This is a long-shot but I use Memrise.com to learn/practice my kanji and it would be amazing if the fabulous sljfaq handwriting recognition tool could be integrated with it (and with any website that for some reason need this route to kanji input). Is there any way to do this now, or is it something that you might support in the future?
I searched this discussion forum and the web a bit and couldn't find any source code for the recognition engine, beyond the KanjiVG project---if the source was available I'd be more than willing to look into such an API for you.
Many thanks for this tool. It has *never* let me down, on desktop or smartphone (unlike my frequent attempts at using the built-in iOS traditional Chinese handwriting recognition for kanji).
