Well done! I have built a side project in the same space given that i wanted to learn Spanish (my wife is Colombian) and also wasnt happy with existing offerings. I have used the OpenAI realtime API to fully focus on audio conversations. You can check it out (for free) here: http://lucas.alldone.app/
Yes thanks and makes sense! I should try that again.
I had a video live for a few days but the conversion rate from visiting the homepage to downloading the app actually went down ... but maybe it was the quality of the video and I should try again
