Rashi on the Chumash by parsha, perek and pasuk: every French word with its reading from Catane, the printed text and a manuscript, plus his grammar points, his settling of the verse and his use of the Targum, with a place for your own notes.

The hard and rare words of the Chumash, parsha by parsha: each word in its pasuk, how often its root appears in the Torah and in all of Tanach, every form of it that Tanach uses, and a conjugation builder that explains each binyan and tense. Forms Tanach never uses can be filled in, and are marked as not in the text.

Every complaint and rebellion of Klal Yisroel in the midbar — what happened, how Hashem and Moshe answered, what Moshe was mispallel for, and what it cost — with the machlokes over which fall among the ten nisyonos.

All the countings of Klal Yisroel on one sheet — the eight counts in the Torah, the countings in Nach, and the one still to come, le’asid lavo — with the midrash of the ten countings brought as written.

Who is assur to whom and why — the forbidden relationships laid out on the family tree itself, with the thematic categories toggled over it.

Dinah’s age at Shechem worked out link by link: a slider for each assumption, every opinion marked on it with its words quoted, and a warning when the slider stands where no source holds. Shows which sets of opinions fit together and which cannot.

The 44 sources of tumah — avi avos, avos, and toldos — what each one is, what it makes tamei, how far the tumah travels, and the way back to taharah.

Which mark is tahor, which needs hesger, and which is muchlat — the step-by-step din of negaim of the person, of clothing, and of houses.

The defects that bar a kohen from avodah and an animal from the mizbeach — each term of Vayikra 21–22 with its pasuk, Rashi brought as written, and the machlokesin over what the words mean.

The avodos of the Kohen Gadol from morning to night, as a departures board — following the Rambam’s seder, with a toggle for the Mishnah’s. Hebrew interface.

Which locusts are kosher and how to tell — arbeh, sol’am, chargol, and chagav, the leaping-leg simanim, and a checker to work through a specimen.

What horns tell you about kashrus — the simanim that distinguish a chayah from a beheimah, keyed to the horn’s anatomy.

Every insect and parasite that gets into food — in water, fish, produce, and meat — set against the sugya of tolaim: was it born in its place, or did it come from outside and separate. Each creature is placed in its category in the Gemara and Shulchan Aruch, the machlokes is left to the poskim, and a live scientific reading of the organism sits alongside.

Scan the kosher symbol on a package or a restaurant certificate and see whether the agency is on the cRc recommended list, and on any list you add. With the restaurants, bakeries, caterers and stores that the major agencies list as certified, searchable by state, hechsher, meat or dairy, and kind of place.

One shared database of Seder-Zeraim plants, sortable by taxonomy — with each masechta layering its own aspects onto the same crops: Kilayim pairings, Terumos, Maasros, and Maaser Sheni. A juxtaposition graph sets the three tithes side by side by produce category, and every crop carries the ripening stage from which it becomes chayav. Mishnah and Rambam brought verbatim with source links; the science is a springboard.

The original Kilayim-only view: every plant named in Maseches Kilayim — the Mishnah and Rambam brought as written, what each plant is according to the scholars who studied them, and why the pairs are or are not kilayim with one another.

What each of the four species is doing as a plant, set against what the sugya asks of it: grafting versus cross-breeding versus cross-pollination in the esrog and what DNA can and cannot see, why the pitom stays or falls, what makes a Deri lulav a Deri, how rare a truly three-leaved myrtle is and why, the willow’s field key, and a blemish guide that reads black dots, brown scars and chazazis region by region. Mishnah, Gemara, Shulchan Aruch and Magen Avraham brought verbatim with source links.

Every Mishnah in Maseches Beitzah with what the Gemara teaches in it beyond the written words: the case it is set in, the term it defines, where the machlokes really lies, the reason left unstated, and where the halacha goes elsewhere. Each teaching is quoted verbatim, linked to its daf, and tagged by kind, so one kind can be followed through the whole masechta.

All 139 mishnayos of Maseches Shabbos with what the Gemara teaches in each beyond the written words, in the same form as Beitzah: the case it is set in, the word it defines, where the machlokes really lies, the reason left unstated. Every teaching quoted verbatim, linked to its daf, tagged by kind, with a פירוש button that opens the Steinsaltz commentary for that line.

Every place Rashi and Tosafos quote a line of piyut: Rashi on Chumash, Nach and Shas, then Tosafos, with the Rishon’s words, the piyut as it stands in the machzor, and when in the year it is said. Ordered by the calendar from Rosh Hashanah or by sefer.

Every shitah for each zman of the day — degrees, fixed minutes, sha’os zmaniyos, horizon — computed live for your location, with the sources for each method inside.

The night the community in Mainz thought dawn had come while the moon was still shining. The sky over Mainz on Hoshana Rabbah for every year of the Maharil’s rabbinate: moonrise and sunset through the season, the moon’s orbit and brightness, and how a cloud layer turns a high moon into a false dawn, with time, moon height and year sliders.

Which haftarah is read when — the weekly haftaros, and the special Torah readings and haftaros of the moadim.

Pick a daf and see every sugya on it: where each begins and ends, the opening words brought as written, and links to the text and to a scan of the printed daf. Each sugya opens into a step-by-step scaffold, with the Gemara revealed line by line.
