100% on-device · zero egress

Your secrets never leave your device.

Vailra masks sensitive data in your ChatGPT & Claude prompts — on your device, before the request ever leaves your browser — then un-masks the reply in your window.

No account. No cookies. No telemetry. Works with ChatGPT & Claude.

The problem

People paste API keys, source code, and personal data into AI tools every day — and in 2025–26, extensions with hundreds of thousands of users were caught quietly harvesting those very chats. Trusting the tool isn't enough; the data shouldn't leave in the first place.

How it works

Three steps — all local, all in real time.

1

You paste

Write your prompt to ChatGPT or Claude exactly as you normally would.

2

Vailra masks it

On-device AI (Chrome's Gemini Nano, with a regex fallback) detects secrets and swaps them for synthetic placeholders before the request leaves your browser.

3

You get the real answer

The AI replies referencing the placeholders; Vailra restores your original data in your window. The AI never saw it.

Why Vailra

Built for engineers, lawyers, healthcare, and finance professionals who use AI under NDA or regulatory constraints.

🔒 Zero egress

Your prompt content and the token↔original map never leave your device. No servers, no accounts.

⚡ On-device AI

Semantic detection via Chrome's built-in Gemini Nano, with a high-precision regex engine as fallback.

🧩 API keys, PII, code & finance

Detects and masks credentials, personal data, source-code identifiers, and financial data automatically.

🛡️ Inbound defense

Strips hidden prompt-injection artifacts from AI responses before they render.

Verifiable trust. The personal edition makes no network calls of its own — no analytics, no cookies, no telemetry. Optional team analytics (enterprise) is opt-in and sends metadata only, never content.
