Roblox AI tools in 2026: what each one does
Roblox’s own AI features in Studio, in the Roblox app and inside games, where to find each one, and the third-party tools that make Roblox games and assets.
Short answer: as of September 2026, Roblox’s own AI tools are Assistant and Code Assist for building and scripting in Roblox Studio, generators for 3D meshes, procedural models, materials, textures and avatars, and APIs that put text, speech and 3D generation inside a game. Roblox is also testing Build, which makes a starting game from a description in the Roblox app. Outside Roblox, browser game makers, Studio plugins and graphics tools add more options.
This page covers what each tool does, where you use it, and the Roblox page that documents it. If you already know you want to turn an idea into a game, you can make a Roblox game with AI on the PromptBlox homepage.

AI for building and scripting in Roblox Studio
As of September 2026, Assistant is the AI helper built into Roblox Studio. Roblox’s guide says it can answer questions about Roblox development, create and change objects and scripts in the place you have open, insert Creator Store assets, explain code, and generate materials, 3D meshes and procedural models. It can also capture the 3D viewport to check how the scene looks. You open it with the Assistant button on the right of Studio’s mezzanine bar.
For bigger requests, Assistant’s Planning Mode writes a plan you can edit, and nothing runs until you click Build in the Assistant chat. The guide also notes that a script Assistant writes might not function flawlessly, so read it in the Script Editor and test it. In April 2026, Roblox announced a playtesting agent in beta that uses the player character to check how a game behaves.
Code Assist works in Studio’s Script Editor. It suggests lines or whole functions as you type, after a short pause or when you press Alt+\ on Windows (Option+\ on Mac), and Tab accepts a suggestion. Roblox lists its limits: a daily cap on suggestions, and suggestions that can use older APIs, or Lua instead of Luau.
The Studio MCP server is built into Studio for people who already use an AI coding tool on their computer. Once it is connected, that tool can read your place, write scripts, run Luau code and test the game in play mode in your open Studio session. You switch it on under Manage MCP Servers in Assistant’s menu.
For writing scripts in particular, read the Roblox script generator guide. For Studio plugins and how Studio fits with browser tools, see AI for Roblox Studio.
AI for 3D models, materials and avatars
- Mesh generation: in Assistant, the
/generate_meshcommand or a plain request such as “make a futuristic crate” returns a textured 3D mesh from text or from a reference image. Select a Part first to set the size, and cap the triangle count if you need a lighter model. The generation runs on Cube, the 3D foundation model Roblox introduced in March 2025. - Procedural models:
/generate_procedural_modelmakes a procedural model that rebuilds itself when you change its settings, such as a table that adds chairs as it gets longer. Assistant allows 50 in a rolling 24-hour window. - Material Generator: the Material Generator, in Studio’s Window › 3D menu, turns a short phrase into tiling material variants that you save as a custom material.
- Texture Generator: the Texture Generator is a beta tool, switched on in File › Beta Features, that textures a selected mesh from a text prompt. Roblox suggests the Material Generator instead for repeating surfaces such as floors.
- Avatar Auto-Setup: auto-setup turns a 3D model into an avatar body by adding an R15 rig, skinning, facial animation, cages for layered clothing and body-part partitioning. Roblox says it is in active development and results can vary.
AI you can put inside a Roblox game
Some Roblox AI runs while people play. As of September 2026, the AI on Roblox page lists these for developers:
- 3D generation in the game: GenerationService lets a game generate 3D objects from text prompts, including working models such as vehicles that drive. Roblox’s model generation guide explains how a preset schema splits a generated car into a body and four wheels.
- Text generation: TextGenerator gives a game a large language model, for uses such as NPC dialogue. Roblox requires the generated text to go through
TextService:FilterStringAsync(). - Speech: text to speech turns written lines into spoken audio, and speech to text turns what players say into text for commands, chat or captions.
A game that uses these features also takes on Roblox’s rules for AI in games, covered in the safety section below.
Build: Roblox’s text-to-game tool
Build is a tab in the Roblox app. You describe a game, and Roblox says Build generates a starting point to iterate on, playtest, share with friends or publish (Roblox newsroom, July 16, 2026). It opened as a public alpha in New Zealand on July 28, 2026.
At RDC on September 11, 2026, Roblox said the alpha is expanding to Serbia and Singapore and adding an asset library, desktop access and what it calls iterative control. Roblox says creators published about 9,000 games with Build after the New Zealand launch. The same post announced Scene Generator, prompt-to-scene creation for both Build and Studio, “coming later this year.”
During the alpha, Build is for age-checked users 9 and older, and Roblox says published Build games that pass its safety checks are available to age-checked users 16 and older. Roblox plans a base-level version at no cost, with paid options for power users. Roblox’s Creating with Build article has the current availability, and PromptBlox vs Roblox Build compares the two workflows.
Third-party AI tools for Roblox
Tools from other companies fill different gaps. They are not made by Roblox, and each has its own account, prices and terms.
Browser game makers
A browser game maker builds a first version of a whole game before you open Studio. PromptBlox is one, for creators 13 and older. You describe the game in chat or add a reference picture, PromptBlox makes one concept image as a visual reference, and then it builds the world and its Luau gameplay scripts while you follow a 3D preview. You refine the same saved project in chat, export it as a .rbxlx place file on any plan, Free included, and playtest and publish it in Roblox Studio on Windows or Mac.
To try it, make a Roblox game with AI from the PromptBlox homepage. The best AI Roblox game makers, compared puts the other options side by side.
Studio plugins
Plugins add AI inside Roblox Studio. Lemonade and Rebirth are two, with fact-checked comparisons on this site: PromptBlox vs Lemonade and PromptBlox vs Rebirth. BloxAI (bloxai.net) is a code editor for Roblox scripts that connects to Studio through its own plugin and shows each proposed change for you to accept or reject. Before you install any plugin, go through the checklist in AI for Roblox Studio.
Graphics tools
Some tools make the images a game shows on Roblox rather than the game itself. RBLX/ai (rblxai.com), for example, makes game icons, thumbnails and logos. Its terms say users should be at least 18.
How to choose a Roblox AI tool
Start from what you have and what you need:
- A place open in Studio: ask Assistant for changes, and let Code Assist help while you type.
- A 3D object, material or avatar: use mesh generation, procedural models, the Material or Texture Generator, or Avatar Auto-Setup.
- Only an idea: try Build where it is available to you, or a browser game maker such as PromptBlox. Either way, the first version is a starting point to playtest and refine.
- A game that should use AI while people play: use Roblox’s in-game APIs, and read its rules for AI in games first.
- An AI coding tool you already use: connect it to Studio through the Studio MCP server.
Safety, age and privacy rules
Roblox’s rules apply to AI-made content like anything else. As of September 2026:
- Moderation. Roblox’s page on games with generative AI says content made with AI must follow Roblox’s Community Standards. Inputs and outputs of Roblox’s own APIs, such as GenerationService and TextGenerator, go through Roblox moderation. With third-party AI, the creator is responsible for what players see.
- AI conversations in games. If players can interact with a generative AI model in your game, you disclose it in the Content Maturity questionnaire and show players a notice that they are talking to AI. Games built around ongoing AI conversations, or that remember past conversations across sessions, need a Restricted label, which keeps them away from users under 18.
- Build ages. During the alpha, Build is for age-checked users 9 and older, and published Build games reach age-checked users 16 and older (Roblox, July 2026).
- Going public. New games start private. Roblox’s publishing guide says making a game public needs an age check and the content maturity questionnaire.
- Your data. When you publish a game, Roblox asks whether to share its data for AI training; for games published on or after July 10, 2024, the default is on. You can change the default under Settings › Data Sharing on the Creator Hub (AI data sharing). Roblox also says your code is not used to train Code Assist and is not suggested to other users, except code posted to free marketplace items.
- Third-party age rules. PromptBlox is for creators 13 and older, and creators aged 13 to 18 should have a parent or guardian review its Terms. BloxAI’s terms require users to be 13 or older, with a parent’s or guardian’s consent under 18. RBLX/ai’s terms say 18 or older.
Read a tool’s terms before you sign up, and never type your Roblox password into another site. A tool that connects to your Roblox account should send you to Roblox’s own sign-in page.

Frequently asked questions
What AI does Roblox have?
As of September 2026, Roblox Studio includes Assistant, an AI helper for questions, scripts, objects and generated 3D content, and Code Assist, which suggests code as you type. Studio also has generators for meshes, procedural models, materials and textures, plus Avatar Auto-Setup. Games can use Roblox APIs for text generation, speech and 3D generation. Roblox is also testing Build, a text-to-game tool in the Roblox app, in a few countries.
What is the best AI for Roblox?
It depends on the job. For help inside a place you have open in Studio, Assistant is built in. For 3D assets, use Roblox’s mesh, material and texture tools. For a first version of a whole game from a description, try Roblox Build where it is available or a browser game maker such as PromptBlox, then playtest and refine it.
Is Roblox AI free?
Assistant and Code Assist are part of Roblox Studio, which is a free app for Windows and Mac. Roblox documents some limits, such as 50 procedural models in a rolling 24 hours and a daily cap on Code Assist suggestions. Roblox says a base-level version of Build will be available at no cost, with paid options for power users. Third-party tools set their own prices; PromptBlox has a Free plan with Light builds and a small weekly usage allowance.
Can AI make a whole Roblox game?
AI can make a first version. Roblox Build, where it is available, and browser game makers such as PromptBlox turn a description into a starting game. Expect to playtest it, fix what does not match your idea and refine it before you publish. Roblox has also announced Scene Generator for prompt-to-scene creation in Build and Studio.
Can I put AI inside my Roblox game?
Yes. Roblox offers APIs that generate text, such as NPC dialogue, turn text into speech and speech into text, and generate 3D models. Generated text must go through TextService filtering, AI interactions must be disclosed in the Content Maturity questionnaire, and games built around ongoing AI conversations need a Restricted label, which keeps them away from users under 18.
Are AI tools for Roblox safe for teens?
Each tool sets its own rules, so check them before you sign up. Roblox says every generation from its AI tools goes through the same moderation and Community Standards as the rest of the platform, and the Build alpha is for age-checked users 9 and older. PromptBlox is for creators 13 and older, and some third-party Roblox tools require users to be 18. If you are under 18, have a parent or guardian review a tool’s terms with you.
