I came across a feature I liked very much on a platform to save important information, and saw the use case for better productivity with agents/assistants.
A centralized place to store information, that is not bound to variables inside an agent.
I see this being a good feature when chatting with an agent (just typing # to pull up saved information).
We have noticed interest from client based businesses, like lawyers, accountants to have saved information about their clients, so the questions to the LLM's become more relevant, without having to type or copy/paste each time.
Take a look at how copy.ai solved this by their feature (infobase: https://www.copy.ai/blog/infobase-by-copyai)
