AIgis - Secure & Optimize AI Interactions

Secure & optimize your AI interactions. Locally mask secrets and optimize tokens in prompts before sending them to LLMs.

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 MASKING: AIgis operates entirely within a secure dual-storage environment right 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. 📖 CUSTOM DICTIONARIES & TEAM SHARING: Have internal project names or trade secrets? Define your own custom "forbidden words" in the dashboard. AIgis will automatically intercept and mask them as [CUSTOM_1] before sending. You can even export your configuration as a JSON file to easily sync and share strict dictionaries across your entire team! ⚡SEAMLESS RESTORATION, SMART COPY & PEEK MODE: When the AI generates a response using your placeholders, AIgis automatically injects beautiful interactive badges into the text. Hover to reveal your real data, click a badge to copy securely, or simply highlight and copy paragraphs normally - our Smart Copy feature automatically swaps the placeholders back to your real data in your clipboard! Need to see everything at once? Hold the "^" key to activate "Peek Mode" and temporarily unmask the entire page. 📦 TOON OPTIMIZATION: AIgis uses Token Optimized Object Notation (TOON) to natively compress heavy JSON and code objects before you send them to LLMs, saving you tokens and preventing context limits. 🗄️ AUTO-PRUNING VAULT (DUAL STORAGE): Your raw data never leaves your device. The secure Local Vault tracks your mapping placeholders in strictly isolated, non-syncing storage and automatically prunes expired entries (default 30 days) to reduce local forensic risk. Meanwhile, your general preferences and Custom Dictionaries use Sync Storage to seamlessly share your settings across all your devices. ⚙️ 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. 🌐 NATIVE INTEGRATION: Deep context-aware integration seamlessly hooks into the input fields of major AI platforms. Take control of your data privacy. Your data stays yours. The LLM provider only sees what you want them to see. ⚠️ Disclaimer: AIgis is provided "AS IS", without warranty of any kind. While this extension uses pattern matching and dictionaries to mask sensitive data, no regular expression or heuristic is 100% foolproof. Edge cases, typos, or obfuscated formats may bypass the detection engine. You are ultimately responsible for the data you enter into LLM platforms. The developers of AIgis are not liable for any accidental data leaks, privacy breaches, or damages resulting from the use or failure of this software. Always double-check your prompts if they contain highly sensitive or classified information.
