I’m looking for an app or service that automatically redacts/anonymizes fairly large numbers of files for use with LLMs. A colleague recommended an app called Curtain, found here [GitHub - cevdetcancetin/Curtain: Curtain — Support, Privacy Policy & Terms of Use · GitHub](https://github.com/cevdetcancetin/Curtain) because they know the developer. Has anyone used it? And, any other one you can recommend?

What’s the primary usecase? Development, accounting? Current tools sandbox the agent, and when an LLM calls for a credential, sandbox swaps the placeholder with a real credential by injecting it mid transit. You just have to have some kind of secrets management in place.

Oh wait, this is a fishing post
