How does probeo find factual errors on a page?

A page can be wrong in ways nothing flags: a fee that has changed, a deadline that applies in one state stated as a rule for all of them, a requirement the title promises and the page never gives. Probeo reads each page’s claims and records the ones that look wrong, with an accuracy level for the page as a whole.

What probeo checks

• Accuracy: a level for the page’s main content, from very low to very high, or unable to assess. It comes with the evidence for it.
• Claims: up to three per page. Each records the claim as the page states it, what is wrong with it, and one of four severities: error, outdated, misleading or unverified.

On pages about money, legal requirements, health or safety, some findings hold accuracy at low by themselves:

• a requirement specific to one jurisdiction, presented as a universal rule
• a page whose title or introduction says it documents fees, timelines or requirements, and doesn’t give them
• information that is explicitly dated or plainly stale, on a topic where the requirements change often
• a claim that is demonstrably wrong, or that contradicts well-established expert consensus

How probeo checks it

Accuracy is part of probeo’s page quality reading. A language model reads the page and judges its claims against what is well established.

It doesn’t look anything up. It has no search and no access to outside sources, and it is told to use only the page as evidence. Probeo checks that the answer has the expected shape, not that each judgment is right.

What this does not cover

There is no live check against current official sources. Where the model can’t judge, a claim can be marked unverified and the page’s accuracy recorded as unable to assess.

Three claims per page is a sample, not an audit. Probeo records the claims; it doesn’t change the page.

Common questions

Does a page with no errors listed have none?

No. It means none were found in this reading. A specific fee, rate or deadline is worth checking against its official source whatever the reading says.

What does unverified mean?

It marks a claim the reading couldn’t confirm. It may be right; check it against its source.

Why only three claims?

The reading is kept compact so the whole page-quality report fits in one response, and the model is told to list at most three.
