Supertags
In addition to marking tags in card notes, you can also write your own thinking summary on the supertag detail page.

This is a note that has been processed and understood by you. It has two meanings:
- Summarize your current understanding, which can help you build a more systematic knowledge structure.
- Provide basis for AI understanding. When AI generates content, it will refer to what's written here.
Of course, you can also use the "note assistant" feature in this section.
Also, always remember when writing: everything should center on your own understanding.
