This is Spartan, Microsoft’s new browser to challenge Google Chrome

At Microsoft’s Windows 10 event today, the company unveiled its all new browser that will be alongside Internet Explorer in the next OS: Spartan.

Spartan is based on a fork of Microsoft’s Trident rendering engine, which is also found in Internet Explorer.

The browser allows you to collaborate with others by marking up with drawing on the page directly. You’ll also be able to click anywhere on the page and comment.

The browser features a reading mode that automatically downloads articles for offline reading later, which is useful if you’re catching a flight without internet access.

Cortana is coming to the browser too, and can learn from your habits and give you details about specific things that it thinks relevant, just like Google Now does on Android.

Joe Belfiore, Corporate Vice President of Operating Systems at Microsoft. said that Spartan is the current codename and will likely change before the release.

It’s not clear exactly when Spartan will be available, but Belfiore said the features will roll out “over the next few months.”
