Show HN: A note-taking app that helps you to study your notes

Hi,

To sum up, this app is like the combination of Evernote and Quizlet.

Here are some features:

- It is offline-first. The notes are stored in a local database for offline access.

- Support writing Math/Physics formula and chemical equations.

- Syntax highlighting for writing code block.

- Support image occlusion for learning Biology, etc, ...

- Support cloze deletion for active recall.

- Free drawing (hand-writing).

Technology-wise, this app is built using React and Typescript with Electron. And I built it using Vim editor only.
