Privacy Protector for ChatGPT↗

This extension uses a customizable dictionary to replace sensitive data with dummy placeholders and offers both automatic and manual modes for anonymization.

Caviard↗

Caviard automatically redacts sensitive and personal information (PII) before sending prompts to AI services like ChatGPT and DeepSeek, with all processing happening 100% locally in the browser.
