## What Makes Translator Different

1. **Formula-safe translation**: LaTeX, MathJax, and KaTeX expressions are preserved using placeholder extraction — formulas never get corrupted by the translation model.
2. **Full privacy control**: Users configure their own API endpoint. Supports local LLMs (Ollama, LM Studio) for completely offline, LAN-only translation with zero data leaving the network.
3. **Academic-optimized layout**: Bilingual side-by-side rendering designed for dense academic reading. Section numbering, references, and citations stay intact.
4. **Universal API compatibility**: Works with OpenAI, Anthropic Claude, Google Gemini, DeepSeek, OpenRouter, and any OpenAI-compatible endpoint.

## Translation Modes

- **Hover translation**: Hold Shift over a paragraph to see inline bilingual text
- **Selection translation**: Select text and press Ctrl to translate the selection
- **Full-page translation**: Translate an entire page while preserving layout
- **YouTube captions**: Real-time subtitle translation on YouTube videos
- **Input translation**: Translate any pasted text via the float ball menu

## Supported AI Providers
