AnteRedact has no write-up on Specifiction yet; its figures are above.

Redacta is a free, open-source web tool for redacting or pseudonymising sensitive information in PDF files from plain-language instructions. It can identify and permanently remove names, email addresses, phone numbers, Social Security numbers, addresses, account numbers, and other personally identifiable information. It also detects embedded photos, signatures, logos, and screenshots for image redaction. Pseudonymisation replaces real names, addresses, and identifiers with fictional alternatives while keeping documents readable. Redacta says output PDFs retain their formatting, layout, fonts, and page structure. PDF parsing and redaction run in the browser through WebAssembly and MuPDF, and the site says files are not uploaded to a server. You provide your own Google Gemini or OpenAI API key, with requests sent directly to that provider. The free trial routes extracted text through a backend proxy. No signup, installation, watermarks, or usage limits are listed.
