The data is used for symbol classifier which was provided by the HWRT database of handwritten symbols.
Method to train data is followed by Martin Thoma in his paper

For Bibliography/Cite we are using libraries:
- citation-js: https://github.com/citation-js/citation-js
- citeprocjs: https://github.com/Juris-M/citeproc-js
- CSL Styles: https://github.com/citation-style-language/styles

And multiple opensource libraries...

We want to help people to quickly write any mathematics formula/equation. People don't need to know about LATEX, but still have a powerful and rich Mathematics symbols/layouts/features so they can share with others.

Other tools allow you to insert some mathematical symbols, but it's slow when you want to add something like square root or fraction (you need to move your mouse to click and select), and only support Math Mode, there is no mix between Math Mode and normal text (Text Mode)

This tool provides sufficent Normal Text Editing Feature, and various sets of mathematical symbols/layouts, together with Drawing Features, which helps you to have a single place to create your own Mathematical document (Normal Text, Math Mode Text, Diagram/Graph).

This one is not meant to be a replacement of Rich Text Editing (Google Doc, Microsoft Word, ...) its goal is for inputing Mathematics.
