🔁 A second opinion is the point

Best AI for a Second Opinion
Get Three, Not One

A second opinion is only useful if it's truly independent. CouncilMind runs your question through four frontier models in parallel—GPT-5, Claude Opus 4.6, Gemini 2.5 Pro, DeepSeek V4 Pro—and surfaces exactly where they disagree.

🎯 Claude Opus 4.6

The standard answer is X. Most sources agree.

🧠 GPT-5.5

X is right in the typical case, but the question implies the edge case—where Y is correct.

🔬 DeepSeek V4

Synthesis: X is the right default; Y kicks in when the user's premise is the edge case implied here.

A second opinion that's actually independent

Why You Need More Than One Model's Opinion

The same training data produces correlated mistakes

Independent Reasoning

Different model families, different training pipelines, different biases. When they agree, the answer is robust.

Disagreement Highlighted

The most useful output isn't the consensus—it's the dissent. That's where the verification work goes.

Skeptic Persona Available

Run a skeptic pass to find the strongest counter-argument to any answer.
