    What Virvyxn keeps track of

    At any point in your story, three questions.

    01

    What is true?

    Facts, events and world rules as your manuscript establishes them, including the ones that change.

    02

    Who knows it, and when?

    What each character knows, believes, suspects or was told, chapter by chapter. The reader too.

    03

    Where's the proof?

    Every claim links to the passage that supports it. One click and you're there.

    An AI that writes gives you another draft. Virvyxn understands the one you have.

    Conflicts & review

    The established reading is kept.You decide what changes.

    When a passage contradicts what the Story Model already holds, Virvyxn doesn’t pick a winner. The established state stays, and a review item opens with both readings and both sets of evidence.

    The same conflict found on ten runs is one item, not ten. Your queue stays worth reading.

    Possible knowledge conflictWAITING ON YOUEXAMPLE

    In Chapter 19 Aélis speaks of Daniel as being from another century. The established state says she still believes he is an explorer.

    BOTH READINGS
    CH. 14 ¶ 6 · ESTABLISHED: BELIEVES“You speak like the men from the eastern coast. All explorers do.”
    CH. 19 ¶ 12 · NEW READING“You don’t belong to this century, Daniel. You never did.”
    How do you want to settle it?
    Provenance

    Evidence, not vibes.

    Nothing the model reads enters the Story Model without a passage behind it. Every claim keeps the exact words it was read from, the scene it came from, and the run, model and prompt that read it. A claim that can’t cite your text is rejected, not kept at low confidence.

    Evidence is anchored to paragraphs, not character positions, so it survives your edits. Delete the paragraph and the quote isn’t lost: it goes to your review queue.

    The language model reads your story. Your manuscript remains the record.
