Admunio — AI Data Leak Protection and Prevention

Admunio — AI Data Leak Prevention Protect your business from accidental data leaks into ChatGPT, Google Gemini, and Claude. All analysis runs 100% locally on your device. No data is ever transmitted to any server — not even ours. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHY YOU NEED THIS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Your employees are using AI tools every day. And most of the time, no one is watching what they share. Studies show that 1 in 3 employees has pasted sensitive company information into a public AI tool. That includes passwords, API keys, client contracts, internal financial reports, customer data, and confidential business strategy. The problem is not bad intentions — it is habit. People paste information into AI tools the same way they Google something. They do not stop to think about where that data is going. Admunio stops the leak before it happens. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT ADMUNIO DOES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Admunio is a Chrome extension that runs silently in the background while your employees use ChatGPT, Google Gemini, and Claude. When someone types or pastes something into one of these AI tools, Admunio checks the content before it is sent. If sensitive content is detected, one of two things happens: → A warning appears, giving the employee a chance to review what they are about to share and decide whether to continue. → The message is blocked entirely, preventing highly sensitive content such as passwords and API keys from being sent at all. If the content is safe, nothing happens. The message sends normally and the employee's workflow is not interrupted. This all happens in under a second, entirely on the employee's device. No data is sent anywhere. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW THE DETECTION WORKS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Admunio uses two detection layers working together: LAYER 1 — INSTANT PATTERN DETECTION The first layer runs in under a millisecond using pattern rules. It catches well-known sensitive data formats instantly without needing an internet connection or AI model: • API keys (OpenAI, AWS, and other common formats) • Private keys (RSA, EC, SSH, and others) • Passwords and credentials in common formats • Payment card numbers • Email addresses LAYER 2 — LOCAL AI MODEL The second layer uses a real AI model that runs entirely inside your browser using WebAssembly. This model understands context, which means it catches sensitive content that patterns alone cannot identify: • Confidential business strategy and internal plans • Customer names, contacts, and account details • Financial reports and pricing information • Legal and contractual content • Personal data and private employee information • Proprietary technical information The AI model is nli-deberta-v3-small, an open-source model published by Xenova on Hugging Face under the MIT licence. It is downloaded once on first install (approximately 23MB) and cached locally. After the initial download, the model runs fully offline — no internet connection is required for it to work. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ THREE POSSIBLE OUTCOMES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✅ ALLOWED — The prompt is safe. Nothing happens. The message sends normally. No interruption. ⚠️ WARNING — The prompt may contain sensitive content. A clear modal appears inside the page, explaining what was found and why. The employee can choose to send anyway or cancel. This outcome is for content that is potentially sensitive but where the employee may have a legitimate reason to continue. 🚫 BLOCKED — The prompt contains clearly sensitive content such as an API key or password. The message cannot be sent. The employee must remove the sensitive content before continuing. Every outcome is shown clearly inside the page. No separate app, no dashboard to check, no notifications. The employee sees the result immediately where they are working. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY — THE MOST IMPORTANT PART ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Most security tools work by sending your data to their servers for analysis. Admunio works differently. Everything happens locally, on the employee's device, inside the browser. ✓ Your prompt text is never sent to Admunio's servers ✓ Your prompt text is never sent to Hugging Face or any other third party ✓ No analytics or usage data is collected ✓ No employee activity is logged or tracked ✓ No personal data leaves the device ✓ The AI model runs offline after the initial download This architecture has two benefits. First, it is genuinely more private — there is no server to breach, no database of prompts to leak. Second, it is faster — local analysis takes less time than a round trip to a server. Admunio's servers never receive your employees' prompt content. There is nothing for us to store, analyse, or accidentally expose. Full details are available in our privacy policy at www.admunio.com/privacy. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SUPPORTED AI TOOLS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Admunio currently protects on the three most widely used AI tools in the workplace: • ChatGPT (chatgpt.com) — all conversations including custom GPTs • Google Gemini (gemini.google.com) — the main Gemini chat interface • Claude by Anthropic (claude.ai) — all Claude conversations Admunio only runs on these three domains. It does not run on any other website you visit. This is intentional — we limit the extension's reach to exactly where it is needed. Support for additional AI tools is planned for future versions. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHO ADMUNIO IS FOR ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Admunio is designed for businesses and professionals who handle sensitive data and want to use AI tools without the risk of accidental leaks. It is particularly useful for: LAW FIRMS AND LEGAL PROFESSIONALS Lawyers and paralegals often use AI to draf…
