Disagreement is a skill
Most platforms try to eliminate conflict. We think that's a mistake. The best ideas, strongest relationships, and clearest thinking come from learning to disagree well.
Our mission
Better conversations, better outcomes
Disagree.ing is built on a simple belief: when people engage with opposing views honestly and thoughtfully, everyone benefits. We use AI not to replace human dialogue, but to make it more productive.
Whether you're stress-testing an argument before a big presentation, working through a disagreement with your partner, or just exploring the other side of an issue—we give you the tools to do it well.
Challenge, don't confirm
Our AI is designed to push back, not agree. You'll encounter the strongest version of opposing arguments.
Empathy before solutions
In mediation, our AI listens first. Both sides feel heard before any resolution is attempted.

The story
Built by UpNorth.ai
Disagree.ing started from a frustration: online discourse is broken. Social media rewards outrage, not understanding. Comment sections devolve into shouting matches. Real disagreements between real people go unresolved because there's no good tool to help.
We realized AI could change this. Not by taking sides, but by being the opponent who makes you sharper, and the mediator who helps both sides find common ground. Claude—Anthropic's AI—powers every conversation on the platform, bringing nuance, empathy, and intellectual rigor.
Disagree.ing is built and maintained by UpNorth.ai, a studio focused on AI-native products that make people better at what they do.
