What if you could use AI without sending your data to the cloud?
Introducing WebAI, a set of browser APIs that lets developers integrate locally running AI models into websites and extensions they build.
It’s opening up new possibilities - now in early preview in Opera One and Opera Neon, with Opera GX to follow.
🧵 Here's how it works.

We've already built six experimental extensions to show what's possible.
A few examples:
• Project Lens highlights parts of articles relevant to your work.
• Got It? turns articles into quizzes.
• Semantic Art transforms written content into moving visual art.
These are just experiments. Imagine what developers could build next.

We’ve been building browsers for over 30 years, and we still get excited when someone tries something different. Arc did just that, and we’re sad to see it go.
If you’re part of the Arc community and looking for your next browser, we’d love to welcome you to Opera. We’ve got a few things you might like:
• Vertical Tabs & Workspaces
• Split Screen (up to 4 tabs!)
• Tab Islands
• Free, built-in VPN & Ad Blocker
We've decided to sunset Arc on December 22, 2026.
That's not an easy sentence to write. We spent years building Arc and celebrating each and every release along the way: we have so much pride and love for what we made alongside the Arc community.
Our priority is to deliver best-in-class security for our members. Keeping a browser secure takes constant, dedicated work that is only increasing in the age of AI. Dia was built from the ground up to meet today’s security standards, so that's where our engineering and security teams will focus moving forward.
We've worked to make switching to @diabrowser as easy as possible for Arc members. Here's how:
· Your passwords, bookmarks, extensions and history come over to Dia seamlessly.
· Spaces, Folders, and Tab Groups are in Dia and import over with your data intact.
· Dia now surpasses Arc benchmarks in stability, speed, and security.
· The browser features you use in Arc are free in Dia, and the AI is optional.
Thank you for using Arc, for pushing us to make it better, and for building alongside us. The team that made Arc is the same team behind Dia, and some of our most ambitious work is just ahead. We'd love for you to be there with us when it lands.
