Obsidian with the (core) Daily Notes⁽¹⁾ plugin plus Jump-To-Date⁽²⁾ and Daily Note Navbar⁽³⁾ is a powerful combo for me.
Everything is still searchable (or can be fed into an LLM) since it’s all Markdown text files behind the scenes. (And I can type my thoughts much faster than I can write.)

Curious to know what you actually do with the notes, though. I've tried to get in the habit of keeping daily journals but it ends up being very much write once, read never. Maybe having some kind of fuzzy, semantic search or LLM would unlock their usefulness, but so far I don't find myself ever really using the things I write down.
Writing with a pen and paper is different from typing on a keyboard at. brain level.
I need to finish that research and write that blog post, apparently.
