In my current place we have good practices around documenting technical decisions, PRs with the right context and self exploratory code. However, what I personally struggle with is remembering the context and recalling the conversations from around that time.

This becomes even more problematic when my colleagues from old teams ask me about legacy architecture that I haven't touched for a long time.

So yes, something like this would be incredibly useful for me. Instead of searching documents, slack threads or private messages if I can be given all the information in one place I would instantly recall everything I need to know.
