Makes AI text feel more human by removing em—dashes

Overview

What it is

Undash is a simple Chrome plugin that automatically removes long em dashes (—) from AI-generated text when you paste it anywhere: websites, social media, emails, and more. No setup needed. Just install, enable, and paste clean text instantly.

Intent

I need it when

Clean up AI drafts quickly without manual editing

The extension works instantly across web platforms (LinkedIn, Gmail, Twitter, Notion, Google Docs) with zero setup. Users can toggle it on/off and apply it to selected text via right-click, eliminating the need for manual find-and-replace workflows.

Streamline content preparation for social media and professional platforms

The extension works everywhere users write online, enabling founders, marketers, and professionals to quickly polish AI-assisted posts and content before publishing without switching tools or applications.

Make AI-generated text appear more human and natural

undash automatically removes em-dashes (—) as users type, paste, or right-click, eliminating a telltale sign of AI-generated content. This helps writers, students, and marketers present AI-assisted work that reads more naturally without the distinctive em-dash pattern.

Maintain privacy while editing text online

undash processes all text entirely in the browser with no data collection, tracking, analytics, or logins required. Users can confidently use it on sensitive content knowing nothing leaves their device.

Drop

Not a fit when

  • User needs to edit em-dashes in non-web applications or offline documents
  • User requires manual control over which em-dashes to replace rather than automatic replacement
  • User works primarily in browsers other than Chrome
  • User needs to preserve em-dashes for stylistic or formatting purposes in their writing
  • User requires advanced text formatting features beyond dash replacement
