Cosmic Trolley

A runaway trolley. Two fates. One verdict.

Name any two things: a person, a snack, an idea. An AI arbiter rules which one the trolley spares and explains why. Ask again and the ruling stands.

Shared quota

The shared arbiter runs on a community budget. Add a key from Gemini, Groq, OpenRouter, OpenAI, Anthropic, or DeepSeek and verdicts run on your personal quota instead.

    Architecture & Key Privacy

    • Stored in your browser only. Your key is saved locally in this device's localStorage. It is never written to our database, and clearing it here removes it immediately.
    • Encrypted in-flight proxy. To bypass browser CORS blocks and apply standard dilemma formatting, your key travels over an encrypted HTTPS connection to this site's Cloudflare serverless function for that single outbound request. It is held in ephemeral memory only and is never stored, tracked, or logged.
    • Stateless verdicts. We do not store queries or rulings in a database. Cross-device consistency is achieved via deterministic mathematical seeds, meaning identical inputs produce the same ruling without tracking what you type.

    Before you pull the lever

    Cosmic Trolley is an absurdist satirical engine for comparing hypothetical concepts, people, and everyday objects.

    Every verdict is fictional and generated by an AI model. None of it constitutes moral, philosophical, or real-world advice, and we accept zero liability for existential crises, broken friendships, or cold pizza debates.

    Data & API handling. The entities you compare are processed statelessly without saving queries to a database. If you configure a custom API key, it passes over an encrypted HTTPS connection through our serverless function directly to your chosen provider for that single query; it is never logged, tracked, or stored.
