Import OPML outlines into TreeNote in minutes and export them when you need to. Keep your hierarchy, notes and checkboxes portable.
Export one branch or your full outline from a compatible tool, then choose Import → OPML in TreeNote. The imported file becomes a new document, leaving the original account and outline untouched.
A branch you are working in this week tells you more than the whole archive, and it takes a minute rather than an afternoon.
The file arrives as its own document, so there is nothing to merge and nothing at risk in what you already have.
Use it for a few real days before deciding. Your original outline is still exactly where you left it.
OPML gives your outline a format that can move between outliners. TreeNote also provides JSON backup for a fuller copy of your TreeNote workspace.
Import a real outline into TreeNote today. Your original stays unchanged, and your work stays portable.
Try TreeNote today on your own machine. Your outline is stored locally and stays completely private.

Sync your TreeNote workspace across devices with your own Google Drive or Dropbox account. Keep your outline current while your files remain in storage you control.
Write markdown. Click away. Read it.
Type /md in TreeNote to turn an item into a markdown block. Write headings, lists, quotes and fenced code inside one item, then click out and it renders as formatted markdown.
