Every AI tool leaves invisible fingerprints in your text. SILK finds them — AI watermarks, hidden spaces, leaked credentials, personal data — and removes them before you share.
ChatGPT, Claude, and Gemini embed zero-width characters — invisible to the eye, detectable by software. They survive copy-paste and flag your content as AI-generated. SILK shows them inline and removes them.
Beyond invisible characters, AI tools create detectable patterns in word choice and token distribution. Our Pro tier uses Claude to paraphrase your text and neutralise these statistical fingerprints.
Emails, phone numbers, NI numbers, API keys, and JWTs travel silently in copied text. SILK finds them before they reach the wrong system and replaces them with safe tokens.
Everyone has controls on email. Nobody has controls on paste.
You write a proposal with ChatGPT, paste it into a document, and send it to a client. Unknown to you, zero-width characters mark every sentence. Their compliance team flags it as AI-generated. The deal stalls.
AI watermarksYou copy a section of a board pack to paste into an AI tool. Three lines below your selection sits the CFO's salary and a live acquisition target. It goes to ChatGPT. It leaves your device.
Personal dataA developer copies a config snippet to share in Slack. Four lines below sits a live AWS access key. It reaches 40 people. The key is valid for three more months.
CredentialsDrop in AI-generated text, an email, a CV, a contract — anything you're about to share.
Hidden characters appear as coloured badges inline inside your text at their exact position. You see the problem before you fix it.
