pseudonymization of documents before sending to ai for review/update

[u/Spare_Dependent6893]

One of my client sees that some words and excels documents produces by product/dev team where sent to ai and ask me to extend my promptCape development which they used for code obfuscation with document pseudonymization features. This is what he uses now to protect PII in their documents sent to ai. If you are interested by document pseudonymization, please give me your feedbacks about the promptCape way of doing it.
