AI Guard by Xu_2020_uX

AI Guard helps prevent accidentally pasting or sending sensitive information in AI chat web inputs.

It scans text in supported AI chat input fields and pasted content locally, highlighting potential matches such as API keys, passwords/tokens, internal URLs, and custom keywords or regex patterns. You can configure rules and choose between warning.

Features:
- Real-time scanning of AI chat inputs
- Highlights detected sensitive snippets
- Configurable warnings or send-blocking
- Paste detection
- Custom keywords and regex rules
- Built-in common sensitive patterns
- Chinese/English UI
- Local-only processing; no input content is collected or uploaded

Detection and blocking behavior may depend on page structure and site permissions.
