DocStripper automatically removes noise from text documents: page numbers, headers, footers, duplicate lines, and empty lines. Choose between Fast Clean (instant rule-based) or Smart Clean (AI-powered with on-device LLM). Works entirely in your browser - no uploads, no sign-ups, 100% private. Upload a document, configure cleaning options, and download clean results instantly. Perfect for students, researchers, and anyone working with scanned documents or PDFs. Also available as a free CLI tool.
