You've gotta do the slack-style growth strategy. Give users a free tier and market directly to end users. Let your users ignore their own company policy for their own convenience. Eventually they will end up dependent enough on it that their organizations will be forced to accept it.

Here is a fully self-hostable solution that connects to PDFs in your google drive folder: https://github.com/ai-sidekick/sidekick

Uses weaviate so that even the vectorstore can be self-hosted

Plenty of good open-source options https://github.com/marqo-ai/marqo/blob/mainline/examples/GPT... . LLM choice is a bit harder but the composability of it all lets you easily choose alternatives.

I also will not upload a proprietary document to this service. But mine and many other organizations do upload proprietary documents into third-party clouds (e.g., Azure, Google).

You might not dump your internal documentation or confidential files to it, but I can see something like this being very useful if you can chuck a user manual for a product into it and ask common-sense questions about the product. So many parts these days come with a multi-hundred-page, questionably-written manual that technically does contain all the required information but buries it in waffle.

There are various degrees to self hosting: for nice outputs, you need OpenAIs APIs to generate at least the answers. There are alternatives, but not as good.

If you are interested in this, feel free to reach out to me and I can help you with setting this up.

This seems vault-ai based which has instructions to self-host:
