If you want to be able to get into the nitty gritty or play with options besides just a chat, I recommend Text Generation WebUI.
Installing is pretty easy, then you just download your desired model from Hugging Face.
Or if you want to use it for roleplay or adventure style games, KoboldCPP is easy to set up.
Surge is probably the easiest way to get a basic setup. If you just want to download a model and chat, I recommend it.
I wouldn't say barebones, but you're right in there is no direct alternative to OneNote I have ever found. It remains the product I haven't been able to directly replace.
A lot of the products people will suggest are very feature rich, just not all the same features as OneNote. For me, the ability to draw on the page freestyle with a stylus is what I love about OneNote. So easy to annotate notes. But linking and plugins are things others have which I love that OneNote lacks.
Logseq has a "whiteboard" feature which is the closest I've seen.
OneNote has been the only tool Ive failed to find a close alternative to, which is a shame because I hate the new simplified versions of OneNote.
I will say though, the linking available on Obsidian and Logseq is fantastic for d&d notes and worth ditching OneNote anyway (for me it was at least).

How people can fuck up writing "yes" or "no" in a single box is beyond me

Sonarr dark mode! Finally I won't be blinded when I open it to try and fix a series at 1am.
