Save my S — AI Prompt Redactor is a Chrome extension designed to enhance user privacy while interacting with AI chat interfaces. This tool operates locally, ensuring that sensitive information remains secure by intercepting data before it is sent to large language models (LLMs). It scans for various types of sensitive data, including email addresses, credit card numbers, and API keys, providing users with immediate feedback through a confirmation modal that offers options to send a redacted version, the original text, or cancel the action.

The extension supports major AI chat websites, including ChatGPT and Claude, with a customizable feature for adding personal regex patterns. Its privacy-centric design means no data is sent over the network, and all detection occurs on the user's device. Ideal for engineers, support teams, and anyone concerned about privacy, Save my S provides a robust safeguard against accidental data leaks in an increasingly digital world.
