Chatcox

It helps users identify invisible Unicode marks that may carry hidden instructions, create misleading display order, or remain as formatting residue from documents and web pages. Text is scanned locally in the browser and is not uploaded, supporting private, evidence-focused review.

The tool offers detection and reporting, safe removal of hidden carriers, and optional cleanup for preparing text to publish. Users can compare marked and clean versions, review a list of changes, and export a forensic report in JSON without altering the original text. Its examples demonstrate zero-width characters, hidden prompt-injection payloads, bidirectional controls, variation selectors, and ordinary formatting artifacts.

chatcox distinguishes character-level markers from statistical AI watermarks, which it says cannot be verified or removed by this tool. It does not judge whether text was written by AI or provide detection scores. Instead, it explains findings and known ambiguities, while preserving legitimate characters used in emoji, multilingual writing, and typography.
