Try PII masking before your prompt reaches AI.

Paste a prompt, choose reversible or irreversible masking, and compare the output. Sample previews illustrate detection; live API results show the returned text.

Waiting for prompt
Not run yet
Write your prompt or choose a sample, then press Mask prompt.

Raw prompt

Use fictional data only. Built-in samples run locally. Other inputs are sent to the NeutralAI gateway when you press Mask prompt on the hosted site; this playground does not send them to an AI model.

Detection details

Local previews use illustrative pattern matching, not production detection scores. Live results do not include entity details in this playground.

0 preview matches
Choose a sample to explore illustrative entity matches. No matches is not a safety guarantee.
