Sefaria is an online open source free content digital library of Jewish texts. It was founded in 2011 by former Google project manager Brett Lockspeiser and journalist-author Joshua Foer. Calling itself "a living library of Jewish texts", Sefaria relies on volunteers to add texts and translations. Texts are provided under a free license both in Hebrew and in translation. The website also provides a tool for creating source sheets.
Sefaria is a non-profit organization.
Sefaria was originally founded in 2011, by Joshua Foer, and Brett Lockspeiser, a former product manager at Google. The site's first beta was released in 2012. The company was formally incorporated in 2013, with funding from the Natan Fund, Jonathan and Tamar Koschitzky, and the Jim Joseph Foundation. In 2014, engineers at Sefaria created a data visualization, showing the many connections between the Tanach and Talmud. By 2015, twelve apps used Sefaria's API and database. Also in 2015, Sefaria reached a deal to use Urim Publications' translations of the Tanakh and commentaries. Sefaria's website received a major redesign in 2016, alongside the release of new apps for iOS and Android, and a complete English translation of Rashi's commentary on the Torah. By this point, over a dozen people were part of the website's staff. Sefaria reached a major milestone in 2017, with the release of the Willam Davidson Talmud.
Sefaria has a vast library of Jewish text, including Tanach, Talmud, and Jewish prayers alongside newer works. Sefaria's content comes from a variety of sources. Books in the public domain are scanned and processed by OCR software, which a team corrects and formats. Other online sources such as On Your Way are also used. Some publishers have also provided works directly to Sefaria.
Some works, such as Tanach and the Talmud even feature English translations. These are either crowdsourced, provided by publishers, or in the public domain. Some translations are even written by Sefaria.
Many works are linked with their respective commentaries. For example, clicking on a verse in Tanach will open a window on the side, allowing the user to open a commentary on that verse.
Sefaria's Source Sheet Builder allows users to create a page with source text from Sefaria. Source Sheets can be made public, and available for other users, or can be downloaded as a PDF and printed.
