Why this is different from asking an AI assistant
Standard AI assistants agree with whoever is talking to them. If you describe a conflict, they validate your account of it. The other party — if they described the same situation — would receive the same validation in the opposite direction.
Common Ground is designed from the opposite assumption. Its purpose is not to make anyone feel heard in the sense of feeling agreed with. It's to hold the whole situation — both accounts, both perspectives, the gap between them — and work honestly from there.
That means both parties can trust it. Neither is disadvantaged by who arrived first, who writes most fluently, or who sounds most certain. Common Ground is not a tool for winning an argument. It's a space for resolving one.
