Build Your Universe. Keep It Consistent.

Building the next Superman? You need Clark Kent, Kryptonite, Lex Luthor, the Daily Planet -- all connected in one universe. StudioBrain helps you build every piece and keep it all consistent while AI populates the gaps.

Free tier includes desktop app, BYO API keys, and 100 BrainBits/month.

Scroll to build your world

Step 1

Build a District

Every universe starts with a place. Pick a terrain type and AI generates the district -- name, climate, population, economy.

Step 2

Build a Location

Build a district first to see available locations.

Step 3

Build a Faction

Factions give your universe political depth. Define an allegiance and AI generates its ideology, ranks, and rivalries.

Step 4

Build a Character

Build a faction first to see available characters.

AI-Powered

Watch Your World Come Alive

AI adopts your character sheets, rules, and world lore to generate dialogue, backstories, and content that stays consistent with everything you've built.

Every Conversation Path, Written

Two AI providers follow every possible dialogue branch. Every "tell me more", every "how much?", every "how do I join?" -- all paths explored, all narrative lines generated.

Claude vs ChatGPT -- CH_elena_drake.md

Multi-Provider Generation

Generate from Claude, ChatGPT, Grok, Gemini, or local models. Compare results side by side.

Fusion

Select the best parts from each provider's response. Fusion combines them, verifies accuracy, and ensures nothing is hallucinated.

Universe Consistency

Every generation is checked against your rules, timeline, and existing entities. Characters talk to people who exist. Locations are real places in your world.

Art, Audio & 3D

Generate concept art, voice lines, and 3D models from your entity data. ComfyUI workflows inject your fields directly.

Fusion

The Real Magic

Claude, ChatGPT, Grok -- each has strengths and weaknesses. Fusion takes each response, you select the best parts, and it combines them into one verified result. No hallucinations. No broken lore.

Every entity mentioned is cross-referenced. Every date is timeline-checked. Every rule is enforced. This is how you keep a universe consistent at scale.

Visual Creation

From Data to Art

Turn your entity data into concept art, character portraits, environment renders, and animated previews. Generate from any provider or pipe it through ComfyUI.

World Rules

AI Screws Up. Rules Fix It.

Define world rules once. Every AI generation is validated against them -- no cell phones in your medieval fantasy, no 12-year-old generals, no referencing locations that don't exist. No more making every new hire read the entire history of your IP. Set up the templates and rules, and anyone on the team gets reproducible results.

Rules Engine -- Live Validation

Your Rules, Your World

NO_MODERN_TECH

No cell phones, GPS, modern vehicles, or electronics. Medieval-fantasy tech only.

FACTION_CONSISTENCY

Characters must use faction-appropriate language, weapons, and magic systems.

TIMELINE_INTEGRITY

Character ages, event dates, and historical references must be chronologically valid.

LOCATION_VALIDATION

Referenced locations, people, and entities must exist in the world database.

TONE_GUARD

Enforce narrative tone per district. Dark fantasy in Shattered Peaks, whimsical in Thornwood.

NAMING_CONVENTION

Names must follow faction naming patterns. Order uses classical, Shadow uses short aliases.

Rules are just markdown files

Every rule lives in _Rules/ as a markdown file with YAML frontmatter. Add, edit, or remove rules at any time. 17 built-in rule files cover characters, locations, dialogue, factions, tone, and more. AI reads them before every generation.

Templates

Any Entity Type. Instantly.

17 entity types out of the box. Need giant robots battling for the title of Iron Bot in your robot cooking deck builder? Create a template, add fields -- it shows up in the menu instantly. Templates plus rules equals reproducible results every time, from every team member, on every generation.
