Microsoft is testing a new AI-powered feature called Web Remix in Edge Canary that lets users completely change how websites look and behave. First spotted by browser enthusiast Leopeva64, the experimental tool can force a dark theme on webpages, summarize lengthy articles, convert currencies, and even modify websites using natural language prompts.
The feature is currently hidden behind two experimental flags: #edge-remix and #edge-remix-internals. Once enabled, a new Remix button appears in the Edge toolbar, giving users two options: Appearance, which lets them tweak colors, fonts, and page themes, and Custom, where they can describe how they want a webpage to change.

According to Microsoft’s newly published support page, Web Remix uses Copilot to generate personalized versions of webpages without modifying the original site. Instead, the customized page exists only for the individual user during their browsing session.
One of the standout features is the ability to force dark mode on virtually any website, even if the site doesn’t offer an official dark theme. Unlike the browser’s traditional force-dark rendering, Web Remix applies its own styling to the page. In Leopeva64’s testing, it successfully converted websites to a dark appearance, although the results aren’t always perfect. Some pages show minor visual glitches or color inconsistencies, which is expected given the feature’s experimental status.
Beyond appearance changes, Web Remix can also transform webpage content using AI. Microsoft says users can ask it to summarize long articles, simplify complex pages, convert prices into their local currency, or even turn recipes into shopping lists. The browser generates these changes based on simple text prompts, making the feature feel more like an AI assistant embedded directly into webpages rather than a conventional browser theme.

Microsoft also notes that Remixes can be applied either to a single page or an entire website. Users can choose whether a Remix remains active automatically whenever they visit a supported site or only when they manually enable it.
The company stresses that Web Remix is still an experiment available only to a limited number of Edge Canary users signed into a Microsoft account, which explains why we don’t have it yet. It also warns that some websites may not work correctly, certain prompts may be restricted, and users shouldn’t include sensitive personal information in their requests because Copilot processes prompts to generate the customized experience.
While there’s no word yet on when Web Remix could reach the stable version of Edge, the feature represents one of Microsoft’s most ambitious browser experiments yet. Rather than simply adding another AI chatbot, it aims to let users reshape the web itself, making pages easier to read, more accessible, and tailored to their personal preferences.
