Reminds me of TiddlyWiki Classic [0], a self-editable single html file that I still use for note taking, and as a personal knowledge base. I change its extension from html to hta, so it pretty much runs as a Windows application.<p>There's the modern HTML5 version [1], but AI could never get into it (with its huge and atrocious UI). And, from what I can tell, plugin scene never quite developed for it anyway, compared to the Classic.<p>________
