## Description

LunaTranslator is a real-time translation tool designed for visual novels and games. It functions as a multi-engine translation hub and text extractor that captures dialogue via memory hooking or optical character recognition to convert it into a target language.

The project distinguishes itself through specialized linguistic tools, including a Japanese text analyzer for sentence segmentation and phonetic readings. It also operates as a digital dictionary aggregator, querying multiple online and offline databases simultaneously to provide comprehensive vocabulary definitions for language learners.

The system covers a broad range of capabilities, including text-to-speech synthesis for audio generation and a sequential text processing pipeline for refining translations using custom glossaries and transformation rules. It supports various translation methods including commercial APIs, free online services, and offline engines, with the ability to extend functionality via custom translation scripting.

Text capture is handled through OCR engines, memory hooking, or system clipboard monitoring.
