Prompt Boundary & Delimiter Builder
Wraps user or RAG text in generated delimiters and produces a template that tells a model to treat enclosed content as data, with allowed and forbidden behavior. It does not stop prompt injection by itself.
✓ Free✓ No account✓ In-browser
Persistent storage
Input and output are not stored. The optional usage counter keeps only tool identity and count, never content.
Verification
Output comes from disclosed rules or browser APIs and needs independent review before high-impact use.
A result in three steps
- 01
Paste the content to process.
- 02
Generate the local template and review its boundaries.
- 03
Test separately with role separation and allowlists on the real model.
When is this tool useful?
- ✓ Separating RAG content from instructions
- ✓ Isolating user text as data
- ✓ Standardizing prompt reviews
Important limitation
Automated output is a preliminary assessment. Do not use it alone for legal, financial, medical, or security-critical decisions.
