Instapaper is a bookmarking service that allows web content to be saved so it can be "read later" on a different device, such as an e-reader, smartphone, or tablet. It was founded in 2008 by Marco Arment. In April 2013, Marco sold a majority stake to Betaworks[1] and by mid 2016 Pinterest acquired the company. In July 2018, ownership of Instapaper was transferred from Pinterest to a newly formed company Instant Paper, Inc. The transition was completed on August 6, 2018.[3][4]

Instapaper started out as a simple web service in late 2007 with a "Read Later" bookmarklet and stripped-down "Text" view for articles. When Marco Arment launched the service publicly on January 28, 2008,[5] its simplicity rapidly earned accolades from the press, including Daring Fireball[6] and TechCrunch.[7]

In April 2013, Arment sold a majority stake in Instapaper to Betaworks.[1] Afterward, the service's web interface was redesigned.[8]

On August 23, 2016, Instapaper was acquired by social networking service Pinterest. The service will continue to operate, and the Instapaper staff will work on development for both Instapaper and Pinterest. On November 1, 2016, Instapaper announced that it would discontinue its subscription model and offer its "Premium" features to all users.[9]

On May 23, 2018, Instapaper announced that it had suspended its services for residents of the European Union in order to address compliance with General Data Protection Regulation (GDPR) requirements.[10] Service was restored on August 7, 2018.[11]

Instapaper can be used via a web-based interface, or through mobile apps for Android and iOS. Within a web browser, a "Read Later" bookmarklet can be used to save pages to a user's personal unread queue on Instapaper. Every article is automatically reformatted to remove excessive formatting and graphics.[12]

Instapaper was initially distributed as a paid app. Later, the app became a free service, but with certain features exclusive to a "Pro" version of the app, and later an "Instapaper Premium" subscription, such as ad-free browsing, full-text search, and voice dictation on supported platforms. These features became free for all users on November 1, 2016.[9]

Instapaper's free iPhone app (removed from the App Store on March 12, 2011[13]) with offline reading was one of the first apps in the App Store on July 12, 2008.[14][better source needed] Instapaper's paid app, then called Instapaper Pro, launched shortly afterward on August 26, 2008 and introduced tilt scrolling, which automatically scrolls a column of text when the device is tilted slightly up or down.[15]

On March 10, 2011, with the launch of the 3.0 app, Instapaper added social sharing and browsing features.[16] Later in 2011, the redesigned 4.0 app added full-text search of all saved articles for customers with the optional $1/month subscription.[17]

The Instapaper iPad app launched with the iPad itself on April 3, 2010.[18][19]

The Instapaper for Android was built by development shop Mobelux[20] in 2012 and supports Android phones and tablets.

An automatic send-to-Kindle feature was added on March 8, 2009.[21] The Kindle feature alone is used by over 60,000 Kindle owners as of late 2011.[22] Manually sending individual articles, or digests of recent articles, from the Instapaper app is currently a Subscriber feature.

On June 1, 2008, Instapaper launched Give Me Something to Read, a standalone website that featured a few high-quality, longform, nonfiction articles every day from Instapaper's most frequently saved articles.[23]

Unlike a conventional social news website, which carries stories posted automatically by popularity, Give Me Something to Read is human-edited. Marco Arment was the editor for the site's first year. On July 27, 2009, Arment hired Richard Dunlop-Walters as a part-time contractor to take over as editor.[24][permanent dead link] As of March 2011, Dunlop-Walters was Instapaper's only employee besides Arment.

On March 22, 2012, Give Me Something to Read was renamed The Feature.[25] The articles are still hand-picked, and they are featured in Instapaper's website as The Feature, and in the iOS app as The Feature section.

Marco Arment observed about The Feature (formerly known as Give Me Something to Read):

The very similar Longform and Longreads both started significantly later than Give Me Something To Read but always got a lot more attention, with Longreads fueled especially by its active Twitter presence. They’ve both done great things, but I always believed that Give Me Something To Read deserved a similar level of attention that it never seemed to achieve.[26]

Instapaper has been positively reviewed by publications including The New York Times,[27] The Wall Street Journal,[28] PC Magazine,[29] Macworld,[30] and Wired.[31][18]

Instapaper is one of several "read it later"[32] (also known as "read later"[33] or "saving"[28]) services. In November 2013, Mashable named Instapaper and the following four clients as the "5 Best Read-It-Later Apps";[34] they all support a variety of devices and other apps.
