Overview

Offsend Extension is a Chrome extension that helps users protect their sensitive information by detecting and masking API keys, tokens, private keys, emails, and other personal data before sending prompts to AI chat platforms such as ChatGPT, Claude, or Gemini.

When working with AI tools, it's easy to accidentally share sensitive information, which can compromise security and privacy. Offsend Extension solves this problem by scanning user input locally and automatically masking sensitive data, giving users control over what information is shared and what remains private.
