What is ChatGPT Upload Guard
ChatGPT Upload Guard automatically scans documents uploaded to ChatGPT for dangerous prompt injection attacks, jailbreak attempts and other security threats before they reach the AI. Every file is analyzed privately in the browser using a local AI model, so no data ever leaves the device. Real-time protection scans files instantly before they reach ChatGPT, smart detection identifies prompt injection, jailbreak attempts and data extraction threats, and user control lets people choose to block dangerous files or proceed with warnings. As AI tools become more powerful, malicious actors create files designed to manipulate AI systems, bypass safety measures, extract sensitive information or manipulate AI responses in dangerous ways; this extension acts as a personal security checkpoint providing an essential layer of protection for AI interactions. The workflow is simple: navigate to ChatGPT, upload a document as usual, the extension scans it with the local model, and instant feedback shows whether it is safe to proceed or threats are detected, so suspicious content can be blocked or continued with full transparency.
