Read the Fathers, the councils and the Scriptures; mark what matters; link your own sentences to the passages behind them; and write. One place, working offline, with your library on your own disk.
Free to use. No AI anywhere in it, no ads, and nothing you read is sent anywhere. It asks you to sign in once — your library belongs to the account, so it follows you to another computer — and works offline from then on.
The desk
Sources on the left, your own writing on the right, both open at once. Up to five source tabs, each holding its place, and a pinned Bible slot whose translation you swap without losing where you were — across the Psalm, Joel and Malachi renumberings included.
Quote a passage into your writing and the link is real: hover for the text, click for the surrounding context, and jump the reader to the exact block. Every reference is two-way — a passage you have written about is marked in the source.
"Romans 5:12" is recognised wherever it appears, in the sources and in your own prose, and opens whichever translation is in the slot. Verses carry the OpenBible.info cross-reference compilation — about 340,000 links, remapped to Vulgate numbering.
A question is a document allowed to stay open for years. A claim is a proposition with passages attached to it, each marked as supporting, contradicting or qualifying it. Neither is inferred; both are things you state.
A book over a season, a source straight through, or a syllabus you already keep in a spreadsheet — dates, themes and all. A reading that names works you have not got yet is kept as written and starts opening the day you import them.
Import EPUB, PDF, Word, saved web pages, Markdown or plain text. Texts under copyright are not bundled, so you bring your own copy. Search runs over the sources, your annotations and your writing at once.
An open feed you post to under your own name and read by following people, and private spaces — a classroom, a parish, a study circle — where what is said stays inside. Nothing crosses between them.
Markdown, standalone HTML, Word with real footnotes, or print. Each work is cited by its own convention — ST I-II, q. 110, a. 1; Conf. III; Trent, Sess. VI, can. 9 — with a generated bibliography.
