Purify

Intercepts ChatGPT prompts and redacts sensitive information

Purify — Auto-Redact Personal Info in ChatGPT 🛡️ Automatically protect your sensitive information before sending prompts to ChatGPT TL;DR When you're typing fast, it's easy to accidentally include emails, phone numbers, SSNs, bank details, or location info in your prompt. Purify automatically redacts them before they leave your browser — and it costs nothing. What Purify Does Purify scans your ChatGPT prompt for personally identifiable information (PII) — emails, phone numbers, SSNs, credit card numbers, IPv4 addresses, GPS coordinates — and replaces them with safe placeholder tags. You stay in full control of what gets sent. There are two modes: - Purify: Redact only, so you can review and adjust before sending - Purify + Send: Redact and submit in one click, ideal when you're in a rush The UI shows floating buttons next to the composer in ChatGPT. The redaction mapping is held locally on your device, so nothing sensitive ever leaves your browser. Why You Should Install It You type real details into ChatGPT — email, SSN, banking, addresses — sometimes without thinking. Purify is a safety net. It helps prevent oversharing without changing your workflow. It's ideal for professionals, founders, job applicants, or really anyone sending real-world drafts to ChatGPT. Privacy-First Design 🔒 Everything is processed on your computer. No analytics, no data collection, and no servers seeing your content. Purify only requests minimal permissions required to inject the UI into ChatGPT and store your redaction map locally. It also adds the Sec-GPC: 1 header to reflect your privacy preference where supported.
