AI game master
An AI game master for your own setting
You've written a world. Worldtable lets an AI run it for your players without losing hold of it: your map, peoples and rules are held by the engine, and your lore is handed to the storyteller every scene.
- Bring your world
- Paste lore section by section, or import lore books, PDFs, Word files and rulebooks (up to 60 MB a file)
- Rules
- About twenty rules picked in plain words and held by code, or a rule system such as Classic d20 (in beta)
- Game master
- An AI storyteller narrates and plays every character; the engine decides fights, travel and money
- Before anyone plays
- Ask your world any question; a review lists contradictions, gaps and loose ends
- Players
- Invite them with a link; each pays for their own turns, or plays free on your own AI key
- Your model
- OpenRouter, any OpenAI-compatible provider, or your own local model through a tunnel
Updated October 2026
Bring the world you've already written
- Paste it in. Section by section: peoples, magic, powers, the cast, places. Every text box has helpers that tidy what you paste or flesh it out, with an undo.
- Import it. The Import & Export tab reads SillyTavern, Chub, NovelAI, Agnai and KoboldAI lore books with no AI, and books (PDF, Word, Markdown, text or saved web pages, up to six at once and about 600 dense pages) into your world. A world holds up to 2,000 lore entries.
- Import your rules. A rulebook's abilities, creatures, gear, conditions and classes come in as working rules: up to 400 abilities, 200 creatures, 300 pieces of gear, 60 conditions and 40 classes from one import. Only bring in books you have the right to use.
How importing works, and what it costs: Import & Export.
Rules the game master can't bend
Every world has about twenty rules, each picked in words (whether heroes die for good, how dangerous the world gets, how fast heroes grow), and nearly all of them are held by code, not left to the storyteller.
Want dice on the table? A world can play by a rule system instead of Worldtable's own engine: stats on a sheet, dice you can see, and outcomes that come from the dice rather than the storyteller's mood. Start from one of six systems (Classic d20 from the SRD 5.1, Forged in the Dark, Moves, two d100 systems powered by BRP, and Hope and Fear), change any part of one, or describe your own in four answers. Rule systems are in beta.

Check your canon before anyone plays
Ask the storyteller anything ("Who really controls the water trade?") and it answers from your canon, and tells you how much of the answer your canon actually settles. The world review reads everything and turns contradictions, gaps and loose ends into a task list. Hob, the Studio's assistant, makes edits from plain words, and you can undo a whole reply.
Then the AI runs it
Invite your players with a link, or open the world to everyone. They type what their characters try; the AI reads it and grades it, the engine rolls and applies the result, and the AI writes what happened in your world's voice. Every named character keeps a file on each player, and the map, travel time, money and injuries are stored, not left to a prompt's memory.
Your model, your bill
Worlds run on Worldtable's AI with credits: building is free, every account starts with 50 free credits, and each player pays for their own turns. Or add your own key, from OpenRouter or any OpenAI-compatible provider, even a local model served with Ollama, LM Studio or KoboldCpp through a tunnel, and your players play free. On another provider, pictures and read-aloud are off.
What it isn't
- It isn't a person. The storyteller is a language model. The engine keeps it honest about facts and dice; what it writes is only as good as the model behind it.
- It isn't every genre. Worldtable is built for fantasy worlds: maps, kingdoms, magic, roads and ports.
- It isn't a wiki. A world here is built to be played, not published as articles. For a wiki, see World Anvil alternatives.
Questions
- Can an AI run my homebrew setting?
- Yes. Build or import it in the World Studio and an AI game master runs it for your players. The parts that matter most aren't left to the AI: the map, the peoples' limits, the rules and the money are held by the engine, and your prose (tone, histories, taboos) is handed to the storyteller every scene.
- Can I import my lore or my rulebook?
- Yes. Lore books from SillyTavern, Chub, NovelAI, Agnai and KoboldAI come in with no AI. Books (PDF, Word, Markdown, text) are read into your world, and a rulebook's abilities, creatures, gear, conditions and classes become working rules. Lore books and world files cost nothing to import; reading a book costs credits by its length.
- Can I use D&D rules?
- A world can use the Classic d20 rule system: the fifth-edition core from the SRD 5.1, with six abilities, eighteen skills, death saves, and an action and a bonus action a turn, plus a library of 316 spells and 334 monsters. Rule systems are in beta.
- Does the AI remember what happened?
- Every named character keeps a file on each player, and a character's whole history travels with them: first meetings, old deals, names and whole scenes. No AI remembers everything; what's kept is decided as you play, so it's a record of what happened rather than a transcript.
- Can I use my own AI model?
- Yes. Add an OpenRouter key or any OpenAI-compatible provider on the AI tab, including your own local model reached through a tunnel such as Cloudflare Tunnel or ngrok. Your players then play free.
- How much does it cost?
- Building is free and needs no API key, and every account starts with 50 free credits. A turn costs one credit and each player pays for their own: packs start at $5 for 200, or $12 a month for 650. On your own AI key, players play free.
