Socratic is a discontinued education tech platform that used artificial intelligence to help students with their homework by providing educational resources like videos, definitions, Q&A, links and more.
Socratic was first launched as a web product in 2013 by Chris Pedregal and Shreyans Bhansali, in New York City, United States. They launched their app under the same name in 2016.

Creative Commons (CC) is an American non-profit organization and international network devoted to educational access and expanding the range of creative works available for others to build upon legally and to share. The organization has released several copyright licenses, known as Creative Commons licenses, free of charge to the public, to allow authors of creative works to communicate which rights they reserve and which rights they waive for the benefit of recipients or other creators. Content owners still maintain their copyright, but Creative Commons licenses give standard releases that replace the individual negotiations for specific rights between copyright owner (licensor) and licensee, that are necessary under an "all rights reserved" copyright management.
As of 2019, there were "nearly 2 billion" works licensed under the various Creative Commons licenses. Wikipedia and its sister projects use one of these licenses. According to a 2017 report, Flickr alone hosted over 415 million cc-licensed photos, along with around 49 million works in YouTube, 40 million works in DeviantArt and 37 million works in Wikimedia Commons. The licenses are also used by Stack Exchange, MDN, Internet Archive, Khan Academy, LibreTexts, OpenStax, MIT OpenCourseWare, WikiHow, TED, OpenStreetMap, GeoGebra, Doubtnut, Fandom, Arduino, ccmixter.org, and Ninjam, among others, and formerly by Unsplash, Pixabay, and Socratic.
