PasteSecure – PII Redaction for ChatGPT & AI

Prevent sensitive data leaks to ChatGPT, Claude, Gemini, and email. Redact PII, API keys, passwords, and financial data locally.

Stop sensitive data before it reaches ChatGPT, Claude, Gemini, email, tickets, and other web apps. PasteSecure is a local-first privacy extension that detects PII, secrets, and financial data as you type or paste, then lets you redact it before it leaves your browser. Scanning runs on your device. Nothing is uploaded for detection. What it detects • Personally identifiable information (SSNs, government IDs, emails, phones, street addresses) • Credit cards and other financial data • Usernames and passwords • API keys, access tokens, JWTs, and connection strings • AWS, GitHub, Stripe, and other provider secrets • PEM and private keys • Cryptocurrency wallets and related secrets • Internal IP addresses and hostnames • Medical and other regulated records • Custom patterns you define How it works PasteSecure scans on paste and while you type. When something sensitive is found, you get one clear summary instead of a stack of alerts. Open Details to review findings, preview original vs redacted text, ignore a category, redact values, or restore the original. Smarter by destination Not every site should be treated the same. AI chats and public tools stay strict. Trusted shopping, banking, and tax flows can follow lighter rules. Right-click any page and choose Trust this site to turn PasteSecure off there. Files and Vault Scan multiple attachments within the browser (up to 20 MB). Download a redacted copy in the original format, plus a TXT option when you need it. PasteSecure Vault can replace sensitive values with local tokens you can restore later, so you keep context without exposing the original secret. Controls and insights Use per-site policies, category toggles, profession presets, allowlists, custom patterns, pause timers, and alert muting. Review activity history, detection counts, top categories, 14-day insights, and exportable reports. Undo the last redaction when you need a quick restore. Use AI without sharing everything by accident It is easy to paste credentials, customer data, source-code secrets, or internal infrastructure details into an AI prompt without noticing. PasteSecure adds a last look before that text leaves your clipboard. Detect it. Review it. Redact it. Then send it. PasteSecure helps reduce accidental exposure. It cannot guarantee every sensitive item will be found. You remain responsible for what you share.
