An AI second opinion that actually disagrees with you when you are wrong
A second opinion is only useful if it is genuinely independent. Ask the same chatbot you used to make a plan and it will mostly agree with itself — and with you. What you need is a fresh, sceptical look from people (and models) who have no stake in your original conclusion.
Decidi gives you a structured second opinion from four rival models and a panel of expert personas who did not write your plan. They review your reasoning, attack the weak points, and tell you plainly whether the original call holds up — and what would change it.
- Independent review from models with no stake in your first answer
- Sycophancy filtered out by pitting models against each other
- Hidden assumptions named and tested, not rubber-stamped
- A clear verdict: does the original decision hold, and why
- Specific, actionable changes rather than vague reassurance
- Attach the original plan, contract or analysis for grounded review

A verdict on your existing plan: confirmed, confirmed-with-changes, or reconsider — with the specific reasons and the fixes.
Common questions
Why not just ask ChatGPT for a second opinion?
Because it is not a second opinion if it comes from the same source as the first, especially when the model tends to agree with how you framed things. Decidi brings four independent models and personas who challenge the original conclusion rather than echo it.
Will it tell me I am wrong?
Yes, when you are. The whole design pushes against agreement bias: a dissenting view is always recorded, and the moderator states plainly whether your original decision survives scrutiny.
Can I get a second opinion on a document or contract?
Yes. Attach the document and the council reviews it directly — flagging risky clauses, weak arguments or missing considerations — then gives you a grounded second opinion on whether to proceed.
