Then the smartphone came and took over, and there was no good wiki-app and in the browser didn't really work. Since then I've switched to Evernote. Again more than 1000 notes without transferring the wiki to Evernote. I can get lost sometimes, and then it needs some work to clean up tags and notes.

I don't understand your problem. Evernote can be sorted on date of last access, so you always see the most recent notes on top. You don't want a collection of notes, but you want auto-archive? Isn't auto-archive the collection?

In evernote and probably any note taking app you can open a new note and start clean.
You create entries (called tiddlers) and you can hide them. Then, you won't see them by default, but you can search for them.
You can also set it to show you a specific tiddler when you load the page.
There are too many things like folder structure, tags, and even the format of the note (plain, MD, rich) to consider during the note taking experience. There’s also an annoying separation between note editing and viewing.
