👋 Hi Bluesky! I've opened github.com/bluesky-soci... that adds built-in translation as a progressive enhancement on browsers that ship the Translator API developer.chrome.com/docs/ai/tran... (Chrome 138+). On other browsers, it falls back to the present behavior of linking to Google Translate.

We're excited to announce the release of version 0.0.10 of our TypeScript types for Built-in AI APIs, now featuring support for the brand-new Proofreader API! Check it out and upgrade today: www.npmjs.com/package/@typ... @tomayac.com #BuiltinAI #WebAI

In #WebAssembly spec news, #Wasm 3.0 is complete 🎉! Read all about it in Andreas Rossberg's article: webassembly.org/news/2025-09....

On the Chrome team, we've a cool new origin trial for you to try in your apps: the Proofreader API: developer.chrome.com/docs/ai/proo.... ❌ tyop → ✅ typo ```js await (await Proofreader.create({ expectedInputLanguages: ['en'], })).proofread( 'Let us knwo how it foes', ); ``` #BuiltInAI #WebAI

For anyone understanding 🇩🇪 German: we recently did a whole podcast episode with @tomayac.com on all these APIs (also talking about how Google and Microsoft back them with their individual own LLMs, Gemini / Phi): workingdraft.de/677/

Did some exploration around stress-testing the multimodal capabilities of the Prompt API and found out that apparently it's quite 🎨 color-sensitive: blog.tomayac.com/2025/09/16/p.... Not something super actionable, other than maybe a heads up to play with color-preprocessing.

For all that's holy, can you just leverage the Web, please? 🔗 blog.tomayac.com/2025/09/03/f... A blog post about our washing machine and registering it, so we get 10 years of warranty. Featuring call center hell, website hell, customer comms hell, and an actually useful #WebAI feature with demo.

I had the honor of being on the @workingdraft.de podcast again to chat about built-in AI APIs we're working on in Chrome. Give the episode a listen 🎧!

📢 New blog post: What a diff'rence a semicolon makes: blog.tomayac.com/2025/07/26/w.... Hat tip to André Jaenisch (not on Bluesky?) and @chriscoyier.net for pointing me at (André) and creating (Chris) the Web Development Merit Badges that I'm mentioning in the post.
