A second opinion on your decisions, from a different AI company than the one you think with.
Setup guide: grillyour.ai
Tell the assistant you think with, "grill this": Claude, ChatGPT, Copilot, Gemini, Grok or Muse. It writes up your decision, and you check it. Then an outside judge, a model from a different company, argues the strongest case against it. It names the cheapest test that would settle each doubt, and gives a verdict. Before you decide, you write what you expect, how sure you are, and what would prove you wrong. You can look back later from a record you keep. Grill does not store it.
Verdict: shaky. The plan assumes customers stay at the new price, and nothing in it tests that. Falsifier: show the new price to one in ten new signups for two weeks, and compare how many start paying.
Claude Desktop and Claude Code enforce that in code. The copy-and-paste routes check it and warn you. Who to paste into is in the table below.
The extension reads GRILL_API_KEY. OPENROUTER_API_KEY works when that is unset.
mtangoz/grill.Want it in one step? Use Claude Desktop, above.
| You think with | Judge with |
|---|---|
| ChatGPT | Claude, Gemini or Grok |
| Copilot | Gemini, because Copilot can run OpenAI, Anthropic or xAI models |
| Gemini | Claude, ChatGPT or Grok |
| Grok or GrokBot | Claude, ChatGPT or Gemini |
| Muse | Claude, ChatGPT or Gemini |
It asks for your model router key. Grill reads GRILL_API_KEY first. OPENROUTER_API_KEY works when that is unset.
Grill is free. On your own key a grill is about a few cents. Copy and paste uses the assistants you already have.

Optional, in Claude, when you keep your own decision log: docs/WEEKLY-REVIEW.md.
