💡 Frequently Asked Questions
How does manual bracket [ ] masking work?
Simply write any word or phrase inside square brackets like [John Doe] or [Secret Design Studio]. The tool automatically converts it into a safe token like [CUSTOM_1] before sending to AI, and restores the original word when you paste the AI reply back.
How does the Two-Way AI Prompt Anonymizer work?
The tool substitutes confidential names with structured placeholders like [PERSON_1] and [COMPANY_1] while preserving grammatical sentence context. Once ChatGPT generates the response, pasting it back restores the original names instantly.
Can AI providers see my actual client details?
No. The AI model only ever sees the placeholder tokens, preventing client data from being logged or used for future model retraining.
Does masking interfere with the quality of the AI response?
No. Modern LLMs understand contextual tokens like [PERSON_1] and [COMPANY_1] perfectly and will respond naturally using those tokens in the correct grammatical spots.
Where are the secret token mappings stored?
They exist only in your browser temporary RAM memory. If you refresh or close the page, the in-memory dictionary is immediately destroyed.
