## Answers you can check, down to the line

Every line Quelvio quotes is the document's own words, with its source, its date and whether it still holds. Open it and check.

An answer you can't check is a guess you have to trust. Quelvio answers from your documents and shows its work: the lines that answer, highlighted, each with where it came from, its date, and whether it is current.

## Quoted means quoted

When Quelvio shows a line as a document's words, they are the document's words, letter for letter. If a person corrected the line, you see who corrected it, when, and what the document said before.

**Sample** · An answer, with its source line

```text

Travel and expenses policy · Meals · 1 March 2026 (stated) · in force · official · verified by Dana Weiss, 4 March 2026
```

## Your assistant writes the reply

When an agent, or your own assistant in Claude, ChatGPT or Microsoft Copilot, answers you, it words the reply from the lines Quelvio gave it. Quelvio hands over the lines with their sources, so there is always something to check the reply against.

## Open it

Open any line to read it in its document, and to see whether it still stands.
