Obsidian
Notes as plain Markdown files in a folder you own, linked into a knowledge graph, with thousands of community plugins. The app is free without limits, including commercial use (a paid commercial licence is optional). Sync is US$4 a month billed annually (US$5 monthly) and Publish US$8 per site a month annually. Because notes are just files, you can back them up anywhere and open them in any editor. The plugin rabbit hole is real.
