Would you use an AI to rehearse important conversations?

I've been working on something a bit different from typical AI tools. Most AI helps you generate answers. But in real life, what actually matters is how you perform in conversations. Interviews, sales calls, tough discussions, important meetings - you don't get to "edit" those.

So I'm building KailaOS - an AI assistant focused on helping you practice. You can:

• simulate real conversations
• try different responses
• get feedback on what worked and what didn't

The goal is simple: show up more prepared. I'm still figuring out if this is a real problem or just something that sounds useful.

Curious:
When was the last time you wished you could rehearse something before it actually happened?
