Prompt Tips for Using AI to Generate Summaries of Text

Crafting the right prompts can significantly improve the quality of AI-generated summaries. By following these tips, you can ensure that your summaries are accurate, relevant, and tailored to your needs.

Here are a few things we recommend to do when writing prompts for generating summaries with AI:

Be Clear and Specific

Clearly state what you want the tool to summarize and the level of detail you need. Ambiguous prompts can lead to incomplete or irrelevant summaries.

For example, specifying “summarize this article into three bullet points” provides the AI with clear guidance on the expected output.

Provide Context

Include additional details about the text or the purpose of the summary. Letting the AI know whether the summary is for a report, presentation, or quick review can improve the results.

Context helps the tool focus on the most relevant points based on your intended use.

Include Keywords

Incorporate important keywords or phrases related to the text to guide the AI’s focus. Keywords help the tool identify the main topics or themes of the text.

For example, asking the AI to "summarize this article about renewable energy, focusing on solar power advancements" can refine the output.

Specify the Format

Let the AI know how you want the summary presented, such as bullet points, a paragraph, or numbered steps. Specifying the format helps ensure the summary is immediately usable without additional reformatting.

For instance, asking for "a 5-sentence paragraph summary" can produce a concise, cohesive output.

Request a Focus Area

If the text covers multiple topics, tell the AI to prioritize a specific area of interest.

For example, in a long article about technology trends, you can prompt, “Focus the summary on advancements in artificial intelligence.” This ensures the output aligns closely with your needs.
