Decision brief

PROMPTPurify, licensed under MIT, provides an ai-safety solution with a focus on jailbreak-detection and prompt-injection-protection for LLM applications without relying on regex or signatures.

Good fit when

  • - When you require compact model solutions that outperform larger open-source guards.
  • - If your application demands prompt-injection detection, especially in contexts where AI security is paramount like in CTF events.

Avoid when

  • - Avoid using PROMPTPurify if your project requires regex or signature-based methods for security purposes, as this tool does not support them.
  • - Do not use it if you are looking for comprehensive AI-security solutions that extend beyond prompt injection and jailbreak detection.
Pricing:
freemium - The SDK and model weights of PROMPTPurify come under the MIT license, allowing free usage. However, the full extent of features or services might require a premium setup.
Requirements:
- This tool is built with TypeScript.; - Ensure familiarity with TypeScript for efficient integration.
