文案净化 · CopyClean

Clean up AI-copied text: strip Markdown, fix layout, render formulas. Copy plain/rich text or export Word/PDF. Offline & private.

文案净化 · CopyClean is a browser side-panel extension that cleans the Markdown noise out of AI-generated content into tidy formatting in one click, then lets you copy it as plain text, rich text, or export to Word / PDF. Core features Smart cleanup: automatically strips Markdown symbols (asterisks, hashes, backticks, etc.), tidies messy lists and indentation, and removes extra blank lines while keeping the line breaks you actually need. Common structures are preserved, including headings, bold, quotes, code blocks, and tables. Four output modes: copy as plain text (symbols removed, text only), copy as rich text (with formatting), export to Word (locally generated .docx), and export to PDF (one-click A4 save). Formula rendering: a built-in offline KaTeX renders math formulas correctly in both preview and PDF with no network connection. History & drafts: drafts auto-save (not lost when you close the panel or restart the browser; cleared only when you click clear). History keeps your latest 30 entries, viewable, reusable, and bulk-deletable. Handy tools: paste (requests clipboard-read permission once on first use, then pastes directly), undo / redo, and clear. How to use Copy AI-generated content (text with Markdown symbols or messy formatting). Open the 文案净化 · CopyClean side panel and paste (auto-cleaned). Choose plain text / rich text / Word / PDF, then copy or export in one click. Use cases E-commerce operations and designers: quickly organize AI-written product copy and selling-point lists. Content creators and self-media: turn AI drafts into publishable clean text or documents. Students and researchers: handle notes and paper materials that contain formulas. Anyone who wants to tidy up AI output before using it. Privacy Runs entirely on the front end, with no server, no upload, and no third-party tracking. Your content stays only in your browser, locally. Data is stored in your browser's local storage and stays entirely on your device. Does not forcibly request clipboard-read permission; it only asks when you actively click paste, and refusing does not affect any other feature. KaTeX rendering and Word packaging are both done locally, with no CDN or cloud service dependency.
