Picoo

Picoo is a Roblox AI game maker that runs as a plugin inside Roblox Studio. You describe what you want in plain English and it writes the Luau, generates 3D meshes from text prompts, and assembles complete game systems: combat, inventory, shops, pets, NPC dialogue, quests, tycoons and obbies.

It reads the place you have open on every prompt, so the code it writes fits the game you are already building instead of arriving as a generic snippet. It can patch scripts you wrote months ago, and it reads the Studio output window, so an error you just hit becomes the starting point of the next prompt.

Every generated script is parsed and checked against 16 Roblox API rules before it lands in your project, and each file goes into the correct service on its own: server logic into ServerScriptService, shared modules into ReplicatedStorage, player-side code into StarterPlayerScripts. A script that fails a check is rewritten and checked again before you see it.

31 vetted system templates back every generation, so asking for a tycoon twice gives you the same shape twice rather than a different tycoon each time.

Runs on Windows and macOS inside Roblox Studio. Premium only, no free tier: Pro is $19 a month or $12 a month billed yearly, Business is $49 a month or $35 a month billed yearly.
