Overview
Mask sensitive data before sending to LLMs. Auto-restore in responses. Local-only, zero telemetry.
SecurePaste keeps confidential text out of LLM training data and logs by intercepting the paste action on Claude, ChatGPT, and Gemini. HOW IT WORKS 1. Paste your text into the LLM's input. 2. SecurePaste scans for emails, phone numbers, IP addresses, credit cards (Luhn-validated), SSNs, names, organizations, and your own custom keywords. 3. A confirmation bar shows each finding. Click MASK ALL or pick selectively. 4. Selected items are replaced with opaque tokens like [[ANON_1]] before the request reaches the model. A short privacy note tells the model to preserve them verbatim. 5. When the response streams in, SecurePaste swaps the tokens back to the originals in the page DOM. You read the unredacted answer; the model only ever saw the masked version. PRIVACY-FIRST • Zero outbound network requests • Zero telemetry, analytics, or third-party SDKs • Token mappings live in chrome.storage.session — cleared when the tab closes • Custom keywords sync via chrome.storage.sync between your own logged-in Chrome instances SUPPORTED SITES • claude.ai • chatgpt.com • gemini.google.com PERFECT FOR • Engineers pasting stack traces with internal hostnames • Lawyers and consultants drafting client work • Anyone sending API keys, customer names, or financial data into a chatbot by accident • Privacy-conscious users who want a tangible safety net KEYBOARD-FRIENDLY Action bar focuses MASK ALL automatically. Press Esc to dismiss without masking. Tab to step through chips. WCAG 2.2 AA accessibility throughout the popup. LIGHT + DARK THEMES Auto-follows your OS preference, or pick a theme manually from the popup. Sync's between extension popup and in-page UI.
