Brickbrain

One AI for the whole Roblox game.

It plans a game with you, builds it in Roblox Studio and checks its own work – and it remembers what worked.

Lava ObbyStage 5 of 9 · Scripts

Build me a lava obby: 5 platforms, checkpoints, lava and a finish.

Got it. Two questions first:

One player or several?
How long should one round take?

Solo, about three minutes.

01 Asks first

Asks before it builds.

Describe your game in one sentence. Brickbrain asks the questions that change the plan – how many players, how long a round takes – before it builds anything.

02 Plans

Plans the whole game.

Every answer goes into one plan, in the order games are really made: design, models, world, animations, scripts, UI, sound, effects and testing. You see every task, and what's already done.

03 Builds

Builds in Roblox Studio.

Brickbrain connects to Roblox Studio through Roblox's own Studio MCP server. Scripts and parts land straight in the open place – no copy and paste.

04 Tests

Tests its own work.

After each step it checks the code and runs a playtest in Studio – in the Lava Obby session: ten seconds played, zero errors. When a decision is yours, it stops and asks.

05 Learns

Learns from every project.

Plans, scripts, decisions and lessons live in its own second brain – plain Markdown files on your PC. Brickbrain reads the lessons in every new chat, so the next game starts smarter.

Lava kills on the server, never on the client.
One spawn point per checkpoint.
Playtest after every script.

How it works

Nine stages. One order.

Brickbrain builds every game in the same order, from the first idea to the release. Not every stage is automated yet – that's the roadmap.

Not public and not for sale

App

Desktop app for Windows

Interface in English and German

Roblox Studio

Connected through Roblox's official Studio MCP server

Writes scripts and parts into the open place

Runs playtests and reads the output

AI models

Local via Ollama – we run gpt-oss:20b, a 20-billion-parameter open model, on our own PC

Optional: Gemini, Claude or OpenAI models through their APIs

Compact mode for small models: only the tools the current stage needs

Brain

Plain Markdown files on your own PC

Handbook, pipeline, lessons – and one folder per game with its plan and chat

Data

With a local model, project knowledge stays on your machine

We train only on data we created, licensed or have permission to use

Our games first. Public once it's proven.

Brickbrain is in early development. The prototype asks questions, plans a game and puts scripts and parts into Roblox Studio. It isn't public and far from finished – this page shows where we're heading.
