## What it is
A Python library that embeds invisible blind watermarks into plain text without changing its appearance or readability, using a password-protected scheme. The hidden message can later be extracted with the same password, and it survives platforms like WeChat, DingTalk, and Zhihu.

## Use cases
- embed invisible watermark in text to trace leaks
- hide a secret message inside plain text
- detect source of leaked documents or chat messages
- steganography for text messages
- watermark text shared on WeChat or DingTalk
- extract hidden watermark from copied text

## When to choose
- you need to embed traceable ownership info in plain text invisibly
- you want a simple pip-installable Python library with password protection
- you need watermarks that survive copy-paste across chat and web platforms

## When to avoid
- you need image or video watermarking
- you need cryptographically strong steganography resistant to adversarial analysis
- you need watermarks that survive text reformatting or OCR

## Facets
- artifact type: library
- maturity: active
- function: cryptography, security, privacy, nlp
- domain: security, privacy, developer-tools
- platform: python, windows, cross-platform
- tags: blind-watermark, text-steganography, invisible-watermark, data-leak-tracing, steganography, natural-language-processing, linux, macos
