Use it to check a draft, a pitch or an article before it goes out. Paste the prompt below into the NotebookLM (Gemini Notebook) chat and replace the parts in square brackets. It tells NotebookLM to answer only from your sources, cite them and flag what they do not cover.

## Quick facts

| Item | Detail |
| --- | --- |
| Works in | NotebookLM / Gemini Notebook chat, and the customise box of Studio items |
| Sources needed | Your draft as one source and the supporting documents as the others. |
| Cost | Free to copy. Saving it in the extension is free for up to 10 plain prompts. |

## The prompt

```text
Audit the draft titled [DRAFT SOURCE NAME] against the other sources.
List every factual claim in the draft. For each one give:
Claim | Supporting passage and source | Verdict
Use these verdicts: Supported, Partly supported, Not found in sources, Contradicted.
Quote the supporting passage in 25 words or fewer. Do not judge style.

Use only the sources in this notebook. Cite the source for every claim. If the sources do not cover something, say "not covered in the sources" instead of filling the gap.
```

## How to use it

1. Open the notebook and tick only the sources this question is about.
2. Paste the prompt into the chat and replace every part in [SQUARE BRACKETS].
3. Open two or three citations in the answer to confirm they say what the answer claims.
4. Save the answer as a note, then keep it: [Export the audit to PDF](https://nlmexporter.com/guides/export/chat-history-to-pdf).

## Adapt it

- Limit the audit to numbers and dates for a fast first pass.
- Ask for a rewritten version of each claim marked Partly supported.

> NotebookLM can misread or over-generalise a source. A prompt reduces that; it does not remove it. Check cited passages before you rely on an answer.

## Frequently asked questions

### What should be in the notebook before I use the audit a claim against the evidence prompt?

Your draft as one source and the supporting documents as the others.

### How do I save this prompt in NotebookLM?

NotebookLM has no prompt library of its own. With NotebookLM Ultra Exporter you can save it to My prompts and insert it in the chat box by typing /. Free saves 10 plain prompts; variable templates, folders and backup need Pro.

### Why does the prompt ask NotebookLM to say what is not covered?

Because a grounded tool is most useful when it shows the edges of your sources. An explicit instruction to flag gaps reduces confident answers that the sources do not support.
