Prompt Injection Guard

Prompt Injection Guard overview

Prompt Injection Guard helps secure AI prompts by adding instruction-isolation and input-safety rules. It is built for teams and individuals who use prompts in support, automation, retrieval, and analysis workflows.

How it works

Paste your existing prompt into the input field and click Process Text. The tool returns a hardened version that keeps your original goal but adds clear security boundaries, including untrusted-input handling and priority-based conflict behavior.

Why prompt hardening matters

Prompt injection can happen when a model receives malicious instructions inside user messages, files, links, or retrieved documents. A hardened prompt reduces the chance that these instructions override your intended behavior.

Common use cases

• Support assistants that process user text
• Retrieval workflows with external context
• Structured extraction prompts for documents
• Internal AI tools that handle mixed-trust data

Output behavior

The output preserves your original task and format requirements, then adds security rules to isolate instructions and protect sensitive information. You can copy the result directly into your AI chat workflow.

Tips for best results

• Paste the full prompt, not a partial snippet.
• Keep existing format constraints in the input.
• Re-run hardening after major prompt changes.
• Validate behavior with benign and adversarial test inputs.

Use the result

After processing, copy the hardened prompt and use it in your AI app. This gives you a stronger baseline against prompt injection without redesigning your entire prompt from scratch.
