Redact your Word document before it reaches AI

Strip out names, emails, phone numbers, ID and card numbers from a .docx file — then hand the clean copy to ChatGPT, Claude, or anyone else. Everything happens in your browser. Your file is never uploaded.

Why "before AI" matters

The moment you paste a contract or résumé into an AI chat, that text leaves your control. CleanDoc is the step that goes before that: it removes the sensitive bits first, so the AI only ever sees a sanitised document.

It actually deletes — it doesn't just black things out

Highlighting text in black or changing the font colour only hides data; anyone can recover it. CleanDoc removes the underlying text from the file's XML, including the parts people forget: headers, footers, comments, tracked changes, footnotes and document properties.

Nothing is uploaded

The redaction engine runs entirely in your browser using local rules. You can disconnect from the internet and it still works. No account, no upload, no server.

What it catches automatically

• Email addresses
• Phone numbers
• National ID and bank card numbers (with checksum validation to cut false positives)
• IP / MAC addresses, licence plates
