Redact documents 98% faster with AI-powered PII detection
Automatically identify names, social security numbers, credit card numbers and other sensitive data across documents and images, with suggested redactions you can review and approve.
Redactions are applied to the file itself rather than overlaid, so hidden text cannot be recovered through copy-paste, text selection or metadata inspection.
Process scanned documents, photographed pages and image-based PDFs with the same automation available for native digital files, without a separate OCR step.
Every redaction and review action is logged automatically, giving compliance and legal teams a verifiable record without maintaining manual logs.
Detect, humanize and verify AI content in one place
Scans up to 5,000 words at a time and highlights the specific sentences most likely to be flagged as machine-written, so you can see your text the way a detector sees it.
Rewrites AI-flagged passages with different sentence rhythms, vocabulary and tone, keeping your meaning while making the prose read like human writing.
Detectors for AI images, voice recordings, video and deepfakes, plus specialty document tools for checking whether a PDF or screenshot has been manipulated.
Detect and humanize directly inside Gmail, Google Docs or any web page without switching tabs.
