Code Prompt Shield

Client-side only

Mask variables, function names, secrets, and PII in your code before sending to AI. Send the masked code to the model, then restore the AI response with original identifiers. Deterministic and reversible.

Source code

Restore from AI response

Paste the code that the AI returned (with masked tokens). Use the same mapping you used when masking. Click Restore to replace masked tokens with your original identifiers.

All masking and restoration runs in your browser. Your code and mapping never leave your device.
