In most enterprise environments, third party cloud-based STT is a non-starter. That usually leaves us with mediocre OS defaults.

My colleague @paul 's "Utter" Chrome extension fixes this by keeping the intelligence loop local. It uses the WebSpeech and Prompt APIs to transcribe and polish your "train of thought" entirely on-device. 🛡️✨

A productivity unlock for AI agent workflows without the data leakage.

Videos from the Web AI Summit coming soon!

In the meantime, here's the deck for "Beyond the demo: building the WebAI playbook." Let's validate ideas & UX patterns, fill tooling gaps, and write this playbook together.

Does your character wear a a monocle?

Before any of the built-in AI APIs in Chrome can be used, the underlying AI model and any customizations (such as fine-tunings) must be downloaded from the network 🌐, the compressed data be extracted 🗜️, and finally be loaded into memory 🧠. My new guide documents some of the best practices for improving the user experience as they wait for this download: https://developer.chrome.com/docs/ai/inform-users-of-model-download.

There are two embedded demos that show:

- Client-side only
- Hybrid implementation

I have attendee codes for the Web AI Summit in Sunnyvale on Oct 17. The Chrome Web AI team wants to meet you for the hallway track. Share your Web AI projects & pain points for a chance to get a code & help us with critical context engineering.

Agenda: https://rsvp.withgoogle.com/events/web-ai-summit-2025/sessions

Can't make it? No worries—the talks will be published a few weeks after the event.

On the Chrome team, we have an interesting new origin trial for you to try in your apps: the Proofreader API: https://developer.chrome.com/docs/ai/proofreader-api.

❌ tyop → ✅ typo

```js
const proofreader = await Proofreader.create({
expectedInputLanguages: ['en'],
});

const proofreadResult = await proofreader.proofread(
'PLease tryt his API and let us knwo how it foes!',
);
```

It's powered by Gemini Nano internally and part of Chrome's #BuiltInAI / #WebAI effort.

Thrilled to see the #BuiltInAI Translator API used by jimakuChan, a popular web app for streamers to generate live subtitles with translations.

This is exactly the vision: making powerful AI available directly in the browser. Users get fast, private, live translation for free—no complex setup needed.

Another win for #WebAI !
