Show HN: Clozemaster – Learn language in context

Hi Hacker News! My name's Mike. I'm the creator of Clozemaster.

Clozemaster is language learning through mass exposure to vocabulary in context. The goal is to fill in the missing word in a given sentence. The missing word is the most difficult word in the sentence according a frequency list for that language, and the sentences are from the awesome dataset at Tatoeba.

I started the site just under a year ago to answer the question "what should I do after finishing Duolingo?". Since then it's grown to support over 50 languages, mobile apps, and thousands of users. It's useful for learners at almost any level, from beginner to advanced, and makes a great complement to Duolingo, textbooks, classrooms, etc. to practice vocab in context.

You can play the Fluency Fast Track which gives you a sentence for each unique missing word in order of increasing difficulty, jump in to sentences grouped by frequency from the 100 most common words to the 10,000 most common, or just play random sentences. There's also "cloze-listening" - hear the sentence first, then see it and fill in the missing word.

Thought Hacker New might find Clozemaster interesting and hopefully useful! It's still very much a work in progress - I have a bunch more features planned and I'm working to improve it all the time. I'm also open to any feedback and happy to answer any questions!

This is much better than duo lingo. Amazing job!

Substitute a word requires certain language knowledge. This should be tested somehow, so that the application knows the user level. For example, having no prior Spanish knowledge I would not do substitute a word, and i can do listen exercises which show me some common words and already teach me something. This was enjoyable... for the first 3 minutes.

After just one run and 3 minutes into the registration it already is asking for money? I have no problem paying when I see what I'm paying for. Here I had too little time to see, and already am annoyed by this. So cloze-listening is already unreachable for me, and I would not play the other game without having any language knowledge. Fail right here.

Learning a language is a task for months, you'll (the author) be very safe asking for money after several days or even weeks of trial.

There could certainly be multiple answers that make sense like you mentioned, though at the moment only one answer is accepted by default. There is however the option to add your own alternative answers, http://imgur.com/a/Vl5o4, and I'd definitely like to come up with some way to support multiple default answers in the future.

Thanks for the feedback! Agreed on both points. I'm aiming to revamp the landing page within the next few months, definitely needs some work.
