Mamash IA · source discipline for Claude

6,600titlesThe Sefaria library, read live at the moment of the question: Tanakh, Mishnah, Talmud, Midrash, Rambam, Shulchan Arukh, responsa, chasidut, and their commentators.

50,000seforimThe HebrewBooks corpus, searched inside the text and no longer by title alone: the passage, its page, and the facsimile to open.

0invented referencesThe rule is simple: what has not been read is not quoted, and every quotation comes with the link to check it.

An ordinary AI · answers from memory

It crossed these texts once, during training, and reconstructs them: approximate references, recomposed quotations, sometimes invented outright : with the same confidence in both cases, and without ever saying what it did not open.

Mamash IA · opens the book

The question triggers a reading: the text is opened in the Sefaria edition, quoted as it is written, with its exact reference, linked to its commentators and to the texts that depend on it. Verifiable precision, one click away : and, when a source is missing, the answer says so.

אThe manifesto, annotated in the margin

Assistants answer Torah questions from memory, with the confidence of one who has not opened the book. Mamash IA reverses the gesture: before any answer, your assistant loads a study method that obliges it to read the text, to quote it as it is written, and to say where to study it.

Because one does not learn alone, it also knows how to become a chavruta partner (the one who asks the questions rather than answering them), and to prepare the week's parashah like a worksite: aliyah by aliyah, machloket included.

And because study lives inside a Jewish day, it carries the everyday tools (zmanim, dates, gematria, nikkud, source sheets to share), and the whole library: Sefaria to read and connect, HebrewBooks to study from the scanned page.

And because the Torah does not belong to scholars alone, it speaks to each at their level: everything in plain English and every word explained for the beginner, the source in the original language and the lomdus for the one who has mastered it.

Why it matters

An approximate quotation is a false quotation. The discipline of the text is not a luxury: it is the condition of limud.

Everyday

Zmanim and Shabbat times, Hebrew dates, exact gematria, nikkud (Dicta), a source sheet ready for WhatsApp.

Usable online, no installation

Three modes

Beginner, classic, advanced : the register changes, the source discipline never does. Claude guesses your level from your question, and you switch modes with a word.

The sources

Texts, commentators and Sefaria search (licences displayed), and full-text search of the HebrewBooks corpus (~50,000 OCR'd seforim).

Works alongside Sefaria's official MCP

בThree modes, to each at their level

Beginner

No religious background, or no Hebrew.

Everything in English. No Hebrew word without its translation, context before the answer, one idea at a time, and no question ever judged naive.

“What is halakha, exactly?”

Classic

Basic background, Hebrew with translation.

Bilingual: the source, then its translation. English for the Bible. Common terms assumed known, standard references, machloket flagged. The default mode.

“What does Rashi say on this verse?”

Advanced

The beit midrash.

Source in the original language, terminology without gloss, rishonim and poskim, girsaot when they weigh, nafka mina, lomdus. Maximum density, nothing smoothed over.

“Shitat ha-Rambam against Tosafot here?”

One engine, one rigour: the texts are always actually read and quoted exactly. Only the register adapts, and you change it with a word. No Claude? Ask your question right here, in English: the answer is read in the texts, with its sources.
