Hi all, this is my first question! I have been finding a lot of pre-processing tools to anonymize prompt data, but was wondering if anyone knew of tools that could be used in post-processing llm chat history files.

I want to conduct a study that strives to more easily anonymize the participant chat history so that when I receive it, it reduces PII risk.

another step I will need to add is just dropping chats that discuss personal health or rather summarizes chats that discuss topics of personal health? I really don't know, hence me asking here before just developing it on my own!
