# Free Letters to Numbers Convert Alphabet to Digits

## Bi-Directional Translation

Encode secret messages or decode ciphers instantly. Use the central Cryptex Cylinder to choose your mapping algorithm (A=1, A=0, Reverse), and watch the dual-plate interface translate your text in real-time, in both directions.

## Unlimited Local Ciphers

### Alpha Plate (A-Z)

| Cipher Mode                  | Delimiter         |
|------------------------------|-------------------|
| A=1 (Standard)              | Dash ( - )        |
| A=0 (Zero-Indexed)          | Space ( )         |
| A=26 (Reverse / Z=1)       | Comma ( , )       |

| Letter | Number |
|--------|--------|

| W      | 23     |
| X      | 24     |
| Y      | 25     |
| Z      | 26     |

### Numeric Plate (0-9)

| Chars Translated | Words Processed | Regex | Parsing Engine |
|------------------|-----------------|-------|----------------|
| 0                | 0               | 100%  | Local Privacy  |

## Super Features

### Bi-Directional Sync

No need to click a switch to reverse the tool. The Alpha and Numeric plates talk to each other simultaneously. Type letters to get numbers, or type numbers to get letters.

### The Cryptex Core

A centralized, mechanical-looking cylinder that houses your cipher settings. It includes a moving ticker tape that visually confirms the active mapping (e.g., A=1, B=2).

### Multiple Cipher Modes

Support for standard A=1 encoding, zero-indexed A=0 encoding for programmers, and the famous reverse Z=1 (Atbash-style) cipher for escape rooms and puzzles.

### Custom Delimiters

Control exactly how your numeric output is formatted. Choose between dashes (8-5-12-12-15), spaces, or commas to match whatever decoding system you are using.

### Zero-Latency Engine

There is no "Translate" button. Our JavaScript Regex engine fires on every keystroke, parsing strings and arrays in milliseconds to provide an instant flow state.

### 100% Client-Side

Whether you are encrypting a love letter, a secret password, or geocaching coordinates, the math happens strictly in your browser's RAM. Nothing is sent to a server.

## How to Use

### 01
#### Set the Cryptex

Use the central mechanical cylinder to select your desired Cipher Mode (Standard A=1 is default) and choose how you want numbers to be separated (Delimiter).

### 02
#### Type & Translate

To convert text to numbers, type in the top Alpha Plate. To convert numbers back to text, type in the bottom Numeric Plate. The translation happens instantly.

### Copy the Output

Once your secret message is ready, click the copy icon located at the top right of the target plate to save the encoded/decoded string to your clipboard.

## Why Cryptex AI is Superior

### Workflow

#### No Mode Switching

Standard tools force you to click a button to switch between "Letters to Numbers" and "Numbers to Letters". Our dual-plate design lets you do both effortlessly.

### Design

#### The Mechanical Aesthetic

We avoided boring side-by-side text boxes. The glowing plates separated by a metallic, moving Cryptex cylinder makes decoding feel like hacking a safe in a spy movie.

### Logic

#### Smart Tokenization

If you type "Hello World!", the engine knows to translate the letters, keep the spaces as word separators (`/`), and ignore punctuation, preserving the structure of your message perfectly.
