About SafePrompt

SafePrompt is a local-first data loss prevention (DLP) and LLM firewall designed to prevent accidental exposure of sensitive information to AI services. The tool operates as a local agent that intercepts and scans prompts entirely on the user’s device before they reach platforms like ChatGPT, Claude, or Gemini. It detects and redacts secrets, personally identifiable information (PII), prompt injections, and other sensitive data without sending any prompt content to SafePrompt’s servers. The system supports file and image scanning, including OCR for scanned documents, and maintains a local audit log of blocked or redacted incidents. SafePrompt is intended for enterprise teams and small businesses that need to balance AI productivity with security compliance, offering features like custom detection rules, fleet management, and policy synchronization across devices. It is particularly useful for organizations handling confidential business documents, customer data, financial information, or proprietary source code.
