// Features

Built for security-conscious teams

Everything runs locally. Nothing leaves your machine.

⚡
Real-time, on-device detection
Named entities, regex patterns, and ML models run entirely in-browser. Zero latency, zero network calls, zero cloud dependency.
🎭
Replace, don't delete
Real values become labelled tokens like [PERSON] or [ACCOUNT_NUM]. Your AI still understands the context.
🌐
Works on every AI tool
ChatGPT, Claude, Gemini, Copilot, Perplexity. If there's a text box in a browser tab, PromptClean covers it.
// How it works

Three steps. Invisible until needed.

Runs silently until PII is detected — then prompts you to review.

01
Install the Chrome extension
One click from the Chrome Web Store. No account required. No permissions beyond the active tab.
02
Type normally into any AI tool
PromptClean monitors in the background. When PII is detected a subtle badge appears on the input field.
03
Review, redact, then submit
Click to replace all flagged entities — or cherry-pick which ones to keep. You're always in control.
