AI-assisted research, source-checked and reviewed by a human editor. How we work
To fact check AI answers, start by separating verifiable statements from advice and then follow each important claim back to reliable evidence. A practical workflow to verify AI-generated facts, citations, calculations, and claims before using them in professional work. This guide provides decision points and checks you can apply without assuming any AI output is automatically correct.
Why confident answers can still be wrong
A language model can produce clear, plausible sentences that are false or unsupported. NIST’s Generative AI Profile discusses these confabulations as a risk of generative systems. They can include invented source details, incorrect dates, merged product features, or a real fact applied to the wrong context. Confidence in the writing style is not evidence. A better habit is to classify which claims matter and verify them before reuse. Creative suggestions may need judgment; factual claims need sources.
Step one: extract checkable claims
Take a generated answer and highlight every statement that could be true or false: numbers, dates, legal requirements, product features, quotations, and comparisons. Separate recommendations from claims. For an article about an AI tool, ‘the interface is easy to use’ is an opinion, while ‘the free plan supports a particular export format’ is a checkable product statement. Make a quick claim log with a source column and a verification status column. Start with claims that could cause harm or alter a purchase.
Step two: find primary sources
Prefer official documentation for product capabilities, a published paper for research findings, or the issuing agency for rules. Check effective dates and whether a source describes the same country, plan, model, and software version. Search snippets alone can omit caveats. Read the actual page. If a vendor claims superior performance, label it as a vendor claim unless independent evidence supports the comparison. Use a credible secondary source to add context, not to replace an accessible original.
Step three: verify citations and quotes
A URL can be real while the attributed claim is not. Open each citation and search for the supporting passage. Check whether the article quotes the document accurately and preserves qualifications. Avoid copying more of a source than you need; paraphrase clearly and link to it. If a quote cannot be found, remove or correct it. If two authoritative sources disagree, state the disagreement and date both rather than hiding it.
Step four: reproduce arithmetic and examples
For calculations, recompute the result using a calculator or spreadsheet, inspect units, and confirm whether percentages use the correct denominator. For coding claims, run small tests in a safe environment and disclose what was actually tested. For product tutorials, follow the steps on the current interface before presenting them as verified. Do not say ‘tested’ if you only read documentation. A useful fact-check report distinguishes confirmed, plausible but unverified, and incorrect claims.
Step five: record uncertainty
Some questions cannot be settled with available evidence. Instead of filling the gap with a likely-sounding answer, use language such as ‘the vendor documentation does not specify’ or ‘I could not verify this feature for this plan.’ Give the reader a method to confirm it. Recheck fast-changing material near publication and attach a review date. NIST’s Generative AI Profile is a useful risk reference.
A five-minute editorial checklist
Before sharing an AI-assisted draft: verify every consequential number; open every external citation; check titles and dates; distinguish tests from demonstrations; run calculations independently; remove unsupported absolutes; and state unresolved uncertainties. This workflow will not eliminate every error, but it makes review explicit and repeatable.
Maintain a small fact-check log
An editorial log can be as simple as five columns: claim, source URL or document, source date, verification result, and reviewer note. Mark a claim confirmed only when the referenced material supports its wording and scope. If a document says a feature is available ‘for selected customers,’ an unqualified sentence saying it is available to everyone should fail review. When a feature changes, the log tells you exactly which article needs an update.
Schedule follow-up checks based on volatility. An explanation of OCR concepts may remain useful for a long time; an AI product price or plan limit might change next week. Avoid changing an accurate article simply to refresh its date. Update only when the new review uncovers material changes, and make those changes visible to readers where they matter.
FAQ
Can I trust an AI answer with citations? Only after checking that they support the claim. What should I verify first? High-impact claims and time-sensitive details. Does asking another chatbot count as fact-checking? Not by itself; both may repeat the same error. Should I publish an unresolved claim? Usually remove it or label the uncertainty clearly.

A fact-check AI answers example: a product comparison
Suppose an AI-generated comparison says that Tool A exports files on its free plan, Tool B processes data only in a particular region, and Tool C has unlimited usage. These are three separate claims with different evidence requirements. For Tool A, consult the current plan documentation. For Tool B, read the provider’s regional processing and contractual material rather than its marketing headline. For Tool C, check rate limits and fair-use conditions. If any claim cannot be verified, remove the comparison cell or clearly label it unconfirmed.
A better comparison has a ‘source checked’ date and a link next to each time-sensitive assertion. Readers can then distinguish a documented feature from a subjective recommendation.
Use a claim-evidence table
| Claim | Best evidence | What to check |
|---|---|---|
| Price or plan feature | Vendor plan documentation | Region, billing cycle, limits |
| Research result | Original study or dataset | Method, sample, uncertainty |
| Legal obligation | Relevant authority or qualified expert | Jurisdiction and effective date |
| Product performance | Reproducible methodology | Version, test setup, comparison |
This structure stops a long paragraph from hiding a weak source among strong ones. It also makes later updates easier: the editor can revisit the volatile rows first.
A verification prompt that helps but does not replace research
Try: ‘Turn this draft into a list of factual claims. For each claim, identify what source would prove or disprove it. Highlight time-sensitive details and claims that lack direct evidence. Do not invent citations.’ The assistant may still miss claims, so read the draft yourself. For a numerical statement, ask for the formula and reproduce it independently. For a quote, inspect the exact wording in the source.
Be cautious of confirmation bias. Searching only for the exact sentence an AI generated may find copies of the same unsupported claim. Broaden the search to primary evidence and credible disagreement.
Prioritize checks by possible harm
A wrong description of a decorative icon is inconvenient. A wrong medication dose, employment rule, security instruction, or wire-transfer detail can be harmful. Spend review effort according to the consequences of error. For high-stakes topics, a general-purpose chatbot must not be the final authority. Have a qualified professional review the relevant facts and limitations.
NIST’s Generative AI Profile documents risks including confabulation and provides a broader context for responsible AI use.
How to fact check AI answers before publication
To fact check AI answers reliably, extract the claims, prioritize important ones, consult current primary evidence, reproduce calculations, inspect quotations, and document uncertainty. Keep a simple revision log so a second editor can see what changed. A well-sourced correction is more valuable to readers than preserving a fluent but unsupported paragraph.
