# Curio

Curio is a visual brainstorming and note-taking app that can stream the item you are editing into Marked’s streaming preview channel.

## Stream Selected to Marked

1. In Marked, choose File New Streaming Preview so a streaming preview window is ready.
2. In Curio, turn on View → Stream Selected to Marked.

When you double-click to edit a figure, note, list, or other item in Curio, its Markdown flows to the streaming preview and updates as you write.

Marked updates in near real time, following the same `mkStreamingPreview` clipboard contract as other integrated apps—see Technical details under Streaming Preview.

If previews stop updating, confirm a streaming preview window is open in Marked and toggle Stream Selected to Marked once in Curio.
