ChatGPT can make mistakes. Check important info.
Fine. Check it with what?
Every frontier AI ships the same admission in grey 12-point type: this can be wrong, go verify it. Not one of them hands you the means to. You are told to check — by the only thing you had to check it with. Decidi is the check. Rival models from rival labs audit the answer and tell you exactly which parts won’t survive contact with reality.
No signup, nothing charged — paste an answer and see.
Six labs. One confession.
Quoted verbatim from the products themselves and their makers’ own documentation. The most honest sentence each of them writes is the one they set in the smallest type.
“ChatGPT can make mistakes. Check important info.”
“Gemini can make mistakes, so double-check it”
“Claude can make mistakes. Please double-check responses.”
“Grok can make mistakes.”
“AI-generated content may be incorrect”
“Messages are generated by AI and may be inaccurate or inappropriate”
“Copilot is for entertainment purposes only. It can make mistakes, and it may not work as intended. Don’t rely on Copilot for important advice. Use Copilot at your own risk.”
Microsoft’s Copilot terms of use, last updated 24 October 2025. After it was reported in April 2026, Microsoft told PCMag this was “legacy language” that no longer reflected how the product is used, and said it would be changed. Source
“Check important info” is a task, handed to the person least able to do it.
If you could tell which sentence was invented, you wouldn’t have needed the AI. And the obvious move — asking the model “are you sure?” — is the one that doesn’t work: its mistakes and its confidence come from the same place, so it re-states the error with more conviction. Checking only means something when the checker is independent.
Every major lab prints the same warning under its own answers.
The verification is assigned to you, with no tool and no method.
Rival models from rival labs audit the answer and name what to fix.
Paste the answer you were told to check
Any AI answer, claim or draft. In about 15–30 seconds you get the hallucination risks, unsupported claims, weak reasoning and missed caveats — each with a one-line reason — and an honest verdict on whether it’s safe to rely on. Free, no signup, nothing stored.
Free · no signup · nothing charged. One model’s quick pass.
One model’s pass, or four rival models and a sign-off?
The audit above is a fast first pass. When the answer is going into a contract, a diagnosis, a filing, a board pack or production code, the full council runs it across GPT, Claude, Gemini and Grok, makes them argue, audits the verdict with a separate Final QA pass, and hands you a deliverable you can put your name on.
Questions
What does “ChatGPT can make mistakes. Check important info.” actually mean?
It is OpenAI telling you, under every conversation, that ChatGPT’s answers are generated probabilistically and can be confidently wrong — so anything that matters must be verified before you rely on it. It is not boilerplate. It is the single most important sentence on the screen, and it is the one nobody acts on, because OpenAI does not give you a way to act on it.
Do the other AI assistants say the same thing?
Almost word for word. Google prints “Gemini can make mistakes, so double-check it”. Anthropic prints “Claude can make mistakes. Please double-check responses.” xAI prints “Grok can make mistakes.” Microsoft shows “AI-generated content may be incorrect”. Meta shows “Messages are generated by AI and may be inaccurate or inappropriate”. Every major lab admits the same limitation, in the same small grey type, and leaves the checking to you.
How do I check important info from an AI?
Not by asking the same model “are you sure?” — it has the same training data, the same gaps and a strong pull to agree with you, so it will usually reassure you. Real checking means an independent opinion: put the answer in front of models from different labs, have them look for the invented fact, the unsupported claim, the missed condition, then take the points they disagree on as your verify-this list. That is exactly what Decidi runs.
Why can’t an AI just check itself?
A model’s errors and its confidence come from the same place. When a model hallucinates a case, a statistic or an API that does not exist, it has no internal signal that anything went wrong — so asking it to review its own answer tends to reproduce the error with an extra layer of reassurance on top. Independence is the whole mechanism: a different model, trained differently, is the thing most likely to notice.
Is checking an answer on Decidi free?
Yes. Paste any AI answer into the audit on this page and you get the flags that matter — hallucination risk, unsupported claims, weak reasoning, missed caveats — in about 15–30 seconds. No account, no card. When the stakes justify it, one click escalates the same work to the full council: four rival frontier models debate it and a Final QA audit signs off a deliverable.
