The letter you never sent.

UnsaidX exists for the sentences you've rehearsed in your head for months, sometimes years. The ones that never made it past your teeth.

You write to someone you already know. They open it. They read it once. Then it dissolves — from their screen, from our servers, from everywhere. No screenshots that mean anything. No going back.

You stay anonymous. They never know it's you. That is the whole point. Distance is what makes the truth possible.
