Redacto

Local sensitive data masking before sending to public AI chats.

Redacto helps you prepare text before sending it to public AI chats. The extension locally detects sensitive and personal data in the current input field, shows found entities for review, and replaces them with markers like [PERSON_1], [EMAIL_1], [ORG_1]. For known legal aliases of an organization, variant markers such as [ORG_1] and [ORG_1#2] are supported. What Redacto can do: • Mask text before sending to AI chats • Show detected entities before replacement so you can review the result • Restore original text from markers within the current tab • Process text and .txt / .docx / .xlsx/ .csv / files via the extension's side panel • Create a JSON dictionary mapping markers back to originals, optionally encrypted with a password (AES-GCM) • Restore files using the masked file and the JSON dictionary (with password decryption if needed) • Run all processing locally — your text is never sent to an external server Supported: names, organizations, addresses, emails, phones, passport and tax IDs, bank details, card numbers, and more. Version: 0.2.0: We expanded Redacto’s file-processing capabilities by adding first-time support for .csv, improving .docx and .xlsx handling, increasing masking accuracy for business details, addresses, organizations, and monetary values in tables, and fixing Excel restoration so important structural elements are preserved more reliably. During the same period, we also updated the extension’s side panel, strengthened automated quality checks, and aligned the documentation with the product’s new capabilities.
