In an announcement the company said that the app had originally been launched on the iPad "to make browsing news on mobile devices faster, simpler and more beautiful than ever before", but it added that users were also keen to "share or save stories" on the web.
Kothari told Journalism.co.uk that over the past year the ability to use Pulse on a web browser has been "the biggest request from people".
With the launch of the web app now under Pulse's belt Kothari added that "in some ways the web is our final frontier".
Kothari said the browser platform had been designed and built "from the ground up".
While the features and sources of Pulse remain the same, with users able to select subject types and add news sources, the design has been centred on the way users consume news on web browsers compared to mobile or tablet apps.
For example, Kothari said it was important for users not to have to browse horizontally, so the Pulse reader fits to full screen no matter what size users have their browser.
According to the announcement about the launch of Pulse for the web also "works seamlessly with highly acclaimed mobile apps on iPhone, iPad, Android or Kindle Fire".
"Easily synchronise all your content sources and stories with one simple account. Adding a source from your browser automatically adds it to your devices and vice versa; you never have to think about managing your subscriptions again."
It has also been "optimised for touch on Windows tablets" and IE10, the announcement adds.
In June Pulse also announced a new 'premium sources' service which offers users the choice of subscribing to premium content from the Wall Street Journal.
