Summary  
This chapter explains how to implement code that uses a language model to automatically summarize long documents by extracting main ideas, decisions, and required actions, and how to guide the summary based on specific goals.

General domain of usage  
Document analysis and knowledge management.


Long documents take time to read, especially when you only need the key points.
Gemini helps you extract the most important information in seconds.





## Situation

You receive a long document from a colleague.
It can be a report, internal policy, or meeting notes.
You do not need every detail. You **need to quickly understand**:

* What this document is about;
* What decisions were made;
* What actions are required.





Inside Google Docs, you open the document and use Gemini.




Summarize this document in a single paragraph, highlighting key decisions and next steps.

Prompt

Gemini generates a short version with the main ideas.





You can guide the result depending on your goal.



Provide a short summary in 5 bullet points.

Summarize this document for a quick update to a manager.


You receive a concise summary instead of having to read the entire document. The output highlights what is important, rather than every minor detail.
