AIgis - Secure & Optimize AI Interactions

AIgis (pronounced like Aegis, the mythological shield) is a "Client-Side Privacy Firewall" that automatically masks Personally Identifiable Information (PII) and optimizes tokens before your prompts ever leave your device.

In an era of “shadow AI,” where sensitive data can easily end up in third-party language models if care isn’t taken with the data you enter, AIgis ensures that your privacy is protected while allowing you to fully leverage the capabilities of AI.

🛡️ ZERO-TRUST LOCAL MASKING: AIgis operates 100% locally in your browser. It scans your prompts and automatically replaces sensitive data—such as Emails, Phone Numbers, IBANs, IP Addresses, and File Paths—with unique, traceable placeholders (e.g., [EMAIL_1]). You choose exactly what gets masked and what passes through.

⚡ SEAMLESS RESTORATION: When the AI generates a response using your placeholders, AIgis automatically injects your real data back into the text seamlessly. You get the perfect answer, but the AI provider never sees your actual data.

📦 TOON OPTIMIZATION: AIgis uses Token Optimized Object Notation (TOON) to natively compress heavy JSON and code objects in your clipboard before you paste them into LLMs, saving you tokens and preventing context limits.

⚙️ SMART DEVELOPER MODE: Switch between 'Strict' mode to mask everything, or 'Developer' mode to smartly ignore safe programming variables like localhost or standard paths like ./node_modules/ to avoid breaking system code inputs.
