ONE QUESTION · MULTIPLE MINDS

More than multiple answers. A discussion.

Ask once. ChatRound lets leading AI models answer independently, challenge one another, and return a focused synthesis.

WHY A ROUND

You should not have to compare five chat tabs.

ChatRound turns several model outputs into one readable process, without hiding where they disagree.

Ask once

Start with one real question.

Select the models and context that matter. Every model receives the same prompt, so the comparison begins fairly.

Use disagreement

Make the strongest conflict visible.

In Discussion mode, models read the other answers, respond to the strongest objection, and revise when the evidence warrants it.

Leave with clarity

Finish with a synthesis, not more noise.

The moderator summarizes what converged, what remains uncertain, and which assumptions should drive the decision.

TWO WAYS TO ASK

Use the amount of collaboration the question needs.

Independent answers

Best when you want breadth without influence. Each model answers from its own perspective, then you compare.

Research · second opinions · fast comparison

Discussion

Best when tradeoffs matter. Models respond to one another and a moderator brings the strongest reasoning together.

Decisions · strategy · difficult judgment

PRICING

One subscription instead of three.

A turn is one response from one model. If three models respond twice each, that's six turns. The moderator's turns are free.

COMMON QUESTIONS

What people ask before their first round.

What it costs, what happens to your keys, and what the models actually do to each other's answers.

Is ChatRound free?

Three ways. Bring your own OpenRouter key or custom endpoint and it is free and unlimited — the service you connect bills you directly, with no ChatRound markup. Without a key of your own, the free plan covers 40 model turns a month, and Pro is $19 for 1,200 advanced turns and 8,000 basic.

What happens to my credentials?

Your OpenRouter key and custom-endpoint credentials are encrypted with AES-256-GCM before storage and sent only to the service you configure. You can remove them at any time.

Which models can I use?

Fourteen models from eight sources: OpenAI, Anthropic, Google and xAI, plus the open-weight DeepSeek, GLM, Kimi and Qwen. You choose who takes part in each conversation.

How is this different from opening five chat tabs?

Every model receives the identical prompt, so the comparison starts fair, and the answers arrive side by side instead of in five tabs you reconcile by hand. In Discussion mode the models also read each other, which no number of tabs will give you.

How does Discussion mode work?

The models answer first, then read the other answers and respond to the strongest objection to their own. A moderator runs the rounds and closes with a synthesis that quotes the participants verbatim rather than paraphrasing them.

Which model moderates?

Every plan uses GPT-5.6 Luna as the moderator, selected for citation accuracy in real-world tests, not for price. When possible, ChatRound chooses a moderator from a provider that has no other model in the discussion, so a model never evaluates its own answer. You can also assign the role to any model available through OpenRouter or a connected custom endpoint.
