SeferAI: ask about Jewish texts in English, Hebrew, German, Russian, Ukrainian, French, Spanish or Portuguese, and get an answer that cites its sources

An independent study tool searches about 4.05 million passages of Sefaria's library, writes a sourced synthesis in the language of the question, and can turn it into a podcast

September 2026 | SeferAI

SeferAI, a study tool for Jewish texts at seferai.org, now answers questions in eight languages. A reader can ask in English, Hebrew, German, Russian, Ukrainian, French, Spanish or Portuguese and receive the answer in the same language, and the whole site can be switched between the eight.

Every answer is a synthesis drawn from Sefaria, the open library of Jewish texts: about 4.05 million passages in Hebrew, English, German, French and Portuguese from Tanakh, the Talmud, Midrash, Halakhah, Kabbalah, Chasidut, responsa and commentary. Each claim carries a citation that links to the primary text on Sefaria, so it can be checked.

What SeferAI does

  • Sourced answers: a structured synthesis with inline citations to the primary texts
  • Eight languages: questions and answers in English, Hebrew, German, Russian, Ukrainian, French, Spanish or Portuguese
  • Podcasts: any synthesis can be narrated as an episode, with a personal feed for any podcast app
  • Study tools: mind maps, study guides, flashcards and quizzes built from a synthesis
  • Public study library: questions others have asked, readable by anyone
  • Everywhere you read: the web, an app for iPhone and iPad, and a connector for Claude

Where a translation stands between the reader and the source, SeferAI says so. Sefaria publishes German, French and Portuguese translations of many texts, and German, French and Portuguese answers quote them directly. There are few Spanish and almost no Russian or Ukrainian translations on Sefaria, so a Spanish, Russian or Ukrainian answer is written from the Hebrew and English sources and translated, and it carries a note saying that it was.

"The point of SeferAI is to bring a reader as close as possible to the sources themselves, with the language model as a layer of synthesis on top. Being open about where a translation was made is part of that."
— the SeferAI team

Finding the right source is most of the work. SeferAI restates each question in the terms the texts themselves use - the Hebrew words, their variant spellings and the books where a topic is discussed - searches the full text of the library for them, and has a language model put first the passages that address the question directly. A search by meaning fills in where the words alone find too little.

Asking and reading are free and need no account; questions asked without an account join the public study library. A free account keeps a reader's studies private and makes podcasts. Premium and Ultra-Premium subscriptions add better narration, two-voice conversational episodes and the study tools, and pay for the model time behind every answer.

About Sefaria and SeferAI

Sefaria is a separate, independent organisation whose openly licensed library SeferAI draws from. SeferAI's syntheses are study aids written by a language model. They are not rulings, and they should be attributed to SeferAI rather than to Sefaria or to any authority quoted in them.
