Needs more attention. Anything that replicates ChatGPT using OpenAI APIs is valuable because of this fact for enterprise use cases.
https://mitta.ai uses these API calls, has an Open Source code base for inspection, a strong user privacy policy, and doesn't store data in transit, other than documents that are uploaded. I'm working on TTLs for the files stored, so there is no data left behind (other than what might be stored by the user in the DB).
