Description
Inspect & sanitize invisible Unicode watermarks, C2PA metadata credentials, and statistical AI markers. Claude Watermark Remover & Checker is an ethical, privacy-first developer and research tool designed to inspect, analyze, and sanitize hidden digital watermarks from AI-generated text and images directly in your browser side panel. Operating 100% locally within your browser sandbox, this extension gives you complete transparency into invisible steganography, non-standard Unicode artifacts, and provenance metadata without sending your data to any remote servers. ================================================== 🔍 CORE CAPABILITIES ================================================== 1. 🧹 UNICODE STEGANOGRAPHY CLEANER & INSPECTOR • Detects and strips over 40+ invisible Unicode codepoints (Zero-Width Spaces, Soft Hyphens, Joiners, Directional Overrides, Tag Characters). • Normalizes exotic whitespace homoglyphs (Em-spaces, Hair spaces, Non-breaking spaces). • Resolves confusable Cyrillic / Greek homoglyph lookalikes back to standard Latin characters. • Smart Context Protection: Intelligently preserves legitimate emojis (ZWJ families, complex sequences) and complex scripts (Persian ZWNJ, Arabic letter marks). • Interactive Speech Bubble Popover: Hover over any in-text deletion in the visual diff viewer to inspect its exact Unicode hex, escape sequence (\u200b), and character description. • Raw Code Breakdown Table: Detailed table view displaying each removed artifact, codepoint address, and exact count. 2. 🖼️ IMAGE PROVENANCE & C2PA METADATA STRIPPER • Scans image binaries for C2PA Content Credentials manifests, JUMBF binary containers, and generator chunks. • Strips metadata from PNG (tEXt, zTXt, iTXt, c2pa), JPEG (EXIF, XMP, IPTC), WebP (EXIF, XMP), and SVG metadata tags. • Automatic binary CRC-32 recalculation ensures clean, uncorrupted image exports. 3. 🤖 STATISTICAL TOKEN DISRUPTION WITH AFFORDABLE AI • Disrupts green-list/red-list statistical sampling watermarks by paraphrasing through non-watermarking models. • Bring-Your-Own-Key (BYOK) support for DeepSeek V3, Groq (Llama 3.3 70B), OpenAI (GPT-4o-mini), OpenRouter, or 100% offline local Ollama. • Real-time lexical divergence scoring (Levenshtein + token perturbation tracker). 4. 🔒 100% LOCAL SANDBOX PRIVACY & DIAGNOSTIC AUDIT LOGS • Zero telemetry, zero analytics tracking, zero remote servers. • Full local session audit log with expandable JSON inspection and one-click JSON/CSV export. • One-click storage purge to wipe all preferences and keys instantly. ================================================== ⚖️ OPEN SOURCE ATTRIBUTION & DISCLAIMERS ================================================== • Open-Source Foundation: The Unicode sanitization engine is based on the open-source research project "claude-watermark-remover" by Guillaume Meyer (MIT License). AuthZ Pro developed this Chrome MV3 extension, image metadata stripper, and interactive interface. • Independent Tool: This extension is developed independently by AuthZ Pro and is not affiliated with, sponsored by, or endorsed by Anthropic PBC, OpenAI, or the C2PA Coalition. • No 100% Guarantee: AI watermarking technologies and statistical detection models evolve continuously. While this tool sanitizes known invisible Unicode artifacts and standard image metadata, no software can guarantee 100% bypass of proprietary detection systems.
