Get a free second opinion on any AI answer
Not sure a ChatGPT or Claude answer is right? Paste it below. In about 15–30 seconds you get an honest audit — the most important hallucination risks, unsupported claims, weak reasoning and missed caveats, each with a one-line reason, plus a clear verdict on whether it’s safe to rely on. No signup, nothing charged.

What the audit looks for
The six ways AI most often gets you into trouble — and the audit’s hard rule is to flag only the ones genuinely in your text, never to invent an issue to look thorough.
Invented or unverifiable facts, citations, cases, statistics, names or dates.
Assertions stated with no evidence or reasoning behind them.
Logical gaps and leaps the conclusion quietly leans on.
Conditions, exceptions and assumptions the answer glosses over.
Two parts of the work — or two numbers — that don’t reconcile.
A certain tone on something that is actually contested or context-dependent.
How it works
Drop in the ChatGPT or Claude answer you’re unsure about, a claim you’re about to rely on, or a draft you want checked.
In about 15–30 seconds you get the flags that matter most — each with a one-line why — and an honest verdict, including “nothing material found” when that is the truth.
Hand the same work to the full Multi-Agent Team — rival models debate it and a Final QA audit signs off the deliverable. Included with Plus.
One model’s pass, or four rival models and a sign-off?
This tool is a quick first pass. For work where being wrong is expensive, the full Decidi council runs it across GPT, Claude, Gemini and Grok, debates it, audits the verdict, and hands you a downloadable deliverable.
Questions
Is the AI second opinion really free?
Yes. Paste an answer, click “Audit it free”, and you get the audit in about 15–30 seconds. No account, no card, no credits. It is one of two free ways in — the other is Decidi’s chat, also free and account-free.
What does it check for?
It reads the work as a sceptical expert and flags the few things that matter most before you trust it: hallucination risk (invented or unverifiable facts, citations, numbers), unsupported claims, weak or leaping reasoning, missed caveats and conditions, internal contradictions, and overconfidence on things that are actually uncertain. It only raises real issues — it will never invent a flaw to look thorough, and it tells you plainly when the work looks solid.
Does it work on ChatGPT, Claude, Gemini and Grok answers?
It works on text from any source — a ChatGPT or Claude answer, a Gemini or Grok response, a Copilot code explanation, a claim from a colleague, or your own draft. If you can paste it, it can audit it.
What happens to the text I paste?
It’s sent to one model to produce the audit and returned to you. It isn’t saved to an account, added to any history, or shown to anyone else. This free tool is stateless — nothing you paste is stored.
How is this different from just asking another AI to check it?
Asking the same kind of model to “check this” often gets you the same blind spots and a polite “looks good”. This audit is built for one job — catching how AI actually fails — with a hard rule against fabricating issues. And when you need real confidence, the full Decidi council puts four rival models against the work and audits the result.
What’s the difference between this and the full Decidi council?
This is one model’s quick pass — fast, free, and enough to catch the obvious risks. The full council runs your work across four independent frontier models (GPT, Claude, Gemini, Grok) that debate it, an impartial moderator writes a verdict, an always-on Final QA audits that verdict, and you get a downloadable, sign-off-ready deliverable. Chat is free; full Multi-Agent runs are included with Plus at $19 a month.
