Single-player story games, alive with AI
Stories with a will of their own.
Weave a world — its quests, its cast, its maps — and let it loose. Every character remembers, wants and schemes, and every scene is drawn and voiced as you play.
Open-source engine · Runs on your own GPU · No per-message fees
Pick a genre and the whole story changes clothes
Act II · The North Crossing
The Ferry Landing
The landing smells of tar and river weed. Marren is coiling rope and doesn’t look up when you arrive.
Marren
“You’re the third stranger asking about the north crossing this week. The other two paid in silver.”
Marren remembers: you lied to her brother in Act I.
- Offer her silver
- Ask what the other two wanted
- Challenge her to Ferryman’s Dice
Chapter 3 · Kepler Relay
Dock 7
The relay hums through the deck plates. A maintenance drone stops mid-weld and scans you twice.
VESNA-9
“Your transit code was issued eleven minutes after the captain died. Please explain that.”
VESNA-9 logged: you hesitated when asked your name.
- Show the captain’s last message
- Call it a clerical error
- Slice into the dock terminal
Night Two · The Ashby House
The Nursery
The music box is playing again. You wound it down an hour ago.
Mrs. Ashby
“She only plays for people she likes. You should be flattered. Or careful.”
Mrs. Ashby remembers: you lit the lantern without asking.
- Close the music box
- Ask who “she” is
- Leave the house now
Case file 12 · Thursday, 2 a.m.
The Blue Room
The singer finishes her set to an empty room. Rain keeps time on the windows.
Lou Vance
“I sing for the people who pay me, detective. Tonight nobody paid me to remember.”
Lou remembers: you were seen with the man from the docks.
- Slide a twenty across the bar
- Mention her brother Eddie
- Show her the photograph
Day 41 · Route 9 outpost
The Water Gate
The outpost gate is welded shut. Someone has painted NO MORE MOUTHS across it in red.
Rook
“We’ve got water for twelve. You make thirteen. Convince me you’re worth a share.”
Rook remembers: you shared your canteen on the road.
- Trade the radio parts
- Offer to scout the dead zone
- Show your medic badge
What makes a world feel alive
Characters who remember. Worlds that react.
Kin with memory
Characters keep track of what you said and did, and act on it chapters later.
Scenes, drawn as you play
Places, people and moments illustrated as the story unfolds, in the style of its genre.
Every kin has a voice
Spoken dialogue, with a distinct voice for each character.
Shareable activities
Riddles, dice, duels and card games inside the story — share them with friends.
Your hardware, your stories
Runs locally on your own GPU. No per-message fees, and your worlds stay on your machine.
Any genre, built for RPGs
Fantasy quests, mysteries, sci-fi, horror — whatever you weave.
Write it. Play it. Share it.
One app, two ways in. Weavers build worlds; players step inside them. Most people end up doing both.
For weavers
Build a world, not a script
- Create the cast — personalities, goals, secrets, who they love and who they owe.
- Lay out quests, maps and factions.
- Set the tone and the rules: genre, pacing, what the kin may and may not do.
- Publish your world as a Ravel anyone can play.
For players
Step into a world that reacts
- Talk to anyone, in your own words.
- Characters remember what you did — and tell each other.
- Scenes and voices are generated as the story moves.
- Start from a published Ravel, or weave your own.
Three steps, then it runs itself
How it works
1
Weave
Write a Ravel: the setting, the kin, the quests, the map. As detailed or as loose as you like.
2
Publish
Share your Ravel as a template. Every player gets their own run of your story.
3
Live
Gremlin Engine runs the kin — memory, goals, relationships. No two runs end the same way.
The gremlin keeps the gears turning.
