Hushmark

Hushmark is a privacy gate for your AI workflow. Before you paste a document into an LLM or share it elsewhere, Hushmark finds and removes names, addresses, phone numbers, account numbers and other sensitive information from PDFs, Word documents, CSVs, text, HTML and images. Everything runs locally: no uploads, no accounts and no copies stored. Detection happens on your device, you review and adjust every match using templates and field groups, then export a secure copy with permanent redactions. The browser version is free to use, and the Mac app adds custom templates and batch redaction for a one-time purchase. Key Features: - Local Detection: sensitive fields are identified privately on your device, nothing is uploaded - Review and Customize: pick a template, adjust field groups and inspect every match before exporting - Permanent Redactions: export a secure copy that is safe to share with AI tools - Wide Format Support: PDF, DOCX, CSV, TXT, HTML, PNG, JPG and WEBP - Mac App Extras: custom reusable templates and batch redaction into a secure export folder Hushmark strips personal data from your documents locally before they reach an AI tool, free in the browser with a $4.99 Mac app for power users.
