Upload your indie TTRPG system. Watch an AI run it — enforcing mechanics, tracking state, narrating outcomes — autonomously, 24/7, solo.
You've built something. A ruleset with weight and intention. Dice mechanics that mean something. Systems that don't play like anyone else's. But every AI tool on the market locks you into their world, their rules, their genre.
The AI Dungeon Master category is a $1.2B+ market growing at 30% annually — and zero products serve indie TTRPG creators. 30,000+ games on itch.io. Zero AI tooling.
Three things AI Dungeon Masters do. We do them for YOUR system.
Upload your dice system, stat blocks, combat mechanics. Our AI reads your rules — not generic ones — and enforces them in every encounter.
NPCs that remember your character across 40 sessions. Locations that persist. Faction grudges that compound. No drift, no resets, no retcon.
Start a session before bed. Wake up to a campaign that moved without you. NPCs acted, encounters resolved, the world state updated. Your game never stops.
dice: 1d6 + stat mod vs DC stats: Body, Finesse, Mind, Presence death: 0 HP = dying, -1 per round fumble: roll 1 on attack = crit fail xp: discover > defeat rest: 1 heal die per shelter // Paste into SagaForge. AI reads it. // Starts running your game.
No D&D. No generic fantasy. Upload the system you built — OSR d6, JRPG 2d6, solo oracle, hexcrawl, whatever you've created — and our AI learns it and runs it. Dice, combat, conditions, advancement. All of it.
For indie creators: this is a playtest environment that runs while you sleep. Watch your rules actually work on a real player. Find the gaps. See what your rules make possible that you didn't design.
itch.io has 30,000+ indie TTRPG titles. No AI tool supports a single one of them.
Run it. Play it. Let it surprise you.
