Are there any websites or resources analogous to Detextify for maths?
Presently, I do not know (but desire to learn) how to type Chinese characters.

  • If you're on a Mac, you can use the Stroke keyboard to draw characters and have computerised predictions appear.

    In general the Chinese input method supports handwriting.

  • If you have to rely on websites with handwriting (mousewriting) input, I also recommend mdbg.net. It loads faster than the nciku (line) dictionary, at least if you’re in Europe.

There are many online OCR input websites. For example:

http://www.yibizi.com/html5/ (neat and fast, without ads, but seems only working inside China)

I strongly suggest you install a client software rather than using a website because many websites are full of ads. And many of them are only working in some particular browsers, like infamous IE series.

Sougou Pinyin (wikipedia page) is the most used Input Method in China. I am also personally using this on my MacBook Pro. It has Windows/Mac version. You can get the software by clicking the links in the Wikipedia page.

With it, you can click "手写输入" to input by "drawing":

I use this one: http://ce.linedict.com/dict.html#/cnen/home and it always worked perfectly. Can recommend!

  • But this is a dictionary?

  • @Timere He meant the site supports handwriting. (Click the write icon on the left of search icon.)

The three best options IMHO are:

  1. Nciku (the pioneer, still works on a webpage). Now called Line-dict.
  2. Google Translate App, as posted above. It recently bought nciku's technology, but the imput method is not as confortable, since your writing must be really fast for the software to pick it up.
  3. Pleco: my own personal choice. It is flexible, extendable, colourful, confortable, has a very comprehensive dictionary, and has lots of extra features, such as automatic picture translation or even live video text translation (this last one function for a fee).
