AI detection and writing verification built for schools and editors
Paste text or upload a document and get an overall AI probability score plus a sentence-by-sentence breakdown of which parts look machine-written.
Flags AI text from major model families including ChatGPT, Gemini, Claude, Llama, and others, rather than training for a single model.
A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.
Checks content for copied passages from outside sources so you can separate AI-generation questions from originality questions.
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.
