Detexify is another one that&#x27;s been around for many years (at least 5 at this point) and has saved me hours: <a href="http:&#x2F;&#x2F;detexify.kirelabs.org&#x2F;classify.html" rel="nofollow">http:&#x2F;&#x2F;detexify.kirelabs.org&#x2F;classify.html</a>

On a somewhat related note, does anyone have any particularly nice ways of writing math-related notes?<p>Part of me wants to just hand-write them and then maybe scan them, but that&#x27;s not searchable&#x2F;indexable, and doesn&#x27;t lend itself well to version control.<p>Writing in TeX or LaTeX would make them searchable&#x2F;indexable, but this seems a little heavyweight for just notes (like answers to exercises). I don&#x27;t use TeX&#x2F;LaTeX that often, so I feel like I&#x27;d be spending half of my mental energy figuring out how to format things, figuring out how to invoke the tools, what packages to install, etc.<p>Are there any nice solutions out there for this sort of thing?

It works quite well, but I wish there was a way to make small corrections (e.g. erase parts of my input).<p>The app keeps mistaking my handwritten &quot;n&quot; for &quot;h&quot;, and my &quot;k&quot; for various obscure things like &quot;|x:&quot;, and it&#x27;s a bit of a pain to make small adjustments after most of the equation has been written: <a href="https:&#x2F;&#x2F;i.imgur.com&#x2F;KneVGIU.png" rel="nofollow">https:&#x2F;&#x2F;i.imgur.com&#x2F;KneVGIU.png</a>

Works like a charm on my Surface Pro 3. Incredibly impressed, One note doesn&#x27;t recognize my handwriting well but this is incredible as a math undegrad !<p>As many have said, an open-source app would be a godsend.

Awesome! This project reminds me of something I worked on years ago: <a href="http:&#x2F;&#x2F;goo.gl&#x2F;GKOxrg" rel="nofollow">http:&#x2F;&#x2F;goo.gl&#x2F;GKOxrg</a>

Very neat. One problem is immediate: when I handwrite an &quot;x&quot; for maths, it is as two &#x27;c&#x27;s touching back-to-back, so as not to confuse with some multiplication&#x2F;cross-product symbol; such input proves very confusing to this code.

I am building an Android (best with stylus) hand writing app...<p>Drawings can be viewed &#x2F; shared via web and are updated real-time (online whiteboard)<p>some samples:<p><a href="http:&#x2F;&#x2F;write-live.com&#x2F;d&#x2F;dba21681-8d3f-4fbe-8b4b-e5c1983df934" rel="nofollow">http:&#x2F;&#x2F;write-live.com&#x2F;d&#x2F;dba21681-8d3f-4fbe-8b4b-e5c1983df934</a><p><a href="http:&#x2F;&#x2F;docs.write-live.com&#x2F;WriteliveServer&#x2F;webview.html?d=2b81b4b1-af48-4a12-bab6-a7844eac91a5" rel="nofollow">http:&#x2F;&#x2F;docs.write-live.com&#x2F;WriteliveServer&#x2F;webview.html?d=2b...</a>

From what I can tell, it had a hard time distinguishing matrices from vectors. What I wanted was:<p><pre><code> [ 1 1 ] [ 0 1 ] </code></pre> What I got was<p><pre><code> [ 11 ] [ 01 ]</code></pre>

This would be quite a cool problem to attack using RNN. Perhaps using an attention-following mechanism like the one used for house numbers [1]. It&#x27;s fairly well-defined. You would need a ton of example data though.<p>[1] <a href="http:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;1412.7755" rel="nofollow">http:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;1412.7755</a>

Very impressive. It worked very well for me.

Pretty handy for someone like me who wastes a lot of time trying to get the Latex right in my R markdown docs.

awesome! how does it work? recurrent neural network?

This is actually pretty impressive<p>Tried it out on a random equation from the Fourier transform wiki page:<p><a href="http:&#x2F;&#x2F;imgur.com&#x2F;Ud9FNoA" rel="nofollow">http:&#x2F;&#x2F;imgur.com&#x2F;Ud9FNoA</a>

Nice! I can&#x27;t wait to try it on my touch screen PC.

LaTeX is super cool for mathematics and academic papers. For my book though I had to migrate off to InDesign because it was just much easier&#x2F;quicker to get it to do what I wanted.
