SeferAI searches Sefaria's library — Tanakh, Talmud, Midrash, Halakhah, Kabbalah and commentary — and writes you a synthesis with every claim linked back to the text it came from. Then it can read it aloud.
These are unedited answers from the public library, written by SeferAI for people who asked. No account needed to read them.
Three steps. The first one is the only one that needs anything from you.
In plain English or Hebrew. A verse, a sugya, a theme across sources, or something you have been chewing on all week.
A structured answer, with inline citations that link straight to the primary text on Sefaria. You can check every claim.
Turn it into a narrated podcast episode you can play on a walk, or subscribe to in any podcast app. This step needs a free account.
A question is matched against passages, not against page titles. So how many passages there are, and in which language, is most of what determines whether the right source comes back.
| Where the depth went | Texts (EN+HE) | Passages |
|---|---|---|
| Commentary — Rishonim, Acharonim, modern | 6,116 | 2,365,241 |
| Halakhah | 383 | 227,592 |
| Talmud | 187 | 204,158 |
| Liturgy | 87 | 196,662 |
| Chasidut | 162 | 170,009 |
| Responsa | 163 | 140,279 |
| Jewish Thought, Kabbalah, Midrash, Musar | 449 | 349,912 |
| Tanakh, Targum, Mishnah, Tosefta, Second Temple | 528 | 148,675 |
The depth is concentrated where the old index was thinnest: commentary. Asking what the Rishonim make of a verse now has six thousand commentary texts behind it rather than a sample of the English ones.
They are separate choices, and neither one is a trap.
You can ask and read without signing in, and it is free. Those questions and their answers join the public study library, where anyone can read them — that library is how most people find this site. Making a podcast is the one thing that needs an account, because it costs real money to narrate.
Sign in with your email — no password, we send you a link — and your syntheses stay private unless you choose to share one. Signing in is free.
SeferAI is not trying to make a profit. Every question costs real money to answer — model time, and narration for the podcasts — and support is what keeps it running and free for people who cannot pay.
Prefer to give once rather than subscribe? A one-off contribution helps just as much.
Curious what the Ultra tier actually produces? Listen to three full episodes — no sign-up, and each comes with the written study behind it.
Your question is turned into a vector embedding and matched against a database of Sefaria's texts — about 3.8 million passages, in Hebrew and English, from Tanakh, the Babylonian Talmud, Midrash, Halakhah, Kabbalah and commentary. Matching happens by meaning rather than keywords, so a question about forgiveness surfaces passages that never use the word.
A frontier large language model reads the retrieved passages and writes the synthesis from them, citing as it goes. It works from the sources it was given rather than from memory, which is what makes the citations checkable — and why you should check them.
Yes. SeferAI is available as a connector for Claude, so you can search all 3.8 million indexed passages from inside any Claude conversation and get the references back with links. How to connect it.
Sefaria is the open library of Jewish texts that SeferAI draws from, and it is a separate organisation. Syntheses are study aids produced by a language model. They are not rulings, and they should be attributed to SeferAI rather than to Sefaria or to any authority quoted inside them.
