A GUIDE TO CHOOSING
Start with Perplexity if you need to find information on the Web. Consider Gemini Notebook, formerly NotebookLM, if you have documents to compare and question. These uses can follow one another: research, source selection, then synthesis.
A SELECTION WITH THE CHOICES EXPLAINED
The options to compare.
Our recommendations are editorial: choose for your use case, then test with the same brief.
Perplexity
Explore a topic and find the sources
- Choose it for
- Start a Web search and identify the pages to consult for a deeper understanding or to verify information.
- The trade-off to know
- A citation alone does not prove that a claim is correct. Open the page and check the date and the cited passage.
My first test
Ask a precise question, specify the time period and request official sources. Then open the selected sources.
Check: On personal plans, check the AI Data Retention setting before processing sensitive information.
Gemini Notebook (formerly NotebookLM)
Get answers from your chosen sources
- Choose it for
- Understand a collection of documents, connect ideas and prepare a synthesis based on selected sources.
- The trade-off to know
- The result depends on the sources added. Citations may be less detailed for a short document; capacity and usage remain limited according to your plan.
My first test
Create a notebook with three reliable sources on one topic. Ask for a synthesis that distinguishes points of agreement, differences and missing information.
Check: Only add sources you have the right to use. On a personal account, feedback sent to Google may include your sources and answers.
No tools match this search.
