Select main page content, adjust any text selection, and copy clean chunks with source links and image controls. Select exactly what you need. Copy it your way. Percent Selector lets you resize text selections by percentage and prepare clean, manageable chunks for notes, documents, or AI tools. HOW TO USE • Press Cmd+A on Mac or Ctrl+A on Windows/Linux to select the page’s main content. • Or drag to select a passage, then press - or + to start adjusting it. • Press - to shrink your selection and = or + to expand it toward its original size. • Press P to toggle images, B to open copy tools, or Escape to clear the selection and close the overlay. FEATURES • Main-content detection helps exclude navigation, sidebars, and other page clutter. • Adjust selections in 10-percentage-point steps, or hold Shift for 5-point steps. • Include or ignore images when copying webpage selections. • See the selected percentage, character count, and estimated token count. • Preview clean text and split it into chunks using an estimated token limit. • Copy Markdown with the page title and source URL on every chunk. • Works with webpage text, supported text fields, and basic editable content. PRIVATE BY DESIGN All processing happens locally in your browser. No account, subscription, analytics, or AI service is required. Percent Selector does not upload your page content. PLEASE NOTE Token counts are estimates, not model-specific tokenizer results. Copy tools represent images as text links, not attached image files. Main-content detection may vary by website. Some browser pages, embedded frames, and complex editors are not supported. Reload existing webpages after installing to activate the extension.
