Scenyo Game Master
Scenario: Stranded on Mars
What is Scenyo?
Scenyo is an AI-powered interactive scenario game where you pick any setting — survival, fantasy, sci-fi, historical, anything — and an AI Game Master dynamically asks questions, tracks your stats, and generates a unique story based on your choices. Every playthrough is different. No pre-written paths. Just step in.
How it works
Three steps from idea to story
No tutorials, no login walls, no 50-page rulebook. You step in, the Game Master does the rest.
1
Pick Your World
Choose from 50+ scenarios at launch — or write your own premise in one line.
2
Answer the AI
The Game Master asks questions. You respond however you want, in plain English.
3
Live the Story
Your choices shape consequences, stats, and the ending. Replay for a different run.
A few launch scenarios
What kind of story do you want tonight?
Each scenario starts a completely new world. Your choices — not a pre-written script — decide where it goes.
Medieval Dungeon Escape
Chained in a cell with a rusted nail, a whispered rumor, and one hour before the executioner arrives.
1920s Detective
A socialite is dead. Three witnesses are lying. Your trench coat is wet, and the chief wants a name by dawn.
Lost in the Amazon
Your plane crashed two days ago. The river goes north. Or maybe south. And something is watching the treeline.
Royal Court Intrigue
The queen is dying. Five heirs want the crown. You are the one they all underestimate — for now.
Post-Apocalyptic Survivor
Day 412 after the collapse. You have a map, a radio, and half a can of beans. Someone is broadcasting again.
+ 44 more scenarios at launch. Plus, create your own.
Why Scenyo
Why Scenyo is different from every other AI game
Most AI games loop the same 3 endings. Scenyo actually remembers what you did on turn one.
Infinite replayability
No pre-scripted branches. The story is rebuilt every time you play, even in the same scenario.
Any genre you want
Survival, romance, horror, sci-fi, business, historical, silly — the Game Master adapts its tone to the world you pick.
Remembers everything
Consistent characters, stats, and consequences across long sessions. The name you gave that stranger on turn 2 still matters on turn 40.

What testers are saying
Early runs, honest reactions
"I picked a 1920s detective scenario on a whim. Twenty minutes later the AI had me interrogating a suspect I had invented myself. Genuinely the most fun I've had in a browser."
M
Maya R.
Early tester
"Every run is different. I tried the Mars scenario three times and got three completely different endings. The stat-tracking keeps it tense."
D
Dev P.
Early tester
"I wrote my own scenario — a bakery running out of flour during a snowstorm — and the AI took it somewhere I never would have guessed. Brilliant."
