Users can choose their own translation provider, including OpenAI, Gemini, Google Translate, Azure Translator, and DeepL. API keys and preferences are configured in the options page.
Key features: - Inline page translation below original text - Selection translation and dictionary mode - Custom translation bubble styles - YouTube bilingual caption overlay - Image and PDF OCR translation - Prompt editor for LLM translation and dictionary prompts - Interface localization for English, Chinese, Japanese, Korean, French, German, and Spanish
