To disable chat subtitles in Roblox Studio, the most likely fix is to turn off Automatic Chat Translation in the experience settings or disable chat- related UI in your game. In Studio, a common method is to set ChatTranslationEnabled to false in TextChatService, and some creators also disable the chat CoreGui with a LocalScript if they want the chat bar hidden entirely.

Studio setting

  1. Open Explorer.
  2. Select TextChatService.
  3. In Properties , set ChatTranslationEnabled to false.
  1. Also check Game Settings for Localization or Automatic Chat Translation and turn it off there if the option is available.

Hide the chat UI

If you mean the actual chat box or chat bar, put this in a LocalScript inside StarterGui :

lua

game:GetService("StarterGui"):SetCoreGuiEnabled(Enum.CoreGuiType.Chat, false)

That hides the default chat UI for the player.

Important note

If you only want to stop translated subtitles or system translation messages, disabling chat translation is the right move. If you want to remove the whole chat interface, you need the CoreGui chat setting instead.

Simple setup example

A quick setup many developers use is:

  • TextChatService.ChatTranslationEnabled = false to stop translation messages.
  • SetCoreGuiEnabled(Enum.CoreGuiType.Chat, false) to hide the chat panel entirely.

TL;DR

Turn off Automatic Chat Translation or set ChatTranslationEnabled to false if you want to disable subtitles/translation, and use SetCoreGuiEnabled(Enum.CoreGuiType.Chat, false) if you want to hide chat completely.
