Quip 2.0 also has revamped navigation that should make it easier to switch between documents and chat threads, and to find frequently used documents. It's also now possible to export any Quip document to Microsoft Word.
Quip has plans to launch spreadsheet and presentation applications later this year, giving it a suite with the three core productivity components.
The desktop browser-based version of Quip works well on Safari, Chrome and Firefox, but it hasn't been optimized yet for Internet Explorer. There are mobile applications for iPhone, iPad and Android devices.
Quip, which has about 15 employees and raised $15 million in Series A funding, is taking on Microsoft, Google and the many vendors offering office productivity suites for tablets, smartphones and PC browsers, and that promise improved collaboration via cloud computing.
In April, Quip released an API in the hopes that enterprise developers will use it to make the product more useful and versatile in workplaces.
Taylor said Quip is being used by hundreds of thousands of users, who have created millions of documents.
The word processor app is free for up to five users on desktop browsers and iOS and Android smartphones and tablets, and it includes the ability to create shared folders. Quip Business costs US$12 per user, per month for unlimited users and includes other features such as shared team workspaces, adding and removing users, and flagging external sharing. Quip Enterprise, whose price must be negotiated with Quip's sales team, adds more IT administration capabilities, such as single sign-on, usage stats and security features.
