Roblox Assistant is the best place to start in Roblox Studio - it is built into Studio at no cost, can see your game place, and can write Luau scripts. Since April 2026, its planning mode can also break down, build and test larger tasks. If you want to understand why a script is failing or are working on a larger system, you can add Claude, which connects to Studio through its built-in MCP server.

This is one of the quick answers in the series Which AI for what? - 50 answers. I checked this on October 8, 2026.

Three options: free, best overall and for advanced users

Roblox Studio and Assistant are free. Claude Pro pricing varies by market. As of October 8, 2026, Claude’s terms require users to be at least 18. Younger users can use Assistant or ChatGPT with a parent’s permission.

My quick test

I gave Claude Sonnet 5.5, using the free Claude plan, a coin-collection script with four planted errors: a LocalScript in ServerScriptService, a folder named “Leaderstats” instead of “leaderstats”, a player reference taken from hit.Parent instead of using GetPlayerFromCharacter, and no protection against multiple touches. I tested it in Polish. Claude found all four errors and returned working code that made the coin disappear for five seconds, along with instructions on where to put the script. It also made one unnecessary criticism: it said the name “Monety” was wrong, though it was correct. The test cost $0.026.

What to watch out for

• Check where a script belongs, because AI tools rarely ask: a Script runs on the server (ServerScriptService), while a LocalScript runs for the player (for example, in StarterPlayerScripts).
• Don’t paste code from other people’s games or keys for external services into chat tools.
• Before publishing your game, test it in Play mode with two players (Test, Clients and Servers). Some server-related bugs only show up then.

Copy-and-paste prompt

The following is an English translation of the Polish prompt used in the original material. It is a translated example, not a new test.

I'm making a game in Roblox Studio. I'm writing in Luau.
What should work: [describe the mechanic, for example, the player collects coins and sees them on the leaderboard].
What happens now: [what isn't working, and the error message from the Output window].
Where the script is: [Script / LocalScript / ModuleScript] in [ServerScriptService / StarterPlayerScripts / Workspace].
Code:
[paste the code]
1. List the errors and explain each in one sentence.
2. Provide corrected code and say exactly where to put it.
3. Use game:GetService() and task.wait(), not deprecated functions.

Frequently asked questions

Which AI tool for Roblox Studio is free?

Roblox Assistant is built into Studio. ChatGPT and Claude also offer free options for explaining code, but you have to copy and paste the code manually.

Does Roblox Assistant work in languages other than English?

Roblox does not list the languages supported by Assistant in its documentation. English prompts are the safest choice. For explanations in another language, you could try ChatGPT or Claude.

Can you publish games with AI-generated scripts?

Yes. Roblox is developing Assistant to write code and build scenes. You are still responsible for your game, so test every script before publishing.
