That divider with a time stamp on the right is very cute!

I am looking for, in a sense, the opposite of this app. I need an AI-powered IDE-like editor for markdown files. I keep a ton of research notes in markdown and when it comes to writing reports for admins and such, I need something to help me make sense of them, integrate them, reformat, do a "semantic refactoring" across files, diffs. etc. I saw people use Obsidian with some plugins, but I think I need Cursor for markdown. Any suggestions?
