Chat Translator
This mod introduces a chat translator that allows you to read the chat in your native language and translate your messages to a language of your chosing. This is achieved by a combination of on-device language identification and cloud-based translation services (both free & paid).
Installing & Using
You can install this mod on Fabric 1.21.5 (please note this mod requires Fabric-API to be installed!). After joining, you are able to use right-shift to open a settings GUI. Here, you can set your language, how we should translate incoming messages (automatic, manual, disabled) and how we should translate outgoing messages. For the current beta version you are unable to change the language identification & translation service used, but rest assured these are free and do not need to be configured in any way.
Achieving this in a free and easy way
To avoid something known as "vendor lock-in" and to keep this mod completely free you can decide what services and tools to use within this mod in the settings menu. Here is an overview!
Language identification
Language identification is used to determine what language a message is in.
| Service | Local | Free/Paid | Available in beta |
|---|---|---|---|
| Lingua | Yes (Local) | Free | Yes (Available) |
| FastText | Yes (Local) | Free | No (Not available) |
| OpenLID-v2 | No (Cloud) | Free | No (Not available) |
| OpenLID-v2-Pro | No (Cloud) | Paid | No (Not available) |
Translation
Translations are used to translate messages both incoming and outgoing.
| Service | Local | Free/Paid | Available in beta |
|---|---|---|---|
| LibreTranslate | No (Cloud) | Free | Yes (Available) |
| Tiny-Translator | Yes (Local) | Free | No (Not available) |
| DeepL | No (Cloud) | Paid | No (Not available) |
| ChatGPT | No (Cloud) | Paid | No (Not available) |
| MC-Translator | No (Cloud) | Paid | No (Not available) |
External services
So how does this mod use external services (all LI's & translators marked as cloud)?
For the following services we simply call their API and require an API-key from the user (stored locally):
- DeepL
- ChatGPT
For all other free services we deploy and maintain our own infrastructure. This can be maintained for free thanks to the relatively low computational requirements (OpenLID-v2, LibreTranslate) where we also limit the amount of messages a second that can be identified or translated.
For the remaining paid options that are maintained specifically for this use-case (OpenLID-v2-Pro, MC-Translator) we aim to specifically make AI models to perform better for the average minecraft chat, which costs a bit more of compute which we aim to deploy and allow anyone to use well below all other paid options (as the goal is not profit but accessibility).
