Markless-GPT

A lightweight Chromium extension that cleans out hidden watermark markers (zero-width and similar) from any text you copy—whether via Ctrl +C/⌘ +C, programmatic “Copy” buttons, or cut events—so you always get plain, human-readable content.

🚀 Features

• Automatic Filtering
  Intercepts every copy- or cut-event on the page and runs it through a simple filterText() pipeline.
• Watermark Removal
  Strips zero-width spaces, non-breaking spaces, and other invisible markers often injected by AI models.
• Button-Click Fallback
  Detects “Copy” buttons, lets the page write first, then cleans up what lands on the clipboard.
• Inline Toast & Logging
  Brief “Text safely copied!” toast for feedback plus console logs of raw vs. cleaned text.
• No Extra Permissions
  Works without requesting any special "clipboardWrite" or host permissions—hooks into existing copy/cut handlers and the standard Clipboard API.

🛠️ Customizing the Filter

Open content-script.js and tweak the filterText function:

// Default removes common zero-width / invisible chars:
const filterText = input =>
  input
    .replace(/\u00A0/g, ' ')
    .replace(/\u202F/g, ' ')
    .replace(/[\u200B-\u200D\uFEFF]/g, '');

Feel free to extend it with your own regex rules, profanity filters, token redaction, or remote processing via a background script.

💡 Why Markless-GPT?

LLMs and other pipelines sometimes slip in invisible markers to tag AI-generated text. Markless-GPT makes sure anything you copy is free of these hidden artifacts—no permissions, no popups, just clean text.
