Play a sci-fi RPG with an AI Game Master.
Ships, crews, colonies and the long dark between them. An AI Game Master runs the setting, plays every crewmate and official, and keeps the map and the politics straight across a whole campaign. Free to start.
Or jump straight in, no setup:
Free to play in your browser and on Android. The full memory system is on every plan, including free.
Science fiction campaigns fall apart on continuity. Distances change, a colony moves, the crewmate who died last session walks back in. Auferet is an AI Game Master built to hold a setting still: named characters, places and events go into libraries it reads every turn, and the map keeps fixed coordinates so a three-day journey stays a three-day journey.
Describe a character and a situation in a sentence, and the Game Master opens the scene. You play in plain language. No sheet to build first, no group to schedule.
Fourteen sessions in
The star map still lines up
Session fourteen
> I set course for Tarsis Station to sell the cargo.
Tarsis is nine days out at your current burn, and you are still flagged there from the quarantine you broke in the spring. Nakamura would take the cargo without asking questions, but Nakamura is on the far side of the belt and your reactor is due for the maintenance you keep deferring.
The distance, the old quarantine violation, Nakamura and the deferred maintenance are all on file from earlier sessions. The setting pushes back with its own history instead of improvising a fresh one.
What it keeps track of
A galaxy that stays where you left it
A map that holds still
Stations, worlds and routes get fixed positions, so distances and travel times stay consistent all campaign.
A crew that persists
Every named crewmate, official and rival is stored with personality and history, and plays consistently whenever they return.
Hard or loose
Rigorous hard science fiction, space opera, or anything between. Tell it the tone and it holds it.
Ship and gear tracking
Cargo, fuel, repairs and conditions persist, so deferred maintenance is a real decision.
Your own universe
Upload your setting as a PDF or text file and the Game Master treats it as canon.
Free to start
Free to start, and the full memory system is on every plan including free.

Say who is flying
A captain, a stowaway, a courier hauling something they were told not to open. One sentence, or tap a scenario above.
Describe it, do not menu it
Say what you do. The Game Master runs the ship, the crew, the port authority and the rolls.
Pick the route back up later
Your route, your crew and every deal you struck are saved. The campaign waits.
Questions
Running a space campaign, answered
Do I need a sci-fi rules system?
No. Describe a character in one line and play in plain words. For full mechanics, use a system mode or build your own rules in a custom game mode.
Will the setting stay consistent?
That is what it is built for. Places go on a world map with fixed coordinates and people go in a character library, both read back every turn.
Can I run a whole campaign?
Yes. Events from early sessions stay available to the Game Master hundreds of turns later, so long arcs pay off instead of resetting.
Can I bring my own universe?
Yes. Upload your worldbook or notes and it becomes the canon the Game Master plays inside.
Is it free?
Sign in to play free, with 10 credits to claim daily. The memory system is the same on every plan.
Can I play a sci-fi RPG solo?
Yes. The AI runs the game master seat, so it narrates the ship, plays the crew and the port authority, and answers whatever you try. Solo is the default and there is no group to assemble. You can bring a friend into the same campaign later and take turns.
What breaks a long sci-fi campaign?
Continuity. Space games accumulate names fast: ships, stations, factions, a crew with their own history, a route you already burned. A game running on recent context only will start contradicting its own star map a few hours in. Keeping that straight over a long campaign is the thing worth checking before you invest in a setting.
Can I run a whole crew instead of one character?
Yes. Describe the crew and the game master plays them as persistent characters with their own voices rather than re-rolling them each scene. They remember what you did on the last job, which is what makes a crew feel like a crew instead of a list of names.
Does it do hard sci-fi or space opera?
Either, because the tone follows your description rather than a fixed setting. Ask for cold, slow, physics-respecting travel and it holds that. Ask for jump drives and a galactic senate and it holds that instead. The one thing to state early is the tech level, since that is what everything else hangs off.
Is there a free sci-fi text adventure online?
Yes. This one runs in the browser, no download and no card, and a scene starts from a single sentence. The free tier claims 10 credits a day and gets the same memory system as the paid plans.
Can I play in an existing universe I have notes for?
You can upload your own worldbook, lorebook or campaign notes as a PDF or text file, and the game master treats that as canon for the campaign. That matters for sci-fi in particular, because a game that cannot read your setting will invent its own version of your tech and contradict you by hour three.
Can I play it on my phone?
Yes. It runs in a mobile browser with nothing to install, and there is an Android app as an option. The world lives in the browser you play in, so export it if you want it on a second device.
Take the job. Read the cargo manifest later.
Ports, routes and crew stay fixed all campaign, so the galaxy still makes sense in hour ten. Free to start, in your browser.
