Prismical offers exactly the functionality I was looking for in an easy-to-use meeting transcription and note-taking tool.
It is super accessible since it covers all the big platforms, including mobile - robust and reliable.

What I'm really looking forward to is the roadmap: what's coming in the next few weeks will turn this into a truly comprehensive 2nd brain and knowledge hub with deep AI integration. I have used another product from this dev team before and was very impressed, so I am confident that their vision for the roadmap will be successfully implemented.
Happy that this was launched on AppSumo and I was able to grab it.
