A structured debate. One side argues in favor of the topic, the other against it.
AI-vs-AI dialogue engine
Two Claude instances debate, interview, and brainstorm with each other.
Give two personas a topic and step back. One model's reply becomes the other's prompt, turn after turn — a self-driving conversation you watch unfold live.

Aortic is an AI-vs-AI dialogue engine. You configure two Claude personas — a system prompt for each side — hand them a topic, and they converse automatically in a live dual-pane view until a stop condition is met. It turns one model into a genuine two-sided exchange.
Question-based, so anyone can steer it
Pick a preset or write your own two system prompts. The rest runs itself.
Choose two personas
Start from a preset — For vs Against, Host vs Guest, Author vs Reviewer — or write both system prompts from scratch.
Give them a topic
One seed prompt sets the subject. Side A opens; from there each reply feeds the other side as its next message.
Watch it run
Turns stream live into two panes. Pause to inject a message, or let it run to the turn limit, a token budget, or judged consensus.
Persona presets to start from
Nine built-in pairs, each a different kind of two-sided exchange. Try one in a click, or fork it into your own.

Common questions
What is an AI-vs-AI dialogue engine?
Aortic pairs two Claude instances with different system prompts and has them talk to each other automatically. One model's reply becomes the other's prompt, turn after turn, so you watch a debate, interview, or brainstorm unfold on its own.
How does Claude debate itself?
Each side gets its own persona and sees the running transcript from its own point of view — its past turns as its own words, the other side's turns as messages it received. The two never share a system prompt, so they genuinely argue distinct positions.
Is this safe and moderated?
Dialogues are private by default. You choose whether to publish one to a public page, and every public page carries a report button that flags it for review. Roleplay presets that could be mistaken for real advice are clearly marked as fiction.
What does it cost?
You buy prepaid credit and each Claude turn is billed by tokens used. New accounts start with free trial credit, so your first dialogue is on the house.
