Sefaria is an online open source,[1] free content, digital library of Jewish texts.

[3][12][13] Sefaria was originally founded in 2011 by journalist Joshua Foer and Brett Lockspeiser, a former product manager at Google.

[14] Sefaria's website received a major redesign in 2016, alongside the release of new apps for smartphones running iOS and Android, and a complete English translation of Rashi's commentary on the Torah.

[15] In 2020, the site announced a pilot program to introduce its model to some secular works such as American constitutional studies.

Books in the public domain are scanned and processed using optical character recognition software, which a team then corrects and formats.

[28][9] Source Sheets may be published online, within Sefaria's ecosystem, and they may also be downloaded as PDF files, which are easy to print.
