    real-time
    co-write.

    Write in the same scene at the same time. No merge conflicts. No save button. Cursors, presence, threaded comments — all the room, none of the noise.

    Presence, not pings

    see what the room is doing · no email · no chat app

    Every writer in the document is a colored cursor with a name. Hover their initial in the gutter and you jump to where they are. The presence chip in the corner is the only chat — and it disappears the moment you start typing.

    Anchored to the text, not the page.

    When a line moves, its comments move with it. When the page breaks shift, threads don't orphan. When a producer asks "is this still open?" the answer is on the line, not in an inbox.

    resolution rules
    01Author of the comment can resolve.
    02Any producer can resolve any thread.
    03Resolved threads collapse but never delete.
    04Re-open by replying — the anchor returns.

    No merge button. No conflict.

    works offline · syncs when you reconnect · nobody loses a line

    Three writers, one scene, one airplane Wi-Fi outage. Arqo saves your changes and updates your collaborators with your input as soon as you're back online.

    offline windowWrite on a plane for six hours. Reconnect and your scene catches up in a second.
    no overwritesWhen two writers touch the same line, both edits land. Nobody’s words disappear.
    private by defaultYour script stays encrypted between collaborators. The relay only sees scrambled bytes.
    version historyEvery change is timestamped and attributed. Roll back to any moment — yours or theirs.

    Every minute is a snapshot. The last 30 days are restorable on Pro; 18 months on Studio. Deleted scenes have a paper trail. The room remembers.
