An AI-free core
The retrieval and attribution core runs with no language model in the path. pericopa references Scripture; it never produces it. No paraphrase, no synthesis, no generated text standing between you and the source.
Reference, not generation
Know exactly where a Scripture reference comes from.
pericopa is the trust layer for Bible study: it surfaces where a passage lives, which tradition's canon holds it, and where editions diverge — every reference traceable to a named source.
The thesis
Trust comes from attribution, not assertion.
Most tools answer a Bible question by handing you a sentence and asking you to trust the tool. pericopa does the opposite: it hands you the citation. Each reference carries its source, its tradition, and its points of divergence, so you can follow it back to the record yourself instead of taking a single rendering on faith.
How the trust holds.
Doctrine as a first-class model
Canon, versification, and tradition are structural, not footnotes. pericopa is built on a schema-validated doctrine model, so a reference always carries the tradition it belongs to — never flattened into one default Bible.
Every reference, traceable
A citation is only as good as the path back to its source. pericopa keeps that path intact end to end, so any reference it surfaces can be followed to the named edition it came from.
The apparatus
Three lenses over the record — each an identifier, never a ruling.
pericopa borrows the discipline of a critical apparatus. Its marks name what you are looking at; they do not grade it. Color is an identifier here, never a judgement.
Edition & text
Marks where editions of a passage diverge — wording, versification, what each one includes. A reading lens over the textual record, not a position on it.
