ContextSlicer - Multi-Select Text & Copy

Hold Alt to select multiple non-contiguous text passages. Features 7-color highlighting, auto-citations, and batch copy.

ContextSlicer enables non-contiguous text selection, multi-color highlighting, and batch copying across web pages. Hold your trigger key—or switch on direct Highlighter Mode—to mark scattered passages across any article. Collected excerpts are automatically organized into color groups, preserved across page reloads, and ready to copy in a single step without altering the page layout. KEY CAPABILITIES Categorized 7-Color Collection Group excerpts across seven distinct colors (Yellow, Orange, Coral Red, Green, Mint Cyan, Sky Blue, and Purple). Export all color groups together or copy only the passages marked with a specific color. Highlighter Mode & Customizable Trigger Keys Prefer selecting text hands-free? Turn on Highlighter Mode to mark passages directly with your mouse, and click any highlighted text to remove it. Prefer modifier keys? Switch between Alt (Option on macOS), Ctrl (Command on macOS), or Shift anytime in the popup menu. Flexible Separators & Auto-Citations Choose how copied passages join together using None, Space, Newline, or Custom characters. Enable "Add Source" to automatically append deduplicated page titles and clickable links to your clipboard output. Persistent Highlights & Quick Undo Marked highlights stay in place even when you refresh the page or return to a suspended background tab. A movable floating toolbar remembers its screen position, and pressing Ctrl+Z (Cmd+Z) instantly undoes your last selection. Cross-Tab Session Basket Turn on "Cross-Tab" mode to gather excerpts across multiple open browser tabs into one unified list with automatic multi-page source references. Clean Page Experience & 100% Local Privacy Highlights text smoothly without modifying web page layouts or interfering with input fields, forms, or code editors. Runs entirely on your device with zero network requests, analytics, or external servers.
