star history
PasteGuard intercepts text sent to AI services and uses Microsoft Presidio (ML-based PII detection) to replace sensitive information with placeholders before the prompt reaches the LLM. It supports 30+ PII types across 24 languages and can be deployed as a local proxy, browser extension, or app integration. The original data never leaves the user’s machine while the AI receives a context-preserving version of the prompt.
