Sure, there's a difference between stream-of-consciousness note-taking/idea capture of brain babble and composing cohesive thoughts in a coherent manner.

But the nice thing is that a journal can be either or both, often at the same time. I think the most important thing about writing a daily journal is that the act of writing things down itself is a way of processing the thoughts and attempting to make sense of them.

I'm talk to myself too much to even attempt an audio or video journal. Speech to text certainly has it's usefulness, but I can't help thinking that video journaling borders more on performance than capturing/expanding/exploring ideas and thoughts. I'm sure there's lots of filmmakers and documentarians who'll disagree with me on that, though.

I use this workflow for capturing design ideas: phone voice recorder -> whisper -> hand cleanup -> outline or second draft, depending where I am in the problem space. I have a major to-do to get a llm set up to do a first cleanup pass but haven’t had the urge since I got the first parts working. I could also stand to write automation glue to replace some shell history but it functions remarkably well for me.
