Your team's security layer for AI.
ARKN sits between your team and ChatGPT, Claude, and Gemini, automatically detecting and replacing sensitive information before it leaves the browser—without storing your prompts or interrupting how your team works.
Your employees already use AI.
The question is: what are they sending?
ChatGPT 4oCustomer Data Raw PII like full names, email addresses, and client contact details.
Claude AIMedical & Clinical Patient references, NHS identifiers, and sensitive health records.
Gemini AssistantFinancials & Credentials Bank sort codes, account numbers, and internal reference codes.
The problem isn't AI. It's what reaches AI. Your employees are already using ChatGPT, Claude, and Gemini to do real work. Every day, sensitive names, emails, financial information, customer records, internal identifiers, and confidential documents are copied into prompts.
ARKN intercepts every request locally, detects sensitive information, replaces it with secure tokens, and only then allows the prompt to continue. Your original data never leaves the browser.
Your data never becomes our data.
Sensitive information is protected locally before it reaches AI.
ARKN only allows the protected version of your prompt to leave the browser.
Protection happens locally
Every prompt is inspected inside your browser before it reaches ChatGPT, Claude, or Gemini.
Sensitive information is automatically detected and replaced in real time, so your team keeps working exactly as they do today.
ChatGPT 4oChatGPT 4oNothing sensitive is stored
ARKN never receives your original prompts, customer information, or business context.
Only anonymous protection metadata is synchronized so administrators can understand protection activity across the workspace.
Original prompts never leave your browser. Only protected placeholders are sent to AI.
Visibility without surveillance.
See protection metadata, never prompts. The dashboard shows counts, not content.
