## Clean and modern look
Zefyr's rich text editor is built with simplicity and flexibility in
mind. It provides clean interface for distraction-free editing. Think
Medium.com-like experience.
## Markdown-inspired semantics
Ever needed to have a heading line inside of a quote block, like in
this Markdown block:
> ### I'm a Markdown heading
> And I'm a regular paragraph
Zefyr can deliver exactly that:
## Ready for collaborative editing
Zefyr's document model uses data format compatible with
[Operational Transformation][ot] which makes it possible to use for
collaborative editing use cases or whenever there is a need for
conflict-free resolution of changes.
> Zefyr editor uses Quill.js **Delta** as underlying data format. Read
> more about Zefyr and Deltas in our [documentation][data_and_document].
> Make sure to checkout [official documentation][delta] for Delta format
> as well.
