A tool for peer-to-peer thinking

Your Sekund brain

Sekund is a SaaS and an Obsidian plugin that let you share your notes and collaborate with others without leaving your beloved thinking environment.
Upload & Share

Want to get feedback on a note? Hit 'Upload to Sekund', then 'Share', pick people or groups, and you are done.

Instant Notifications

Get instantly notified when someone shares something with you, or comments on some of your shared notes.


What good would be a notes sharing platform if you weren't able to discuss? And Sekund's chat supports Markdown, of course.


Whatsapp-like groups allow anyone to follow through on specific topics.

Works Offline

Any shared note that you have opened is downloaded and saved on your disk, along with its dependencies.
