"Every unvetted prompt is a potential data breach."
AiScrubber is a browser-based privacy gateway that detects and masks Personally Identifiable Information (PII) directly on your device — before your text is ever submitted to ChatGPT, Claude, Gemini, or any other public LLM.
No server. No account. No tracking. Your data never leaves your browser.
Built solo by Poorvith M P.
| Risk | What Happens |
|---|---|
| 🕵️ Corporate Espionage | Public AI models train on user inputs. Pasting proprietary code or strategy docs surrenders your IP permanently. |
| ⚖️ Regulatory Breach | Submitting unredacted patient data (HIPAA) or attorney-client communications through AI tools invites severe legal penalties. |
| 🔓 Data Leakage | Emails, phone numbers, SSNs, and IDs pasted into prompts are logged, stored, and potentially exposed. |
Paste raw text → AiScrubber detects PII → Replaces with safe placeholders → You copy clean output → Paste into any AI safely
Everything happens in your browser RAM. Nothing is sent anywhere.
- 🔒 Local-only processing — Zero server round-trips. Ever.
- 🧠 PII Detection Engine — Regex-based detection of emails, phone numbers, IDs, and more
- 🏷️ Smart Placeholder System — Replaces sensitive data with tokens like
EMAIL_1,PHONE_2 - 🗝️ Encrypted Vault Export — Password-protected keymap to reverse masking when needed
- 📄 Multi-format Export — Download sanitized output as TXT, DOC, PDF, or encrypted vault PDF
- ♻️ Session Recovery — Accidental tab close? Your last workspace is auto-recovered via
localStorage - 🌑 Dark-first UI — Clean, distraction-free workspace built for professionals
- 💸 Free forever — No account, no paywall, no ads
