I'm working on a reading app. It integrates llms with your content. I know that the current llm providers already help you upload and ask qs about the docuemnt.
But I'm focused on building a good reading experience overall - which helps you learn and understand the content more easily. Imagine Macos preview integrated with llms. Currently, the web app uses the llm apis but eventually will add support for local llms as well.
I'm aware of other apps that have done something similar, but want to see this through for myself.
