I'm super excited to announce my new language learning AI startup: ISSEN. We have joined the YC F24 batch with my co-founder Anton, and are now releasing our app at After spending years learning Japanese from multiple teachers and apps, I realized that talking and immersion is the best way to learn. In the last year, AI models have advanced to a point where it's finally possible to create an amazing voice tutor experience, and that is exactly what we have been working on the last few months.

It's both effective and fun, and we are improving it every day. We would love to hear your thoughts about it! ( Also, checkout our launch YC Post:
