Other AI game masters can fudge the dice. This one can't.
A real D&D 5e or Pathfinder 2e campaign you can play solo, any hour. A deterministic engine rolls every die and enforces every rule, so the AI narrates the story but can never fudge an outcome. No credits, no meter. Play the whole month flat, or bring your own AI and own it for life. Fully live, solo-built, tuned daily.
A note on focus: our heart is in D&D 5e right now - that is where every new class, spell, and bit of polish lands first, daily. Pathfinder 2e is fully playable today; it gets its own dedicated wave once the table fills.
Never played a tabletop RPG? Perfect.
No rulebook, no math, no group, no experience needed. You just say what you want to do, in plain words - the engine rolls the dice and runs the rules, and the AI teaches you as you play. Your first hero takes about two minutes.

Four disciplines. Daily work orders. Your name on your masterworks.
Learn patterns from guild masters, roll the weave on every craft, gamble a masterpiece on a Fraying Needle - and sell at prices that drift with the world's moods. All server-enforced. Never pay-to-win.
Bring your party. One Game Master serves you all.
Up to five players share one living campaign - tank, healer and three more chairs at the same table. Included with the subscription: no party fee, no guest pass arithmetic.
The world keeps moving when you look away.
Prices drift, feuds sharpen, rumours travel, and the night decides what hunts in the dark. Come back tomorrow to a different town - and a ledger that can prove every change.
The art is AI. On purpose - for now.
Most studios would hide this. We won't: the characters and scenes you see are AI placeholders, and that was a deliberate call. The hard part - the part no one else has built - is underneath: a cheat-proof engine that rolls every die in the open, and an AI Game Master that tells the story but can never fudge the outcome. We spent the effort there first, shipped it, and handed it to you in placeholder skin - because we'd rather learn you love the idea before we spend a fortune dressing it up.
If enough of you do, the next thing we fund is a real artist - hand-crafted characters, scenes, and an interface worthy of the engine beneath them. Chip in what you like. You're not buying finished art; you're funding the upgrade - and backing a kind of game that has not existed before.
Fund the artist →Every contribution funds a real artist for LoomMaster, under The World Table - hand-made characters, scenes, and interface. Secure checkout via PayPal; the engine is already yours to play, free to start, no card needed.

NPCs that actually remember you.
Spare the goblin king in session 3 and his envoy finds you in session 7. The merchant recalls your last haggle; the faction tracks every favor and slight. That is real world-graph state saved to disk - not a context window that quietly forgets after a couple hundred messages.
Honest dice the AI can't fudge.
Every roll, DC, and hit-point swing runs on a deterministic engine with seeded dice - never the language model's imagination. The AI narrates what happened; it never decides whether you hit. No quiet number-fudging, no easy-power-fantasy drift, and a tamper-evident chain means a result can't be rewritten after the fact. Pathfinder 2e shipped 2026-05-28 - same deterministic engine, full Core ruleset (degree of success, three-action economy, focus spells).
No per-message billing. Play freely.
No token meter, no per-message charge, no out-of-credits wall, no ads. Run a six-hour Saturday session for the same flat $29.99/mo. A generous monthly fair-use ceiling exists only to stop industrial abuse - bots and runaway loops - and a normal solo player, even a heavy one, never comes close.
Your character, your call. Always.
The Loom narrates the world and plays every NPC - but it will never put words, thoughts, or actions in your character's mouth. That boundary is enforced in the Director routing layer, not just politely requested in a prompt. Your character is yours, no exceptions.
Proof, not a promise
Every roll, DC, and hit-point swing is decided by a seeded, deterministic engine - never the language model. The AI narrates what happened; it never decides whether you hit. And every result is sealed under HMAC-SHA-256 into a tamper-evident chain, so a number can't be quietly rewritten after the fact. You don't have to take our word for it - you can audit it.
Bring your whole group to one table
Co-op party play is live for both Pathfinder 2e and D&D 5e: several players share one AI Director - a real table where the Loom runs the game, rolls every die, and enforces every rule. (One ruleset per table: a party is all-5e or all-PF2e.)
This is a deep game, not a demo
A huge content wave just landed - new endgame regions, dozens of new foes that actually fight you, real build choices, and a world that keeps changing while you play. The kind of depth that turns a try into a campaign.
40+ new foes, including multi-phase region bosses.
Themed elites with signature telegraphs and real tactics - they shove you off high ground, drag you into a hazard, and coordinate across a pack. Boss fights shift through phases. The engine runs all of it; the AI Game Master narrates it and can never soften a hit.
Two new endgame regions - a drowned reliquary and a stormspire.
The Tidewrack Reliquary, a drowned court of the dead sunk under black tide-water, and the Stormspire Heights, a storm-wracked sky-fortress crowned by a riven thunderhead. Each holds its own Sealhouse Witnesses to confront - and a Verdict sealed into the chain when you win.
Subclasses, feats, and a post-cap Ascendancy board.
Real build choices the engine actually enforces - subclass features (Eldritch Knight, Veilstalker, the arcane traditions and more), a grounded feat system, fresh cantrips, and a post-cap Ascendancy board that keeps your hero growing after the level cap. Every node folds into the same honest math as a rolled affix.
A living realm and an endgame that never runs dry.
Faction blocs rise and feud, NPCs live out their own arcs, and omens stir across the regions whether you are there or not. At the cap, the Sealhouse scales on forever with a fresh paragon climb - and a weekly Sealed Ladder ranks the whole world on proof, not bragging.
Every scene, rendered
From the Brassgate market to a drowned circle under the marsh - the Loom paints the place you're standing in, scene by scene, as the story moves.
A few of the places the Loom has painted. The world generates more as you explore it.
The full Loom, live now
It is all here and playing now - D&D 5e and the full Pathfinder 2e Remaster on one honest, deterministic engine, across all 12 classes. Plus async play-by-post, custom homebrew, campaign sharing with a live spectator view, a rules-aware Director, a living shared world, an optional tactical grid, and opt-in co-op party multiplayer. Playable now.
D&D 5e and the full Pathfinder 2e Remaster, on one engine.
Run a D&D 5e campaign or the full Pathfinder 2e Remaster across all 12 classes - the same honest engine, real dice, real DCs, the full Director toolset on both. Behind both: a deep catalog the engine controls - more than 500 monsters across both rulesets, high-level spells (meteor swarm, time stop, wish), hazards, ancestries, and classes. The Director picks from it, never invents.
Roll a character →Bring friends or AI companions into one world.
One shared, remembering campaign: multi-character parties with turn order on the Judge tier, host invites, and session resume that keeps initiative, conditions, and hero points. Roll with AI companions and familiars too. The first step from a solo table toward the wider Loom.
Start a party →The dice, the rules, and your agency - enforced in code.
A seeded engine rolls every die server-side, so neither the AI nor anyone else can fudge a result. 5e and PF2e rules run deterministically, recovery checks are server-rolled, and the Director can never act for your character. Integrity is the product, not a setting.
How it stays honest →Play through any MCP client - yours for $49.99 once.
Already pay for an AI? Connect any MCP-capable client (Claude Desktop, Claude Code, and more) over MCP. Your AI narrates and covers its own usage; our server runs only the cheat-proof engine. One-time $49.99, no subscription - the same engine and content as the web tier. Solo only - co-op party play is on the web tier.
Connect your AI →Grease the floor. Throw a torch. Shove them into the fire.
Combat is a chain you set up, not a number you trade. Lay elemental surfaces - burning ground, a slick of oil, a conductive flood - then ignite, douse, or electrify them; shove a foe one band back or onto a hazard; take the high ground for advantage on your shots; spend the Loom's Favor to bend a roll. Every die in the chain is rolled by the engine and the AI only narrates what it resolved - so the most cinematic moment in the fight is also the one it provably cannot fudge.
Step to the table →See every blow land - and press H the moment you want to know more.
Every spell, strike, and skill shows a small icon the instant it resolves; foes wear their conditions - Frightened, Prone, Poisoned - right on the initiative bar, and a bloodied enemy says so. New to all of it? Press H for a searchable in-game Codex on every class, race, background, condition, and system in plain words - or just ask the Loom in chat and it guides you like a patient table-mate, no wiki tab required. The depth is real; the on-ramp is gentle.
Open the table →The whole game explained, in plain words.
The same in-game knowledge base, now public on the web. Every class, race, background, condition, spell, and system - written plainly and searchable, with no login. Skim it before you ever roll a die, and start your first hero already knowing the table.

Why not just use a free AI as your Game Master?
A free chatbot will happily play Game Master. It will also fudge the dice, forget your world between chats, invent rules when the story needs them, and narrate your own character's actions for you. LoomMaster makes all four impossible by design.
- Rolls dice in its head - and nudges them so you win
- Forgets your world once the chat scrolls away
- Invents and bends rules to keep the story moving
- Happily writes your character's actions for you
- A seeded engine rolls every die - it can't fudge, and neither can you
- A real database remembers NPCs, factions, and choices, run to run
- D&D 5e and Pathfinder 2e rules enforced by a deterministic engine, not vibes
- You always hold your own character - agency enforced in code
Where LoomMaster fits
There are many ways to tell a story with AI. Here is the honest map - and the one thing LoomMaster is built to do better than anything else.
A real, rules-true D&D 5e or Pathfinder 2e campaign you can play solo, on demand, any hour - no group, no scheduling, no Game Master to wrangle. The engine rolls every die and applies the rules itself: the AI narrates the world, it never decides whether you hit. And the world and its people remember you, run to run.
Bring the AI you already use. Connect TheWorldTable to any MCP-capable client (Claude Desktop and others) as an MCP server: your AI narrates the adventure and covers its own usage, while our server runs only the parts that must be cheat-proof - it rolls every die with a seeded generator, enforces the 5e and Pathfinder 2e rules, records each result in a tamper-evident chain, and remembers your world run to run. $49.99 one-time - pay once, own it for life, no subscription, ever - you bring the AI, so there is nothing recurring for us to bill. The web tier charges every month; this you pay once and own. Solo only - co-op party play is a web-tier mode.
Questions, answered
Is it really unlimited?
Can the AI cheat the dice?
What happens after the free trial?
Do I need my own AI?
Are there other AI Game Masters that can't fudge the dice?
Is "unlimited" really unlimited - no energy bar, no daily turn cap, no dumber model?
One engine, two products. The same Director-routed Trinity behind LoomMaster also powers Mythcore: Omniveil, our AI-driven MMORPG in open pre-alpha. The persistent-memory tech that lets your Game Master remember a campaign is the exact tech that lets a living MMORPG world remember every player who ever passed through it.
And the deterministic core is now published source-available - one Rust core that runs byte-identically in TypeScript, Python, and Rust, on npm, PyPI, and crates.io. It cleared an external security and determinism audit with 4,270 tests green. Cross-language byte-parity is what makes the dice honest: the engine owns the math, the AI only narrates.
