#SiYuan (with #Kmind) looks like a fantastic knowledge base manager.
"Refactor your thinking" and visualize it. You can host a public, read-only Wiki in Docker on your server.
I think it beats #Notion, #AppFlowy, #Evernote and #Confluence (for me). It also works without a cloud sync for free. The problem is that a proprietary tool here has many disadvantages besides the payment. The companies don't last long or change their products too much.
Some of the documentation is in Chinese, but I can read it or ask an AI tool to help. In fact, you can ask #DeepSeek or #qwen3 to help.
I now use it like #OneNote with a fast web UI and a public copy.

The plugins look interesting. Some may need a review. Like with #Wordpress .
