Chatglot

!Chat translation examples Chatglot is a Fabric client-side mod that translates Minecraft chat messages on the fly.
A translate button (✍ by default) is added to each chat message. Click it, or let auto-translate handle it, and the translated result is shown in chat either as a new line or by replacing the original message.

Client-side only. No server installation is required.

Features

• Translate button appended to every chat message (configurable label)
• Click-to-translate or automatic translation
• Result shown as a new line or replaces the original chat message
• Open the settings screen with F8 or /chatglot config
• Translate a specific message with /chatglot translate <id> !Config GUI

Translation Providers

Chatglot supports multiple translation backends. Switch between them in the settings screen.

Provider	Requires
default	Nothing. Uses an author-operated free GAS endpoint. Rate-limited, and auto-translate is unavailable.
gas	Your own Google Apps Script web app URL
deepl	DeepL API key
google	Google Cloud Translation API key
openai	OpenAI API key
gemini	Gemini API key
anthropic	Anthropic API key
azure	Azure Translator API key + region
codex	Browser OAuth (one-time, token stored locally)
translategemma_local	Windows only. Downloads llama.cpp + a TranslateGemma GGUF model, then runs a local backend over localhost

Recommended Providers

• GAS: Good if you want a free setup with your own Google account. Google Apps Script documents up to 5,000 Translate calls per day for consumer accounts, though quotas can change. See Apps Script quotas.
• Codex: Recommended if you already subscribe to ChatGPT. OpenAI states that Codex is included with ChatGPT Plus, Pro, Business, Edu, and Enterprise plans, with plan-based limits. See Using Codex with your ChatGPT plan.
• Azure: A good option if you want an official API with a free tier. Azure Translator F0 includes 2 million characters free per month according to Microsoft's pricing page. See Azure Translator pricing.
• TranslateGemma: A strong option if your PC has enough headroom for local inference. After setup, it runs locally over localhost, can be fast, and does not require a paid API for each request. It does require downloading the llama.cpp runtime and a TranslateGemma GGUF model.

TranslateGemma Local Backend

translategemma_local is a Windows-only local translation option. It does not run inference inside the Minecraft JVM. Instead, it uses a separate local backend process over 127.0.0.1 / localhost.

When you use the TranslateGemma setup buttons in the config screen, Chatglot:

• Downloads a prebuilt llama.cpp Windows runtime
• Downloads a TranslateGemma GGUF model file
• Starts llama-server.exe locally and sends translation requests to that local server

The default model is mradermacher/translategemma-4b-it-GGUF using translategemma-4b-it.Q4_K_M.gguf.

By default, Chatglot stores the local backend runtime, model, logs, and state inside:

• config/chatglot/local-backend/ when shared AppData settings are disabled
• %LOCALAPPDATA%/ChatglotLocal/ when shared AppData settings are enabled

You can also override the runtime path, model path, download URL, or shared directory from the config screen.

---

Shared Settings Storage

If useSharedAppDataSettings is enabled, Chatglot stores shared settings in %LOCALAPPDATA% so multiple launch profiles can reuse them.

This may include:

• API keys for supported translation providers
• Codex token file location and related model settings
• TranslateGemma local backend settings such as runtime path, model path, port, and shared directory

Shared settings are stored locally on your PC. They are not uploaded anywhere just because this option is enabled.

Privacy Notice — External Data Transmission

This mod sends chat text to external translation services. The destination depends on the provider you select.

• default provider: Chat text is sent to an author-operated Google Apps Script endpoint. However, requests pass through Google's infrastructure. See Google Apps Script Additional Terms and Google API Services User Data Policy.
• gas provider: Chat text is sent to the Google Apps Script web app URL that you configure. Requests are processed through Google's infrastructure. See Google Apps Script Additional Terms and Google API Services User Data Policy.
• openai provider: Chat text is sent to the OpenAI API using your API key. See OpenAI data controls.
• codex provider: Uses browser-based OAuth, stores the token locally, and then uses that token to send chat text to OpenAI services. The mod also fetches the available model list from https://modelapi.yoima.com/api/codex-models/list. No chat content is sent to that model-list endpoint.
• gemini provider: Chat text is sent to the Gemini API. For Google AI Studio / Gemini API usage, review the provider terms here: Gemini API Terms.
• deepl provider: Chat text is sent to the DeepL API. See DeepL Privacy Policy.
• anthropic provider: Chat text is sent to Anthropic services using your API key. See Anthropic Privacy Policy.
• azure provider: Chat text is sent to Azure Translator using your API key. See Data, privacy, and security for Azure Translator.
• google provider: Chat text is sent to Google Cloud Translation using your API key. See Google Cloud Privacy Notice.
• translategemma_local provider: Chat text is sent only to a local backend running on 127.0.0.1 / localhost. During setup, this mod downloads the llama.cpp runtime and the TranslateGemma GGUF model from a third-party hosting source configured by the mod.
