Where facts go wrong on published pages

They were right when you wrote them

Most wrong facts were never wrong at publication. Prices changed, a study was superseded, a company was acquired. The page did not move; the world did.

Nobody re-reads the archive

Editors check new articles. The 300 old ones that still get traffic are read by visitors, raters and AI systems, not by anyone on the team.

One wrong number costs the whole page

Google's quality raters are told that factual inaccuracies lower their assessment of trust. Readers apply the same rule: the first stale figure they spot makes them doubt the rest.

How fact-checking works with CiteRanger

One URL in, a verified claim list out. Run it before publication, after a major update, or on a schedule.

1

Enter the page

Paste a URL, or import several via CSV or sitemap. CiteRanger fetches the published content, the same way a reader sees it.
2

Every claim is extracted and verified

The AI identifies each factual statement (statistics, prices, dates, company facts, product details, regulations) and checks it against current, authoritative sources across several providers. Claims that no source can confirm are flagged as unverifiable rather than guessed.
3

Review the verdicts

Each claim gets a status: confirmed, outdated, or unverifiable. Outdated claims show the current value and a link to the source that supports it. Fix the page, export the list, or set an alert so you hear about the next change.

What CiteRanger checks in every article

The scan extracts every factual claim from the page and verifies it against current sources. Six claim types cover most of what goes stale.

Statistics and numbers

Market sizes, growth rates, survey results, percentages

Prices and plans

Product prices, subscription tiers, fees, cost comparisons

Company facts

Employee counts, headquarters, leadership, acquisitions

Dates and timelines

Product launches, deadlines, historical events, schedules

Product details

Specifications, features, integrations, limitations

Legal and regulatory

Regulations, requirements, certifications, standards

Fact-checking that fits an editorial workflow

Claim-level results

Not a page score but a list of statements, each with a verdict, a corrected value where one exists and the source behind it.

Multi-provider verification

Claims are cross-checked across several AI providers and sources, which reduces single-model errors on numbers and dates.

Unverifiable is a result too

When no current source confirms a claim, CiteRanger says so instead of inventing a correction. Those are the claims to source or remove.

Alerts for facts that expire

Put time-sensitive pages on a schedule and get an email when a checked fact changes, so the correction happens before a reader notices.

Frequently asked questions

What is a fact-checking tool for content?

Software that takes a published page, extracts the factual claims in it and verifies each one against current sources. Unlike a plagiarism or grammar checker, it judges whether statements are still true. CiteRanger does this per claim and returns the corrected value with a source link.

Which kinds of facts does CiteRanger check?

Statistics and numbers, prices and plans, company facts, dates and timelines, product details and legal or regulatory statements. Opinions, predictions and general descriptions are not fact-checked because there is nothing to verify them against.

How accurate is AI fact-checking?

CiteRanger cross-checks claims across several providers and only marks a claim as outdated when a current source contradicts it; the source is shown so you can verify in one click. Claims without a confirming source are labelled unverifiable, not corrected. Treat the report as a verified lead list for an editor, not as an automatic rewrite.

Can I fact-check content before publishing?

CiteRanger scans published URLs. For drafts, publish to a staging or unlisted URL that is reachable from the web and scan that. Many teams scan right after publication and again on a schedule.

Does it replace an editor?

No. It replaces the part of the editor's job that nobody has time for: re-reading old pages and looking up every number. The decisions about what to change stay with people.

What does a scan cost?

One credit per page. The free plan includes 15 credits with every feature and no credit card. Paid plans start at 100 credits a month.
