# User Message LaTeX Rendering

::: info
**Note**: This feature is supported in version 1.3.7 and later.
:::

Automatically render LaTeX formulas in user messages as math notation.

## Overview

When you use LaTeX syntax in Gemini™ chat (e.g., `$E=mc^2$` or `$$\int_0^1 x^2 dx$$`), Voyager automatically detects and renders them as beautiful math formulas.

### Key Features

- **Inline math**: Wrap with `$...$`, e.g., `$x^2 + y^2 = r^2$`
- **Display math**: Wrap with `$$...$$` for centered, block-level formulas
- **Auto-detection**: Processes existing and newly sent messages automatically
- **KaTeX engine**: High-quality math rendering powered by KaTeX

## How to Use

1. Type a message containing LaTeX syntax in the Gemini chat input
2. After sending, formulas are automatically rendered as math notation
3. Inline math `$...$` renders within the text flow
4. Display math `$$...$$` renders centered on its own line

## Syntax Examples

| Input                                     | Description     |
| ----------------------------------------- | --------------- |
| `$E=mc^2$`                                | Inline formula  |
| `$$\sum_{i=1}^{n} i = \frac{n(n+1)}{2}$$` | Display formula |
| `$\alpha, \beta, \gamma$`                 | Greek letters   |
| `$\sqrt{x^2 + y^2}$`                      | Square root     |

## Notes

::: tip

- Only applies to user-sent messages. Gemini's replies have their own formula rendering.
- If LaTeX syntax is invalid, the original text will be shown as fallback.
