I’d use AI for a number of reasons, all including chaos and chance; I wouldn’t use AI to write or change my Obsidian notes but rather to provide at least one different perspective.

I use Obsidian for different purposes:

• my digital garden, handled via a plugin and GitHub
• technical writing: I work as a tech writer so I use Obsidian for research and to review my writing against a number of frameworks and style guides
• create presentations: nothing spiffy, mainly using the built-in presentation functionality
• note-taking in meetings: I take notes of everything, from screenshots to screencasts to audio. Everything is searchable through the Omnisearch plugin
