COMMON QUESTIONS

Before your first question

Models, costs, and how answers are compared.

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 up to 40 model turns a month, and Pro is $19 a month — or $14.99 a month billed annually — for up to 1,200 advanced turns and 8,000 basic. Platform-funded use also has a monthly ceiling; reach it and you can connect your own key to keep going, or pick up again on the 1st.

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?

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 can I compare answers from ChatGPT, Claude, and Gemini?

Ask once and compare their answers side by side in one place. An automatic summary highlights key takeaways and disagreements with quotes. You can then send targeted follow-ups.

Do I need to make the models discuss?

No. You get model answers and a summary first. If useful, choose follow-ups that let selected models respond to other answers. Additional model responses use turns.

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.
