What problem does it solve?

This Skill solves the challenge of embedding recoverable hidden identifiers into text while preserving the ability to detect the watermark after partial edits, deletions, or inserted content.

Core Features & Use Cases

  • Robust Text Watermarking: Encodes watermark strings by controlling sentence lengths with Fountain Code redundancy and synchronization markers.
  • Watermark Extraction: Recovers embedded marks from processed text using sync-frame detection and decoding algorithms.
  • Use Case: Add a hidden ownership marker to a long article, generated document, or experimental text artifact and later verify the embedded watermark after content changes.

Quick Start

Use the text watermark fountain skill to embed the watermark "name_1" into the provided long-form text and return the verified watermarked version.
