Pick a masechta and a daf. The page brings the amud and maps every sugya on it, by the canonical passage divisions, with each opening quoted as written. Sugyos that carry in from the previous daf or run past this one are marked. Scaffold opens a sugya into its step-by-step moves, with the Gemara behind every step one tap away, and a second model can review the summaries against the words. Scaffolding runs free out of the box on the site's built-in models; the gear in the corner lets pro users pick stronger models with their own API keys.

Public or shared computer: do not remember keys here (a key you paste works only until this tab is closed)

Scanning a daf is free and needs no key. Scaffolding and review call the model provider you pick here with your own API key (free tiers: Gemini at ai.google.dev, OpenRouter :free models). The key is saved only in this browser, on this computer, so you paste it once; it is sent nowhere except the provider you chose. On a shared computer, press forget when you are done.

What the labels mean

starts here: This sugya begins on the daf you scanned.
carries in: The sugya began on an earlier amud and continues onto this daf. The opening words shown are from where it really begins, back there, and the scan and text links take you to that amud.
runs past: The sugya does not finish on this daf; it continues onto the next amud. Scaffold brings the whole sugya, past the end of the daf.
canonical: The start and end of the sugya come from the source library's recorded passage divisions, the same division every time for everyone. No AI draws these boundaries.
The signs on the moves: Road language: a green circle opens a statement; an amber ? asks (a question or inquiry); a warning triangle is an objection; a green ! answers (answer or resolution); a green up arrow is a proof; a red no-entry sign is a rejection (the proof or answer is blocked); opposing arrows are a machlokes; a circle with a dash is a limitation; a red stop sign is the conclusion. A framed label is a tannaic source (Mishnah or beraisa). Moves that respond to a challenge sit one step inward under it.
Translation under the Gemara: English is the William Davidson Edition (the Koren Talmud Bavli by Rabbi Adin Steinsaltz); its bold words are the literal translation and the plain words are its explanation. עברית is the same edition’s Hebrew Steinsaltz. The Kohen, Mincha switch changes only the English wording, and the credit line then says it was adapted.
omission? / misstatement?: Flags raised by the reviewing model after it reads each summary against the Gemara's own words: omission means the summary may have skipped a claim the text makes; misstatement means the summary may say something the text does not. They are questions for you to judge, not rulings.
check: segments not covered: The scaffolding model's moves left part of the sugya unaccounted for; the scaffold is incomplete there.
