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. -

MisakaTranslator
Galgame's Multilingual Real-time Machine Translation Tool
MisakaProject is a collection of all projects developed based on MisakaTranslator or its auxiliary functions. If you are interested in adding your own projects of related types to MisakaProject, please contact the author. MisakaPatcher added support for plug-in Chinese patch, so this tool is more suitable for players who like manual translation, and also provides another way for Chinese personnel who have difficulty unpacking packets to release Chinese patch. MisakaHookFinder is suitable for some games where the translator can not be used to directly get the text hook method. Users can search for the hook special code by themselves or directly use it to get the source text. At the same time, it also supports the clipboard to output the original text. -

STranslate
A ready-to-go translation ocr tool developed with WPF/WPF
STranslate is a lightweight, open-source machine translation front end that lets users translate text between languages using a variety of supported back-end translation engines or APIs, offering a simple GUI for quick translation tasks without needing to write code or use complex web UIs. The application is designed to be small, cross-platform, and flexible, giving users the ability to type or paste text and receive instant translations while optionally selecting the desired language pairs or switching between multiple service providers. By abstracting backend complexity, STranslate makes it easy for both casual users and developers to get translations in local apps, offline modes (where supported), or even integrate translation workflows into larger projects via plugins or scripting hooks. It often includes features like clipboard monitoring, keyboard shortcuts, history tracking, and configurable translation preferences that enhance daily productivity. -

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. -

GazeRecorder
WebCam Eye Tracking for usability testing
WebCam Eye-Tracker. GazeRecorder automatically records using ordinary webcams, where people look and what they engage with on their computer screens. In comparison with conventional eye tracking - that uses specialized technology and invites respondents to labs – GazeRecoreder is able to track people’s eyes with their own computers at home. Multiple state-of-the-art tracking algorithms communicate to identify the face, key features, eyes, iris and movements in 3D, allowing for the most accurate tracking possible, even when people move, lighting changes or the face is partially obstructed. You can also check out: GazePointer, which lets you move mouse cursor using your eyes. https://sourceforge.net/projects/gazepointer/ GazeRecorder Online Insight Platform: https://app.gazerecorder.com GazeCloudAPI real-time eye tracking API: https://api.gazerecorder.com Read more: https://gazerecorder.com -
