The core**: the study method loaded before answering any religious question — sources actually read, exact quotes, [hebrewbooks.org](https://hebrewbooks.org) reading links
HebrewBooks catalog search (~65,000 scanned seforim) by title/author via their official API — requires a `HEBREWBOOKS_API_KEY` (granted on request: developers@hebrewbooks.org)
Study register — `debutant` (all in French, every term explained, for readers with no background or no Hebrew), `classique` (bilingual, default), `avance` (beit midrash: original text, no glosses, mahloket, girsaot, lomdus). Same source discipline in all three
Study-partner mode: Claude asks the questions, makes you defend Rashi against Tosafot, never hands out answers
AlHaTorah-style weekly study guide: aliyot, three textual questions with diverging commentators, haftarah echo, Shabbat-table questions
MCP App: an interactive Vilna page in the conversation (Gemara, Rashi, Tosafot, click-to-translate). Also at `/daf
Text of any reference (Hebrew + translation — **French first when Sefaria has it**, e.g. Bible du Rabbinat for Tanakh, else English): `Berakhot 2a`, `Shulchan Arukh, Orach Chayim 1:1`…
Linked commentaries and sources (Rashi, Tosafot, midrash, halakhah…), filterable by category
Full-text search across the whole library (Hebrew or English)
Parashat hashavua, haftarah, daf yomi, daily Rambam…
