Show HN: Supernotes – The Social Notework for collaborative knowledge management

Hi HN, I'm one of the (two) makers behind Supernotes. We first started building Supernotes when we were in college and wanted a way for students to more easily share learning content with each other in a granular way. Once we actually built our solution, we realized that the use-cases reach far beyond students and that our unique features work well for anyone that wants to do (semi-)social knowledge management.

Quick overview of what makes us different from some of the other great tools in this space: 1. Built around cards rather than documents, which allows for a lot of interesting and flexible features. 2. Granular sharing – on Supernotes, you can share an entire collection of cards, or you can share one card at a time. We also have recently introduced a "friends" features that allows you to quickly drag-and-drop cards onto your friends to share with them. 3. Multi-parent nesting – there is no folder-style filesystem on Supernotes, we allow you to nest cards inside of each other. On top of this, we allow for this nesting to be multi-parent, so different users can fit the same cards into their own unique structure. 4. Public vs. private tags – cards can be tagged with public tags that everyone sees, but can also be tagged privately with only tags that you can see. This same idea is reflected across the platform, where we want the underlying content to be the same for everyone but want to allow users to personalize the metadata/structure to suit their own workflow. 5. Focus on speed – we have spent a lot of time making Supernotes speedy quick, and try to make it faster every time we release a new feature.

We also have lots of the cool features that are shared by other products, such as: - bi-directional inline links - markdown / LaTeX / code-highlighting support - many more

...and are releasing new features every month[1]!

Happy to answer any questions you might have.

Your website looks awesome, and I think this is a great product. I've signed up. What software/languages/tools did you use to build this?
