PII Redactor for Gemini

Try it out! (Just double-press ⇧ Shift after typing your prompt to activate.)

Why this project came to be

I found myself constantly going back to manually redact sensitive inputs from my prompts, and quite frankly, I'm too lazy to keep doing that by hand.

What's cool about this, you ask?

• LLM Enabled: Intelligent PII detection and redaction using local LLMs.
• In-Browser: All processing happens locally within your browser—no data leaves your device.
• Near-Instant Redaction: Optimized for speed to minimize friction.
• Response Rehydration: Automatically restores redacted information in Gemini's responses for a seamless experience.

Stack

• Framework: React, TypeScript, WXT
• UI: Mantine
• AI: WebLLM (running Llama-3-8B-Instruct in browser)
