Chrome 157 Hits Beta With Language Detector on Android

The Chrome team promoted Chrome 157 to the Beta channel for Windows, Mac and Linux today. The build is 157.0.8103.6, and the Chrome Releases Beta note points readers to the Chromium blog and the change log for what is new.

Android users on the Beta channel already got 157.0.8103.5 yesterday, per the Chrome Beta for Android update. Stable for 157 is scheduled for November 3, 2026, according to Chrome Platform Status.

What stands out in Chrome 157

Language Detector on Android: The Chrome 157 release notes say the Language Detector JavaScript API is now exposed on Chrome for Android. Sites can detect text language on the device with an on-device model, without sending the text to a cloud endpoint. Desktop Chrome already had this built-in AI API. Android support is the new piece in 157.

How it works: Developers check for LanguageDetector in the browser, call availability(), then create() and detect(). Chrome’s Language detection docs explain ranking results with a confidence score. Short phrases are less reliable, so apps should treat low confidence as unknown.

CSS and layout: 157 adds CSS corner shorthand properties (set border-radius and corner-shape per corner), text-decoration-inset for underline spacing, and a custom string for text-overflow (for example showing “(more)” when text is clipped).

HTML-in-canvas: a new set of primitives lets pages customize how HTML renders into a canvas, including layout, drawing, and sync between the DOM and the canvas.

Other platform changes: Background Fetch now enforces CORS, ProgressEvent is available in service workers, and Capability Elements gain an icon-only display mode. The same release notes list the full set.

Who gets Chrome 157 right now

How to try Beta: On Windows, Mac or Linux, install Chrome Beta from Google’s Chrome channels page, or keep a separate Beta install so your Stable profile stays untouched. On Android, install Chrome Beta from Google Play. ChromeOS Beta was still on browser 156 in the October Chrome Releases index.

Our take: This is a developer-heavy Beta more than a consumer redesign. The practical headline for Chromebook and phone users is Language Detector reaching Android Chrome. Casual Stable users can wait for November 3 unless you test Beta builds on purpose.
