    Why Unmark

    What your eyes can't see.

    Every copy-paste from an AI can carry stowaways. Unmark finds them all.

    01

    Ghost characters

    Invisible on screen, very real to a machine. They sign your text without you knowing.

    Wiped

    02

    Fake spaces

    They look like normal spaces. Yet they give away where your text came from.

    Replaced

    03

    Hidden signals

    Tucked into the formatting, they slip under every radar. Except ours.

    Removed

    Your words. Nothing else.

    Unmark wipes what you can't see and keeps everything else: your emoji, your accents, your layout. No account. No server. No trace.
