As answered by people managing Codility and RoCode.
RoCode's answer:
RoCode works inside Roblox Studio itself, not in a separate editor. You describe a game in a chat and it builds the map, the Luau scripts and the UI directly in the place you have open, then playtests it with a test character and fixes what fails before it reports the build as done. Everything it makes stays in your place, so you can read and change it.
RoCode's answer:
Most Roblox AI tools give you a script and leave the wiring to you. RoCode builds whole playable features in your place and tests them before it says it is done, so beginners end up with something they can press Play on. You can try it for free with 1 credit a day and no card, and paid plans start at $9.99 a month. It works on Windows and Mac, and you can sign in with your Roblox account.
RoCode's answer:
A Roblox Studio plugin written in Luau, a web app and server written in JavaScript, and large language models that plan the build and write the code.
RoCode's answer:
Roblox creators who want to build games faster, from beginners who have never written Luau to experienced developers who want the repetitive parts (maps, UI, saving data, leaderboards, shops) done for them. Over 50,000 creators have signed up.
RoCode's answer:
Roblox's own built-in AI wasn't good enough for building real games, and the number of Roblox AI tools appearing showed how big the demand was. So I set out to build one that actually works inside Studio: describe the game, and it builds and tests it in your place.
