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.
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.
Three steps — all local, all in real time.
Write your prompt to ChatGPT or Claude exactly as you normally would.
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.
The AI replies referencing the placeholders; Vailra restores your original data in your window. The AI never saw it.
Built for engineers, lawyers, healthcare, and finance professionals who use AI under NDA or regulatory constraints.
Your prompt content and the token↔original map never leave your device. No servers, no accounts.
Semantic detection via Chrome's built-in Gemini Nano, with a high-precision regex engine as fallback.
Detects and masks credentials, personal data, source-code identifiers, and financial data automatically.
Strips hidden prompt-injection artifacts from AI responses before they render.
