I've just transitioned from Apple Notes to Obsidian and so far I'm loving it. In terms of high quality free software (not nec. OSS) it feels like the same league as Blender. It's so simple and so powerful.

I use it for ad hoc notes and research (e.g. project ideas, an ML-course I'm taking now, random interesting subjects beyond tech) as well as for daily journaling.

I start my day by writing in a "stream of consciousness" app I wrote for myself: https://enso.sonnet.io.

The format is as follows (ca. 20m each morning, 700-800 words):

- 100% unstructured description of my previous day, then

- 3-4 things I found beautiful or interesting, then

- a short TODO list for the day.

Then I just copy past the notes into my new daily note in Obsidian.

This seems to work really well for me. If I was to pick one improvement, it would be Apple Reminders treating multi-line text as separate entries when pasting. But again, it takes just a few seconds, and most of my workflow is just muscle memory at this stage.

PS. I'm thinking about writing an Open AI Whisper powered transcription tool for voice notes in Obsidian. If that's something you'd find useful and would be prepared to pay for, please let me know.
