Item media 1 (screenshot) for Invisible AI Character Detector & Remover

Overview

Detect, visualize, and remove invisible Unicode characters commonly introduced by AI tools like ChatGPT, Claude, and Gemini.

Spot and remove invisible Unicode watermarks (ZWSP/ZWNJ/ZWJ, BOM, bidi controls), special spaces (NBSP, thin/hair/en/em), variation selectors, and common confusables (smart quotes, long dashes, ellipsis, minus) on any page. Visualize targets inline (reversible), normalize in place, or clean via right-click ‘Invisible AI: Clean page’. All processing is local; nothing is sent off-page. Features: - Visualize targets as ⟦U+XXXX⟧ and restore safely. - Clean in place: replace when safe (e.g., NBSP→space, smart quotes→ASCII) or remove invisibles. - Options for Unicode Cf, special spaces, variation selectors, confusables, and newlines. - Context menu action to clean without opening the popup. - Privacy-friendly: no telemetry, no network calls, runs entirely in the page context.
