Sender: Unknown Signal

Guide strangers through real crises with AI-powered text conversations. Your choices shape every outcome.

Your phone buzzes. A stranger needs your help.

Welcome to Sender, the AI-powered narrative game where every text message is a matter of life, choices, and consequences.

You are the unseen guide. On the other end of the screen: a survivor stranded on a remote island, a whistleblower inside a corrupt pharmaceutical company, a witness in hiding, a startup employee uncovering a scam, and more. Each person only has you. What you say — and how you say it — shapes their fate.

STORIES THAT REACT TO YOU Sender's conversations are powered by real AI. Characters respond dynamically to your tone, strategy, and choices. There is no single right answer. Guide gently, negotiate hard, call the bluff — the story bends to your decisions.
