Any language learners out there?

I welcome you to try out a language learning platform I'm developing. I just released the alpha at https://omoide.app. It exclusively uses speech synthesis and speech recognition for exercises, so you learn by speaking and listening. You must have a mic and a modern browser. You add your own content, similar to Anki. Supports 8 languages but I haven't had time to personal test all of them, so please let me know of bugs! Try for free today, no login required. Would love to hear feedback!
