Parseltongue 4.0 — Text Encoder, Decoder & Steganography Tool

Selected Tool

Anti-Classifier Syntactic transformations via OpenRouter

Uses the same OpenRouter API key as PromptCraft. For research into how phrasing interacts with classifiers and filters.

Prompt to analyze

Latin-Root Analysis

This input contains affix patterns that skew toward destructive or lethal framing. Use the generated rewrites to neutralize tone before transformation.

💥 Tokenade Generator

Craft dense token payloads with emojis and zero-width characters

DISCLAIMER: Tokenade payloads can severely degrade model performance and crash UIs. Use for testing only. Do not deploy to production or target systems without explicit permission.

Danger zone: Estimated length {{ estimateTokenadeLength().toLocaleString() }} chars exceeds the safe threshold ({{ dangerThresholdTokens.toLocaleString() }}). Generating this will very likely freeze/crash your browser or downstream tools. Proceed only if you fully understand the risks.

Bijection custom encoded languages

Bijection learning builds a character mapping and wraps it in a prompt so the model is asked to use a custom script (alphapr). Haize Labs — Endless Jailbreaks with Bijection Learning

Latin-Root Analysis

This target content contains loaded Latin-root wording. Neutralizing it here propagates through the generated alphapr prompts.

Message Splitter

Split text into multiple copyable chunks. Each message can be transformed and encapsulated individually.

Mode Chunk Size Split Side (odd length) Words to Skip Min Word Length Split First Word Preserve Empty Lines Preserve Empty Lines Regex Pattern Include Delimiter Tokenizer Tokens Per Chunk

Transform

Apply transformations to each split message individually. Transformations are applied in sequence.

Encapsulation

Wrap each message with custom start and end strings. Use iterator marker to insert split numbers.

Iterator Marker This marker will be replaced with the split number (1, 2, 3...) Start String (optional) End String (optional)

Quick presets:

Split Messages {{ splitMessages.length }} message{{ splitMessages.length !== 1 ? 's' : '' }}

Message {{ index + 1 }}

Gibberish Generator

Custom Spelling Alphabets

Build ICAO-style spelling alphabets from any theme. Generate words with OpenRouter, or fill in all 26 letters manually. Saved alphabets appear on the Transforms page under custom_spelling.

No saved spelling alphabets yet. Create one manually or generate from a category with OpenRouter.

Category: {{ entry.category }}

Sample (hello world): {{ saSampleForEntry(entry) }}

Transform name Category / theme

No OpenRouter key — add one in Advanced Settings, or type each letter below manually.

Defaults to free OpenRouter models (no credits needed). Generation fills the grid below — edit any letter before saving.

{{ saFilledLetterCount() }} / 26 letters filled — ready to save
