New feature: Documents - maybe a whole new product?

I frequently have to work on long complex boring documents usually related to compliance or governance. Naturally I reach for T3 chat to help me research and write these documents. The problem I run into is T3 chat is not designed for this, it is for having a discussion with llm’s. It does however already have most of what I need. What it does not have is the concept of a document that I can instruct an LLM to interact with and also I would like to be able to invite others to collaborate with me.
I have had a go at vibe coding this and I got something working but I don’t really have the time to turn it into a polished solution with all the features I want.
I’m interested to know if this use case is a common one that would be relvant to lots of people. Personally I would happily pay an extra $6 a month for this as it would save me a ton of time.
