Private AI for small law offices.

I've gone down the rabbit hole with local LLM's and believe there is a potential use case for small law firms. The service/product idea is being able go into a small law firm and index all their historical and future case info with RAG and fine tune the private LLM. After this is done the lawyer can now ask questions about historical and new case data. Let's say this is family law, he/she can ask the LLM to give him a list of all cases with custody summaries with certain judge. I'm thinking the ability to be able to search your own case data for research purposes would be a powerful tool? There are other tools out there but they are not private like this.

Sound crazy?

Thanks!
