On an ordinary web page, DeepVerify reads the text, pulls out the statements that can actually be checked, and verifies each one. You can point it at the whole page or at a passage you select.

Checking a whole page

1

Open the side panel

Click the DeepVerify icon in the toolbar, or press Alt + F.
2

Press Check this page

A preview card shows which page is about to be checked, so you can confirm you are on the right one.

Watch claims arrive

Claims appear one at a time as they are found, each with its verdict. You do not have to wait for the whole page to finish before reading the first result.

Checking selected text

When you only care about one passage, select it instead of scanning the whole page. Three ways to start, all equivalent:
  • Press Alt + D
  • Right-click and choose DeepVerify with Factagora
  • Click the button that appears next to your selection
Selecting text is not a different kind of check — it is a page scan with the range narrowed by you. A selected paragraph is split into individual claims and each is checked separately, exactly as in a full scan.

Results accumulate

Selections merge into the same session as the page they came from. Scan a page and then select part of it, or select first and scan afterwards — either way the results add up instead of replacing each other, and History keeps one entry for the page rather than one per attempt.

Highlights on the page

Checked claims are marked in the article itself, not only in the side panel. Hover a highlight to see the verdict, confidence score, and the sources behind it without opening the panel. Open in panel jumps to the full card.

Running without being asked

Auto-detect Claims scans pages as you open them and highlights what it finds, so you can see what is worth verifying before you start reading. It is off by default — see Automation.
