Would an app that helps you prepare for difficult relationship conversations be useful?

I’ve been thinking about how many relationship issues comes from poor communication – especially those moments when you know something’s bothering you but you can’t figure out how to bring it up without starting a war.

I went with my wife over many rounds of such conversations and I think I made some experience on how to go trough them in respective manner and how to prevent potential blame-spirals to kick in.
I was wondering about making a web app that would help guide you and your partner trough challenging topics making them easier to discuss, basically:
1. You describe what’s bothering you in a guided form
2. The app helps reframe your concerns in a less accusatory way (like changing “you always leave dishes out” to “I feel overwhelmed when kitchen cleanup falls mostly on me”)
3. It gives you conversation starters and tips for staying constructive

The goal isn’t to script the conversation, but to help you go into it feeling prepared and calm instead of reactive and emotional.

I’m curious – would something like this actually be helpful for you guys?

Let me know your thoughts and ideas on this topic please
