Maskback

Redact before you paste into an AI. Restore after.

Maskback is a single offline HTML file that swaps names, emails, phone numbers, addresses, card and account numbers, URLs and IPs for placeholders before you paste text into ChatGPT or Claude, then restores the real values in the reply. Nothing leaves your browser. Pattern-based, so review before sending. Free up to 2,000 characters per pass; the paid file has no limit, file mode, a saved dictionary and exportable maps ($19 personal, $79 team).
