More room to think.

From a passing thought to a project taking shape, Orange Cat keeps your words at the center. A native notebook, with the tools you need right where you need them.

Just you.
And your words.

Write in Markdown and see your ideas take shape. Keep the preview beside your draft, focus on the source, or settle into reading.

Markdown source and preview in Orange Cat

A blank page.
Or a head start.

Some ideas need an open page. Others need a little structure. Create your own Markdown templates and choose how every new note begins.

  • Start blank or use a default template
  • Create and edit your own templates
  • Insert a template anytime while editing

Your structure.
Right where you need it.

Add a template at your editing position, keeping the rest of your note. A meeting agenda, a project outline, or your next idea can begin right in the middle of the page.

Good ideas evolve.
Keep their story.

Save a revision when it matters. Let automatic revisions catch meaningful changes along the way. Then look back and see exactly what changed.
