I built an AI roleplay partner for rehearsing hard conversations. Where does it fall short?

I'm Anton, founder of Talkasu (https://talkasu.com).

It's for the conversations people avoid or blow: asking for a raise, saying no to a boss, setting boundaries with family, getting a kid to listen without yelling, repairing after a fight. There are 13 short trainings. You practise against an AI counterpart that stalls, deflects or gets defensive, and you get clearer wording to try next.

It works on the web and on Android, and it's free to start with free daily credits (there's an optional subscription).

What I'd love blunt feedback on:

1. Does the first training make sense within a minute, or is onboarding confusing?

2. Does the AI's pushback feel realistic or too soft?

3. Which conversation would you actually rehearse, and is it missing?

A good one to try first: https://talkasu.com/en/trainings/ask-for-a-raise
