Everything you need to
use AI safely

Aegis Personal runs entirely in your browser. Your prompts, your data — they never leave your device.

PII Auto-Masking

Automatically detects and pseudonymizes SSNs, credit cards, emails, phone numbers, and Korean RRN before they reach any AI.

9-Layer Threat Detection

Detects prompt injection, jailbreak, data extraction, social engineering, encoding attacks, and multi-turn manipulation in real time.

Silent by Default

No annoying popups. A subtle shield icon shows your protection status. Full alerts only when real threats are detected.

On-Device ML

A DistilBERT ONNX model runs directly in your browser for ML-powered classification — no cloud API calls needed.

CJK/Korean Evasion

Detects chosung separation, spacing manipulation, homoglyph attacks, and code-switching attempts unique to Korean/CJK text.

Weekly Reports

How it works

Three layers of protection, zero configuration needed.

1

You type normally

Use ChatGPT, Claude, or any supported AI service as usual. Aegis Personal watches silently in the background.

2

Aegis Personal scans in real-time

Every input is analyzed through 9 detection layers + ML classification. PII is detected and auto-masked before sending.

3

Threats blocked, PII masked

Dangerous prompts are blocked. Personal data is replaced with realistic pseudonyms. AI responses are auto-restored with your real data.

Works on 25+ AI services

Wherever you chat with AI, Aegis Personal is there.
