# Text Obfuscator

Render English text into multiple obfuscation variants at once: number substitution (SSIS→55i5), hacker leet, small caps (RINHEE→ʀɪɴʜᴇᴇ), superscript, subscript, fullwidth, negative bubble, and mixed random. For bypassing crude keyword filters, unique handles, or playful decoration.

## Overview

Turn plain text into hard-to-detect or novelty variants, rendered all at once so you can pick the one that fits.

**Why "obfuscation" and not just "fancy text".** This tool is built for the use case the fancy-text generators skip: making text *less* recognizable — to slip past crude keyword filters, to generate a unique username/handle, or just for playful decoration. The leet/number maps here are deliberately denser and more aggressive than the standalone leet converter.

**The variants.**
- **Numbers** — letters become look-alike digits: `SSIS → 55i5`, `HELLO → H3LL0`. The classic "bypass" style.
- **Hacker Leet** — ASCII symbols + digits for every letter (`H → #`, `A → 4`, `K → |<`). Maximally obscured.
- **Small Caps** — lowercase rendered as miniature capitals: `RINHEE → ʀɪɴʜᴇᴇ`. Looks official, stays short.
- **Superscript / Subscript** — tiny raised/lowered Unicode letters. Great for footnotes-style handles.
- **Fullwidth** — every character stretched to full-width (ＡＢＣ), the "CJK aesthetic" look.
- **Negative Bubble** — black circle, white glyph (🅐🅑🅒). Eye-catching, used in bios.
- **Mixed Random** — each letter randomly assigned a different style. Chaotic and unique every time; set a seed to make it reproducible.

**Tips.**
- Pick *All variants* to see every style at once, then copy the line you want.
- Output is plain text — paste it anywhere Unicode is supported (most chats, bios, code comments). Some sites strip exotic Unicode; if one doesn't render, try Numbers or Hacker which stay in ASCII.
- Number/Hacker styles survive even in ASCII-only environments; the Unicode styles may not.

**Note on detection.** This defeats simple substring/regex keyword matching. It does *not* defeat semantic analysis or ML-based moderation — use responsibly.

## Inputs

- **Text** (textarea): e.g. RINHEE or SSIS — text to obfuscate
- **Mode** (select)
- **Random seed (optional)** (text): e.g. my-seed — makes Mixed mode reproducible
- **Preserve letter case** (checkbox)

## When to use

- When you need to bypass simple regex or substring-based keyword filters in chats or comments.
- When creating unique, eye-catching social media handles, bios, or profile names using stylized Unicode characters.
- When generating decorative text variants for code comments, gaming tags, or playful online communication.

## How it works

- Enter the English text you want to obfuscate into the input area.
- Select your preferred obfuscation mode, such as a specific style or 'All variants' to compare them side-by-side.
- Optionally configure settings like preserving letter case or setting a random seed for reproducible mixed-style outputs.
- Copy the generated obfuscated text directly from the output preview to paste it into your destination platform.

## Use cases

- Generating stylized, hard-to-copy usernames for gaming platforms and social media bios.
- Evading basic automated keyword blocks on forums that rely on simple text matching.
- Formatting text with small caps or superscript for decorative footnotes and unique digital signatures.

## Frequently asked questions

### Will this tool bypass all content moderation filters?

No. It only bypasses simple, exact-match keyword or regex filters. It does not bypass advanced semantic or machine-learning-based moderation.

### Do all websites support these obfuscated text styles?

Most modern platforms support Unicode styles like small caps and bubbles, but some legacy systems may strip them. Number and Hacker Leet styles use standard ASCII and are universally supported.

### What does the random seed option do?

The random seed ensures that the 'Mixed Random' mode generates the exact same combination of styles for the same input text every time.

### Can I preserve the original capitalization of my text?

Yes, you can check the 'Preserve letter case' option to maintain your original uppercase and lowercase formatting where the style allows.

### Is this tool free to use?

Yes, the Text Obfuscator runs entirely in your browser and is free to use with no usage limits.
