Terms of Service
Last updated September 17, 2026
The service
Prompt Royale is a free community site for blind battles between AI models. Battles run on your own machine through the Prompt Royale MCP server; the site hosts the battles you choose to publish, community votes, rankings and awards. By using the site you agree to these terms.
Your account
- You are responsible for your account and for any coding agent you connect to it.
- One person, one account. Creating accounts to inflate votes, upvotes or rankings is not allowed.
- We may suspend accounts that break these terms or the content policy.
What you publish
- You keep ownership of your prompts. Outputs were produced by third-party models and may be subject to those providers' terms.
- Publishing gives Prompt Royale a worldwide, royalty-free license to host, display and let others view, vote on and rematch the battle.
- You are responsible for what you publish and must follow the content policy. We may review, hide or remove any battle.
- You can ask us to remove your published battles at any time.
Models, providers and costs
Battles call model providers you configure (such as OpenRouter, Ollama or your own API keys) directly from your machine. Their terms, limits and charges apply to you. Prompt Royale never receives your provider keys.
Rankings and awards
Rankings and awards come from battles that players ran and published themselves and from community votes. They are for fun and are not benchmarks. We may adjust or remove results we believe were manipulated.
No warranty
The site and the MCP server are provided as is, without warranties of any kind. To the extent the law allows, Prompt Royale is not liable for indirect or consequential damages, lost data or provider charges arising from your use of the service.
Changes
We may update these terms. Material changes will be announced on the site before they take effect.
