XUnity Auto Translator
Advanced translator plugin that can be used to translate Unity games
XUnity.AutoTranslator is an advanced plugin framework designed to automatically translate text in Unity-based games in real time by intercepting and replacing in-game text during rendering. It works by injecting itself into the game process and leveraging external translation services such as Google Translate, DeepL, or custom APIs to dynamically convert text into a target language. The tool supports both automatic translation and manual translation workflows, allowing users to refine or override translations through editable files. It integrates with popular Unity modding frameworks such as BepInEx, MelonLoader, and others, making it widely compatible with a large number of Unity titles. The plugin also includes mechanisms for caching translations locally to improve performance and reduce repeated API calls. It supports advanced features such as font replacement, text formatting adjustments, and even texture-based translation for embedded text. -

Argos Translate
Open-source offline translation library written in Python
Argos Translate uses OpenNMT for translations and can be used as either a Python library, command-line, or GUI application. Argos Translate supports installing language model packages which are zip archives with a ".argosmodel" extension containing the data needed for translation. LibreTranslate is an API and web-app built on top of Argos Translate. Argos Translate also manages automatically pivoting through intermediate languages to translate between languages that don't have a direct translation between them installed. For example, if you have a es → en and en → fr translation installed you are able to translate from es → fr as if you had that translation installed. This allows for translating between a wide variety of languages at the cost of some loss of translation quality. -

Crow Translate
Lightweight translator that allows you to translate and speak text
Crow Translate is a simple and lightweight translator written in C++ / Qt that allows you to translate and speak text using Google, Yandex, Bing, LibreTranslate and Lingva translate API. You may also be interested in my library QOnlineTranslator used in this project. Wayland does not support global shortcuts registration, but you can use D-Bus to bind actions in the system settings. For desktop environments that support additional applications actions (KDE, for example) you will see them predefined in the system shortcut settings. You can also use them for X11 sessions, but you need to disable global shortcuts registration in the application settings to avoid conflicts. On Linux to make the application look native on a non-KDE desktop environment, you need to configure Qt applications styling. -

pyVideoTrans
Translate the video from one language to another and embed dubbing
pyVideoTrans is an ambitious open-source multimedia processing project that assembles speech recognition, subtitle generation, AI translation, voice synthesis, and video assembly into a unified pipeline for converting videos from one language to another with embedded dubbing and captions. At its core it runs speech-to-text models to transcribe audio tracks, translates the resulting text into a target language using local or cloud-based translation engines, synthesizes new speech to match the translated subtitles, and then merges that speech back into the video, creating a fully localized media file. The tool supports both command-line and GUI modes, making it accessible to developers and creatives needing batch or automated processing. -

Google Translate for Mac
GoogleTranslate
Google Translate Mac Client. All known issues have been fixed and the user experience has been optimized, but there may still be a few bugs. In the new version, no matter which translation engine you use, it will first call the detection language interface of domestic Google Translate. In this case, the traffic of your proxy node is abnormal, which causes the request to be intercepted by Google, and you need to enter the verification code (you can also use + + to open the debugging optiontool commandto Icheck whether the request result is correct), so if this problem occurs, please replace your Proxy node or directly use domestic Google engine without proxy. Enter in the terminal sudo spctl –master-disableand press Enter to confirm. The password is the system power-on password. -

UnsupervisedMT
Phrase-Based & Neural Unsupervised Machine Translation
Unsupervised Machine Translation is a research repository that implements both phrase-based SMT and neural MT approaches for translation without parallel corpora. The neural component supports multiple architectures—seq2seq, biLSTM with attention, and Transformer—and allows extensive parameter sharing across languages to improve data efficiency. Training relies on denoising auto-encoding and back-translation, with on-the-fly, multithreaded generation of synthetic parallel data to continually refresh supervision signals. The project also provides scripts to fetch and preprocess monolingual data, learn BPE codes, and train cross-lingual embeddings that bootstrap unsupervised alignment between languages. Beyond the core EMNLP 2018 setup, the codebase exposes additional, optional capabilities such as multi-language training, language model pretraining with shared parameters, and adversarial training. -

Presage
the intelligent predictive text entry platform
Presage (formerly Soothsayer) is an intelligent predictive text entry system. Presage generates predictions by modelling natural language as a combination of redundant information sources. Presage computes probabilities for words which are most likely to be entered next by merging predictions generated by the different predictive algorithms. Presage's modular and extensible architecture allows its language model to be extended and customized to utilize statistical, syntactic, and semantic predictive algorithms. Presage's predictive capabilities are implemented by predictive plugins. Predictive plugins use services provided by the platform to implement multiple prediction techniques. -

OpenAI Translator
Browser extension and cross-platform desktop app based on ChatGPT API
Browser extension and cross-platform desktop application for translation based on ChatGPT API. I have developed a Bob plugin that utilizes ChatGPT API to provide global word translation on macOS. However, since not all users have access to macOS to benefit from the plugin, I have created this project! What began as a Chrome extension has now evolved into a multi-platform desktop app that I am currently developing. The desktop application does not support the pop-up icon after word selection. You must press the shortcut key to trigger the translation after selecting a word. It offers three modes: translation, polishing and summarization. Our tool allows for mutual translation, polishing and summarization across 55 different languages. Streaming mode is supported! It allows users to customize their translation text. One-click copying, Text-to-Speech (TTS). Available on all platforms (Windows, macOS, and Linux) for both browsers and Desktop. -
