Could you build this?
Partial Stripping invisible Unicode and EXIF/C2PA metadata is trivial, but detecting and removing statistical LLM watermarks (Kirchenbauer, Gumbel) requires specialized statistical algorithms.
What it would actually take: The service needs a pipeline stripping document metadata (using ExifTool or standard PDF/image libraries) and zero-width characters, combined with an LLM token-level re-paraphrasing or perturbed sampling module calibrated to disrupt Kirchenbauer green-red list distributions without altering semantic meaning. Implementing robust statistical watermark removal requires NLP researchers familiar with LLM watermarking literature.
