Get a second opinion before you decide.
The AI you chat with tends to agree with you. Grill asks a different AI to find the weak spots in your plan, then gives you one quick way to check each one. Before you commit, not after.

How it works
It’s called Grill because a good plan can take a few tough questions.
- Tell your AI what you’re deciding, and how sure you are.
- It writes a short summary. You check it before anything is shared.
- A second AI, from a different company, looks for the weak spots and suggests a quick way to check each one.
- You get a simple result: solid, solid if…, shaky, or doesn’t hold up.
Works with the AI you already use
The second opinion always comes from a different company than the AI you normally use. That’s the point: it won’t share the same blind spots.

Your privacy
Grill has no accounts and keeps nothing. Only the short summary you approve is shared, never your notes or files. If you copy and paste, it goes to the AI you paste it into. With the one-click version, it goes only to AI services that don’t store it, plus a quality check that’s on by default (Grill tells you each time, and you can turn it off). Email addresses, phone numbers and card numbers are hidden before anything is sent. And Grill gets better by practicing on made-up examples, never on your decisions. The details are in the privacy notes.
