Contradiction finder

Deep analysisGoes in: Chat

Sources rarely agree as much as a summary implies. This surfaces the disagreements a polite answer smooths over.

List every place where the sources disagree with each other — factual claims, numbers, recommendations or interpretations. For each disagreement: quote both sides verbatim, name the sources, and state whether it is a real contradiction or just a difference in scope or definitions.

How to use it

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

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

Build a topic index firstRun this before anything else on messy material — transcripts, mixed PDFs, scattered notes. The index becomes the map for every later question.
Explain one topic across all sourcesThe follow-up to the index. “Explain” keeps structure and nuance that “summarize” throws away; going topic-by-topic forces full coverage.
Structured synthesis with rulesThe heavyweight. A research-grade answer with explicit rules, so the model can't paper over gaps or drift outside the sources.
Assumption mapperFinds what the material takes for granted — the fastest way to spot where an argument is weakest.
