Dynamic Context
As you write and move your cursor, Koubou automatically tracks context that can be used in prompts:
| Variable | What it captures |
|---|---|
{{lastParagraph}} | The paragraph containing your cursor |
{{lastSentence}} | The last sentence before your cursor |
{{selectedText}} | Any text you’ve highlighted |
{{currentHeading}} | The nearest heading above your cursor |
{{sectionContent}} | Content up to the previous horizontal rule |
{{h2SectionContent}} | Content up to the previous H2 |
This makes your prompts context-aware without copying and pasting.
Output Options
When creating AI content, you can choose:
- Stream to Main Editor — Content streams directly into your open document. When this of off the content instead streams to the right panel so you can work “beside” your main document.
