A link in a few clicks
Shape the public version before it leaves.
Give the page a clearer title, add an introduction, and choose whether visible note properties belong in the shared version.
Sharing Notes
Share the note. Keep everything else private.
Turn any note into a clean public page with one link. You decide what readers see, when the page updates, and when it disappears.
Publish simply
One read-only link
Update deliberately
Sync when you are ready
Stay in control
Expire or unpublish anytime
From private draft to public page
Share the finished thought, not the workspace around it.
Sharing lives beside the note, but the result is made for the web. Publish only the writing and context that belong, while the original stays in your local workspace.
Made for reading
Publish a page, not an editor dump.
Markdown, images, and the context you choose arrive in a calm reading view with space for the writing to breathe.
Your reader, your way
Set the defaults once.
Choose light and dark themes, heading and body fonts, attribution, properties, and expiration defaults for every new share.
Public on your terms
The link changes only when you say so.
Keep editing the private note after it is shared. Readers see the last version you published until you sync again, and you can close access without touching the original.
Shape the reading surface
Publish the title, summary, visible properties, Markdown, and workspace images that belong in the public version.
Choose how long it lives
Set an expiration for a single note or let an important link remain available indefinitely.
Stay in control
Copy, open, sync, or unpublish the link from the note or command bar without changing the private original.
Links that know when to leave
Choose a lifetime from 3 to 90 days, set a custom expiration, or keep a link available indefinitely.
Only show what belongs
Include useful visible properties while private Octarine metadata stays out of the public page.
A reader that feels like yours
Set light and dark themes, heading and body fonts, and optional author attribution.

Been using Octarine as my daily driver for the past few days and I'm impressed. Seriously considering jumping from Noteplan.

Oh my god it is perfect! Thank you so much!! I love how it renders the diagram under the definition instead of replacing it, perfect!! You have a user for life!

Started using Octarine a few days ago and it is such a beautiful app. Everything is just right — not too much, not too little.
