buiducnha··on I draw figures for my mathematical lecture notes using Inkscape
1. Export types:

- Export to Latex (Mostly for Math Mode, and does not guarantee compiled in complicated case)

- Tikz (for Diagram)

- MathMl (Math Mode only)

- SVG/PNG (Math Mode and Diagram only)

- Save as Html (.zip file)

- Save as PDF (currently supported on Desktop version), but you can use Browser Print and save as PDF

2. Sorry, I don't have clear Road map, mainly I'm working on to add more features specifically on Math (for example Z Specification)

3. Unfortunately there is no one-time payment license now.

I've just checked LyX, actually it's quite good and similar to Mathcha, but actually it serves different goals/features than Mathcha.

- LyX: full Latex compiled, and Mix between WYSIWYG and Latex Script. Mainly use to create Latex Document

- Mathcha: can export some parts to Latex (mostly Math mode) but does not guarantee to compile, a full WYSIWYG editor. The goal to just create Document without constraints to Latex format

I've also read previous article about how the author manage to take lecture note using Vim+Latex (also posted on HN), and that's amazing how author managed to do that. But I'm thinking for people who does not know how to use Vim (arguingly high learning curve) and Latex to take note, what options do they have to take note quickly (with Math symbols/layouts)?

You can try out Mathcha[1] which is built to help people without knowing of Latex can easily write down Note (with rich Mathematics symbols/layouts) and it also provide basic Drawing and basic Function Plotting (The Drawing Part no way compare to Inkscape, but hey! you can type Math on Drawing on Mathcha) in single Editor.

Please note that I don't want to tout and advertise Mathcha here, the point is to provide another option for people to try out (I will not say it will provide faster or more powerful than Vim+Latex)

Thanks, sorry for that bad English :)

The reason is we did not test carefully on Edge, may have some problems we don't know!

1. You can export diagram as Image (PNG), by selecting Diagram itself (not item in Diagram), and click "Save as Image" on toolbar (resolution will be doubled as normal). There is no Vector Format Export.

2. Will have a look at TikZ format

Thanks

Very good point, did think about that, but until now still not very sure about business model. At the beginning, when we build it, we want to have a editor for people to easily type and share their Math (even without knowing LATEX). Will definitely consider/think about Integration, or somethings else ...

Thanks.

It's free to use, currently there is a limit of 50 documents (to avoid people create unlimited documents), will increase that limit.

Hi, that's intentional, because we see that most of the time superscript input is only one character, you can press arrow left to go back and input more characters.

Maybe in future I should have a setting to turn off that feature/behavior.

Thanks.

With Inline Math (\inline-math), there are some symbols will be displayed smaller (by default) than Display Mode (math-container). This is because I implement it to be the same with LATEX style, maybe most of people dont want that behavior, so may possibly change in future.

Good advice on MIME types, thanks.

Thanks for feedback, did not aware of different type of keyboard layouts!

Hi, I submitted again because at that time I did not know and did not post with Prefix "Show HN:". Maybe that's reason?

Yes you can export to LATEX (Math Mode only), you even can import from Latex (still only for Math Mode). It support most of LATEX commands (not TEX and advanced commands like macro..)

We may support exporting to LATEX in Text Mode in future (if people really need that feature)
