The world remembers
Every choice persists. Every promise sticks. NPCs remember who you helped and who you crossed. Travel for a season. Return to a town shaped by your actions. And by the events that came after.
Branching Skies
Stories that remember you.
A mobile choose your own adventure in a hand-built world that remembers every choice you make.
Available soon
The world is waiting. Will you save it or let it burn?
Branching Skies is interactive fiction in hand-built worlds. Create a character. Step into Syrinway, a fantasy realm with named places, real NPCs, and history that started before you arrived. The narrator describes the world. You decide what your character does. The world remembers.
Memory you can see.
Your campaign shapes and turns as Algus remembers choices you make, NPCs you befriend, brigands you betray, and tavern-keeper's daughters you choose to love.
Key features
Hand-built, not generated
Named places. Real NPCs. History that started before you arrived. We built the world. You and our AI “Narrators” bring it to life.
Burn it down or build it up
Save the kingdom. Or watch it fall. Help the merchant. Or rob him blind. Every choice ripples outward. The world responds to who you choose to be.
Help us shape this world.
The first closed beta is next on our build plan. Founders get the Founder’s Beta Badge and the first say in what Branching Skies becomes.

Frequently asked
Answers, before you ask.
Does the AI remember my choices across sessions?
Yes! Help Anelise when she needs it, and she still greets you warmly when you walk into the inn days later. The game keeps track of the people you’ve met and how they feel about you, so each session picks up where the last one ended.
What happens when the AI gets confused or forgets something?
AI can drift, even the good ones, so we built around it. The game keeps its own record of the people you’ve met and the things you carry, and Algus tells the story from that record, so the big things stay right. If the flavor ever feels off, tell us. That’s what beta testers are for!
Do my choices actually matter, or is the AI just guessing?
Yes. Steal in front of a witness in Derandil and word gets around, because the town remembers your face. Be kind to the baker and he remembers that too. The AI tells the story, and the game keeps track of what mattered.
Will my character’s reputation persist if I stop playing for a few weeks?
Yes. Step away for a month and the world waits for you. The people who trusted you still trust you, and the town still remembers what you did there, because the game keeps that record itself instead of leaving it to the AI’s memory.
Is Branching Skies an AI companion or chatbot?
No. Branching Skies is a story you play, not a chat app. You step into a world we built by hand and decide what your character does, while the narrator tells you what happens. The people you meet have lives that carry on without you. The narrator and every character are AI, telling a world we built by hand.
Is this an AI D&D game?
No. We built our own system, rooted in tabletop tradition and stripped down to what matters. Your hero has six stats, and every roll is one d20 read on four tiers from disaster to triumph, so there is nothing to memorize and no rulebook to stop the action. You grow from level 1 to 10 through the choices you make.
How is this different from AI Dungeon?
AI Dungeon calls itself "an infinitely generated text adventure." We went the other way. Syrinway is hand-built, with named places and people whose history started long before you arrived, and the AI tells the story from inside that world instead of inventing it as you go. What becomes of it from there is up to you.
Can I play this without a group?
Yes. The whole game is built for one player, so there is no group to gather and no DM to schedule around. Play for five minutes on a break or for hours at a stretch, and the story will be waiting each time you come back.
Who is Branching Skies for?
Adults. You must be 18 or older to play. We still filter out explicit content. Romance can happen, but it fades to black. Violence stays at fantasy-adventure levels. It is for players who want a real story without things getting gross.
When can I play it, and how do I get on the beta list?
Coming soon. Sign up and we’ll email you when the closed beta opens. You’ll play first and help us shape the game before it ships.
Is it free, and what will it cost?
Yes. Free to start. Unlimited play, with ads. Paid tiers unlock richer writing and drop the ads. They start at $4.99 a week in most regions. You get a free trial when you sign up. Cancel anytime. No surprise charges. We want everyone to be able to play, so we aren’t hiding the game behind a paywall. Ads just keep the lights on!
Are my stories private?
Yes. Your stories are yours. Machines screen every turn for safety; a person reads a turn only when it is flagged, when you ask us for help with it, or when you agreed to playtest, and every read is logged. Encrypted at rest. Delete anytime. We don’t sell your data. We don’t train AI models on your stories. The AI companies that write and screen the story do see your words; the privacy policy names them.
