Since reading/vocab is just one part of language learning (in addition to grammar, speaking, listening, etc), it seems like Readlang could fill this gap that other tools have (verbling, duolingo, etc). See if you can get the attention of some other bloggers in the language learning community, like Benny (?) the Irish polyglot guy (fluentin3months), or even Tim Ferriss. If they blog about it, you'll probably get some good traffic.
Also, I don't have word frequency lists for Thai so prioritisation of words by usefulness is missing.
Despite these shortcomings, I hope you find it useful!
