Common questions
How do I use LaTeX math in articles?
Wrap inline math in $...$ and display math in $$...$$. The editor renders KaTeX live as you type.
What's the difference between an article and a book?
Articles are standalone pieces. Books are collections of chapters you can build incrementally and share as a whole.
Can I import from other platforms?
Markdown files with standard frontmatter can be pasted directly into the editor. LaTeX import is on the roadmap.
How does access control work?
Each resource can be set to public or private. Private content is only visible to you and your organization members.
Is my content permanently mine?
Yes. You retain full ownership. Deleting your account removes it from the platform, but we recommend exporting first.
What browsers are supported?
All modern browsers (Chrome, Firefox, Safari, Edge). The editor works best on desktop for complex formatting.
Why is my animation not rendering?
Animations use a custom syntax. Check the animation reference docs for supported parameters and types.
