is the same prompt-as-config pattern that runs through the extension builder.
Taken together, the Safari updates are a notable shift for a browser that had until this release offered almost no consumer-facing AI. Chrome, Edge, and Firefox have spent the past two years stacking AI features at speed while Safari fed Apple Intelligence into its products at a much slower pace. The WWDC 2026 batch is Apple's clearest attempt to catch up without copying rivals feature-for-feature.
The open question is reliability. User-generated extensions live or die on whether the generated code actually works against the messy reality of the open web, and Apple's demo is a controlled best case. Browser extensions also touch sensitive surfaces, including page content, cookies, and saved data, which raises the stakes for any auto-generated code that ships into a user's daily browser. Apple did not detail what sandboxing or review applies to vibe-coded extensions, or what happens when an extension misbehaves.
Apple's caution is showing in what it did not ship. There is no Safari equivalent of an agentic browsing mode, no in-page chat assistant, and no autonomous task runner of the kind rivals have been demoing. The company is picking a small number of features it believes work and leaving the rest on the shelf, a posture consistent with the rest of its Apple Intelligence rollout this cycle, including the Siri overhaul and the Photos and Image Playground updates the site covered earlier this week.
The strategic read is that Apple is trying to convert Safari's biggest weakness, its thin extension catalog, into a structural advantage by making every user a developer of one. If the generator works reliably, Safari stops needing parity with the Chrome Web Store, because the long tail of niche utilities can be conjured on demand. If it does not, Apple has handed competitors a clean line of attack and added a new class of buggy code to the browser that ships on more than a billion devices. The next twelve months of real-world use will decide which version of that story holds.
