The right model, every time.

arbiter is one text box. It reads what you ask and routes it to whichever AI model is best suited — Claude, GPT, Gemini, Perplexity and more. No picker, no decision. Most questions go to a fully capable, efficient model; when an answer falls short, one button re-runs it on something stronger.

No account needed to start. arbiter is software, not a person.
