When typing notes it would be nice to have some autocomplete support for faster typing.
TabNine is a generic AI driven completion engine that can predict completions even for natural language text (not just programming languages). I have used this extensively to write documentation in my IDE and it really helps a ton. It would be nice if this could be integrated with Obsidian.
Use an IDE like IntelliJ or VS-Code to write your markdown files. These have support for TabNine and can work on the same directory structure as Obsidian.
