## The prompt

```
Find the non-obvious connections between sources in this notebook that appear unrelated on the surface.

For each connection:
1. Name the two (or three) sources being bridged.
2. State the shared underlying idea, mechanism, or pattern in one sentence.
3. Quote the key passage from each source that demonstrates the link.
4. Explain why this connection isn't obvious — what surface-level differences hide it.
5. Describe one new insight or angle that only becomes visible once both sources are read together.

Aim for 5 strong cross-source connections. Prefer surprising bridges over safe ones. Skip anything where the link is already explicit in either source.
```

## How to use it

1. Open your notebook at notebooklm.google.com.
2. Replace the [bracketed] parts with your specifics.
3. Paste the prompt into the chat box and send it.

Square brackets mark the parts you replace with your own topic or question.
