Description
Copy page text with PII redacted on-device before pasting into ChatGPT (or any AI). Names, emails, phones, secrets. Coprepaste copies the visible text of any web page to your clipboard with personally identifying information automatically redacted, so you can paste safely into AI chatbots like ChatGPT (or any LLM tool) without leaking names, email addresses, phone numbers, home addresses, dates of birth, URLs, account numbers, or API keys. One click in the toolbar. No account, no sign-in, no subscription. The extension is also open source, see https://github.com/AlecDusheck/coprepaste ── HOW IT WORKS ── Coprepaste runs an on-device machine-learning model (OpenAI's privacy-filter) entirely inside your browser. The page contents never leave your computer. The model is downloaded once on first use and cached offline thereafter. ── WHAT GETS REDACTED ── Names / people → [PERSON] Email addresses → [EMAIL] Phone numbers → [PHONE] Postal addresses → [ADDRESS] Dates (birthdays, etc.) → [DATE] URLs → [URL] Account / SSN-style numbers → [ACCOUNT_NUMBER] • Secrets, API keys, tokens → [SECRET] You can enable or disable any category from the extension's options page at any time. ── WHY NOT A REGEX TOOL? ── Names, postal addresses, and many secrets don't match a pattern. Regex-based redactors miss anything that isn't shaped like an email or a phone number. Coprepaste uses a token-classification neural network that actually reads context — so "Alice Smith" gets caught, but "Alice in Wonderland" does not. ── WHY NOT A CLOUD SERVICE ── Because sending your data to a remote server to get it redacted defeats the point. Coprepaste runs 100% on your device. No network traffic, no telemetry, no account, no logging, no analytics. ── USE CASES ── - Pasting customer support transcripts into ChatGPT - Sharing logs or error messages with Claude without leaking usernames - Summarizing a Gmail thread with Gemini without including email addresses - Getting Copilot to refactor a config file without exposing secrets - Sanitizing spreadsheets, CRM exports, or database dumps before feeding them to any LLM - Privacy-sensitive research: HIPAA-adjacent workflows, legal review, academic IRB compliance ── KEYBOARD-LIGHT WORKFLOW ── 1. Open the page you want to copy. 2. Click the Coprepaste icon in the toolbar. 3. Paste anywhere. The clipboard already has the redacted text; the original stays on the page. ── PRIVACY ── No data collection. No tracking. No account. The only network call this extension makes is a one-time download of the model weights from a static CDN on first use.
