Explain Earth to an Alien
Explain a human custom (birthday cake on fire, handshakes, tipping) so a literal-minded alien really gets it.
Try it free →Practice mode · Character Scenes
Improv works best with a partner who commits: accept the premise, build on what the other character just said (“yes, and”), and keep pushing toward a goal instead of stalling. A one-on-one scene with a character who reacts to every word lets you practice that alone, any time. Pick a ready-made scene or set up your own (a character, a setting, a goal, a tone and a card), then talk until you win or lose the scene.

What happens
Real lines from a test session
“Fascinating. So the hand gesture says, I could have hurt you, but I choose not to. And if I squeeze too hard, the trust evaporates.”
“The weather in Phe-nix? You stand in my throne room, waste my time, and now you ask me about the temperature of a place I have never heard of? Guards! No, wait.”
“Lost your group a week ago. That's a long time to survive alone. What happened to them?”
From a test session of this practice in the app, lightly trimmed. Your session goes its own way: the character reacts to what you say.

Common mistakes
Weak: “I don't know, I guess I just want to go.”
Better: “I want to go because I can help you win. Give me one task and watch.”
A clear reason gives the character something to answer.
Weak: “You're wrong and you're not listening to me.”
Better: “I hear you. Let me try that a different way so it makes sense.”
Staying calm keeps the scene moving instead of ending it.
Weak: “That's not fair! You have to let me in!”
Better: “What would it take for you to open the door? I can do that.”
Asking a question puts you back in control of the scene.
Weak: “Um, so, like, I was wondering if maybe...”
Better: “Here is my offer: one gold coin now, and I leave you alone.”
Short, clear lines are easier for the character to react to.
