Everything You Need to Play

We've built a comprehensive virtual tabletop powered by cutting-edge AI, designed for both veterans and newcomers.

LLM Game Master

An intelligent AI that doesn't just read text—it runs the game. It understands mechanics, tracks narrative threads, and reacts dynamically to your party's most unpredictable choices.

Solo or Multiplayer

Dive into a deeply personal solo campaign when the mood strikes, or create a lobby and invite your friends for a classic cooperative party experience. The AI adapts to party size.

Built on Open Rules

Familiar gameplay right out of the box. masterless is built using robust open-license rulesets (including SRD 5.1 and 5.2), ensuring fair, balanced, and recognizable mechanics.

Play By Your Books

Access our curated library of rulebooks and settings, upload your own PDFs with custom lore and homebrew, or just describe an idea — the AI generates a full adventure crafted to the canons of the best modules.

Maps & Environments

Never get lost in the theater of the mind. The system generates and displays detailed maps for exploration and grid-based tactical combat to keep everyone on the same page.

Immersive Audio

Atmosphere matters. As your story shifts from a bustling tavern to a tense dungeon crawl, the AI seamlessly curates and plays background music to match the current mood.

Up Close

See the Engine in Action

Real screens from a live session — not mockups. Dice, the tactical map, and a fully generated hero.

An action card: the AI resolves an Investigation check with dice and modifiers.
Action Resolution

Rolls & resolves every action.

The GM applies your modifiers, rolls the dice and narrates the result — attacks, checks and saves, all by the rules, with the math done for you.

Tactical Map

See the battlefield, not just imagine it.

A generated, grid-based battle map tracks positions, tokens and ranges for every combatant — so the whole party is always on the same page.

The AI Game Master narrates the aftermath of a roll in prose.
Living Narrative

Every roll becomes a story.

The GM doesn't just print results — it turns each outcome into prose, reacting to your characters, the scene and what just happened on the dice.

Lobby settings: difficulty levels and master style.
Your Table

Set the tone before you play.

Pick a difficulty and a master style — from cinematic Rule of Cool to a grim, deadly campaign — and the AI runs the game your way.

Character Engine

Forge Your Hero.
Down to the Details.

Creating a character isn't just about picking a name. masterless provides a deep, intuitive character sheet that handles the heavy lifting, both mechanically and visually.

  • Mechanical Depth

    Automated tracking for stats, saving throws, spell slots, inventory, and proficiencies. Focus on the game, not the math.

  • Visual Generation

    Describe your Warlock's void-touched eyes or your Bard's silvan heritage, and watch our engine generate a stunning, unique avatar.

  • Instant Context

    The AI GM has access to your full sheet. It knows your passive perception, your fears, and your backstory, weaving them seamlessly into the narrative.

Overview: HP, armor class, attacks and resources.
Abilities & skills: ability scores, saving throws, skills, proficiencies and languages.
