AI script generator for Roblox Studio

Roblox AI Script Generator

Type what you want. RoCode writes the Luau and puts it straight into the place you have open in Studio. Not a chatbot you copy and paste from.

The short answer

Describe a Roblox script in plain English. RoCode writes the Luau, puts it in the right place in the Studio game you have open and can compile-check it. With plugin 3.9.11 or newer, it can also playtest your game in Studio and control a test character to check it works. Starter gives free credits every day with no card, and Pro is $9.99 a month for 150 credits.

Checked 22 October 2026.

Try

Free to start. Sign in, add the free RoCode plugin to Studio, then send your prompt in the RoCode chat.

Example prompt

Add a Script inside the Part named LavaFloor in Workspace. When any part of a player’s character touches it, set that player’s Humanoid Health to 0. Ignore anything that is not part of a player’s character, such as NPCs or loose parts. Use current APIs only.

Where it goes

Workspace
  LavaFloor [Part]
    KillOnTouch [Script] new

Script KillOnTouch, 16 lines of Luau

local Players = game:GetService("Players")

local lava = script.Parent :: BasePart

lava.Touched:Connect(function(hit: BasePart)
	-- Only react to parts of a player's character, not NPCs or loose parts
	local character = hit:FindFirstAncestorOfClass("Model")
	if not character or not Players:GetPlayerFromCharacter(character) then
		return
	end

	local humanoid = character:FindFirstChildOfClass("Humanoid")
	if humanoid and humanoid.Health > 0 then
		humanoid.Health = 0
	end
end)

ExampleA good result is short and does exactly what was asked. This one is written by us to show the pattern, from our guide to AI in Roblox Studio. What RoCode writes depends on your prompt, your place and the model.

What it actually does

It writes the script, then puts it where it belongs

Most AI script generators hand you a block of Luau and leave the rest to you. RoCode is a Roblox Studio plugin, so it does the rest.

Writes the Luau

You describe what you want at rocode.app and RoCode writes the Luau, creates the Script, LocalScript or ModuleScript, and parents it to the right instance.
Builds what the job needs

It sets the properties and builds whatever parts or interface the job needs. It works on the place you already have open, including the scripts you have already written.
Checks its scripts

It is told to compile-check every script it writes inside Studio, with warnings for wait, spawn and delay, requires and GetService names, and a failed check sends the run back to fix it, up to two times.

Playtests with plugin 3.9 or newer
Reads Studio’s Output window
Ctrl+Z undoes each batch

How it tests, reads errors and undoes

With plugin 3.9 or newer, in Build mode (the mode that makes changes), it can press Play for a test of up to 30 seconds and read the server and client errors and warnings. It reads Studio's Output window too, including the Server and Client lines from playtests you run, so it can work from real errors rather than guessing. Each batch of changes is marked as an undo point in Studio, so Ctrl+Z takes them back step by step.

Examples

From a sentence to working Luau

Scripts players notice, each with a guide that has the code. Each tile opens its guide.

IllustrationWhat the finished code in six of our guides does, not recordings of a RoCode run.

You type

"Add a shop where players can buy a speed boost with coins."

RoCode does
- Scaffolds a shop ScreenGui from its interface templates
- Writes the server script that handles the purchase and the currency check
- Writes the LocalScript that drives the buttons
- Compile-checks the scripts in Studio
You type

"Make a killbrick that resets the player instead of destroying them."

RoCode does
- Finds the part in your hierarchy, or creates one
- Writes the Touched handler with the reset behaviour
- Sets the properties on the part itself
You type

"My leaderboard isn't saving. Fix it."

RoCode does
- Searches your scripts and reads the leaderstats and DataStore code it finds
- Reads Studio Output from your playtest for the actual error
- Makes a targeted edit rather than rewriting the file

Real demand

What Roblox developers actually ask an AI to build

Most tools guess at this. We can measure it. Here is what people asked RoCode for first, across 34,336 opening prompts.

Share of 34,336 opening prompts, 4 December 2025 to 29 September 2026. A prompt can count in more than one row; about 60% match none.
What they asked for	Prompts	Share
Interfaces: GUIs, HUDs and menus	5,820	17.0%
Weapons and combat	2,787	8.1%
Movement: sprinting, dashing, flying	2,543	7.4%
Shops	2,218	6.5%
Fixing errors and broken scripts	1,829	5.3%
Simulators and tycoons	1,377	4.0%
Inventories	1,224	3.6%
Leaderboards	1,208	3.5%
Doors and teleporters	1,206	3.5%
NPCs	1,115	3.2%
Obbies	982	2.9%
Saving player data	957	2.8%

Interfaces come first

Interface work is the single biggest category by a wide margin, which is why RoCode ships ready-made layouts for shops, inventories, HUDs, dialogs, leaderboards and settings rather than making you build every frame by hand. A layout starts with placeholder items; the scripts that make it work are written separately.

Rather write it yourself?

If you would rather write these systems yourself, the linked rows open our Roblox scripting guides, with complete Luau for each one, and the Roblox Studio scripts page collects their main scripts by what they build, ready to copy.

How the rows are counted

An opening prompt is the first message of each RoCode chat that is still stored. Automatic keyword matching sorts them, whole words only and ignoring case, so “lobby” does not count as an obby and “datastore” does not count as a shop. An earlier version of this table matched parts of words, which pushed those two rows too high. No prompt is shown here. These are the rules:

A prompt counts in a row if it contains any of these words or phrases.
Row	Words and phrases
Interfaces	gui, guis, screengui, surfacegui, billboardgui, hud, menu, menus, ui, interface, textbutton, textlabel, imagebutton
Weapons and combat	gun, guns, weapon, weapons, sword, swords, combat, pvp, shoot, shooting, shooter, fighting, katana, blaster, rifle, pistol
Movement	sprint, sprinting, double jump, dash, dashing, fly, flying, walkspeed, jumppower, crouch, crouching, slide, sliding, wallrun, wall run, parkour, stamina, climb, climbing
Shops	shop, shops, store, stores, merchant
Fixing errors	error, errors, bug, bugs, buggy, broken, fix, debug, or the phrases “not working”, “doesn’t work”, “isn’t working”, “won’t work” and “does not work” (with or without the apostrophe)
Simulators and tycoons	simulator, tycoon, tycoons
Inventories	inventory, inventories, backpack, hotbar
Leaderboards	leaderboard, leaderboards, leaderstat, leaderstats, leader board
Doors and teleporters	door, doors, teleport, teleports, teleporter, teleporters, teleporting, teleportation
NPCs	npc, npcs
Obbies	obby, obbies, obstacle course, killbrick, killbricks, kill brick, kill bricks, kill part, kill parts, lava brick
Saving player data	datastore, datastores, data store, data stores, datastoreservice, profileservice, profilestore, or save, saves, saving, persist, persists or persistent followed within 30 characters by data, progress, stats, coins, cash, money, inventory or leaderstats

How it works

Three steps. The third one is the point.

1
Install the plugin
Get the RoCode plugin from the Creator Store and open a place in Studio. It connects by itself when Studio is signed in to the same Roblox account you use on RoCode; otherwise type the plugin's 8-character code into the chat.
2
Describe what you want
Plain English at rocode.app. You never have to write Luau yourself, and you never have to phrase it like a programmer.
3
It builds in your place
The plugin applies every change to the place you have open. Nothing to paste, nothing to wire up, and Ctrl+Z takes a batch of changes back if you do not like it.

The panel is an example of the steps in one run, not a recording. Playtest needs plugin 3.9 or newer, in Build mode.

Honestly

What it will not do

A finished game from one sentence

RoCode will not generate a finished, balanced, published Roblox game from one sentence. Nothing available today will, whatever the marketing says. What it does is build the systems inside a place you are already working on, which is the part that actually takes the time.
Code for games you do not own

It is for building your own game. RoCode's instructions tell it not to write exploits, executor scripts, backdoors or anything meant to harm other players or steal data, so it is not a source of scripts for games you do not own.
Anything without the plugin

It also needs the Studio plugin installed to do anything at all. The chat alone is just a chat. The plugin is what gives it hands, and that is the whole reason it can edit your hierarchy instead of describing what you should type.

Questions

Common questions

Is there a free Roblox AI script generator?

Yes. The Starter plan is free and gives you 1 credit a day, refilled at 00:00 UTC, with full access to the Studio plugin. On the free model that is enough for a small task or two a day. No card needed.

Can AI write Luau scripts for Roblox Studio?

Yes. RoCode writes Luau from a plain-English description, creates the script in the right place in your hierarchy, and can compile-check it in Studio without running it.

What is a Roblox AI coder?

An AI tool that writes Luau for your Roblox game from a plain-English request. Many only show code for you to copy. RoCode works inside Studio: it creates the scripts in your open place, can compile-check them and marks each batch of changes as an undo point.

Does RoCode work inside Roblox Studio, or do I copy and paste?

Inside Studio. You type in the web chat and the plugin applies the changes to the place you already have open. There is no copying and pasting.

What kinds of Roblox Studio scripts can it write?

Scripts, LocalScripts and ModuleScripts in Luau for the game you are building. RoCode creates each one in the right place in your hierarchy (see where each script type runs) and builds the parts or interface the job needs. In our count of 34,336 opening prompts, the most common first requests were interfaces, weapons and combat, movement and shops. It is for your own game: its instructions tell it not to write exploits.

Can AI make a whole Roblox game for me?

No. RoCode builds systems inside a place you are already working on: scripts, interfaces, structures and the logic that connects them. A finished game still needs you.

What if the script it writes has an error?

RoCode is told to compile-check every script it writes inside Studio, with warnings for wait, spawn and delay, requires and GetService names, and a failed check sends the run back to fix it, up to two times. With plugin 3.9 or newer, in Build mode (the mode that makes changes), it can also press Play for a test of up to 30 seconds and read the server and client errors and warnings. It reads Studio's Output window too, including lines from playtests you run, so it can work from the real error.

Can I undo what the AI changed?

Yes. Each batch of changes is marked as an undo point in Studio's own undo history, so Ctrl+Z takes them back step by step.

Can I use the Roblox AI script generator on my phone?

No. RoCode writes scripts into Roblox Studio, which runs on a Windows or Mac computer, and its chat needs a desktop browser: on a phone, the chat shows a desktop-only message. On a phone, the Build it in Studio button on this page shares or copies your prompt, so you can finish on your computer.
