## What is CardNotes?

The Perfect Tool for Zettelkasten!

The first handwritten note-taking app that supports Bi-directional Linking

We are all fond of handwritten notes and believe that handwriting can help us take better notes and think smarter.

CardNotes has made a breakthrough in adding Bi-directional Linking to the handwritten note-taking app, so that every note and knowledge of yours is no longer independent, but is constantly interlaced and connected like our brain nerves to generate new ideas.

Our future direction will focus on making your knowledge better connected, helping you learn better, and being able to truly internalize knowledge from books or other sources to become a better version of yourself.

We are convinced that notes should not be independent of each other, but rather linked because:
1. If each piece of knowledge is too independent, just like when building a building, every floor is rebuilt on the foundation; if you want a building to be built high enough, you need to build a higher floor on top of it Above; knowledge is the same, when you learn new knowledge, connect it to existing knowledge, you can make your knowledge more consolidated in your brain, and you can take yourself to a higher level.
2. Innovation is often the combination of old things
3. Knowledge Links can help us revisit old notes instead of turning them into "decorations".

We love handwriting because:
1. Unfettered
2. Research shows that handwriting activates more brain regions than typing
3. Feel warm

**** Special Functions ****
・The first handwritten note-taking app with Bi-directional linking

****IMPORTANT: PRIVACY****
All notes will only be saved on your device (with iCloud sync support in the future), we will never read any of your notes.
