Long Text → Short Summary Guide | Rune | Rune Blog

Turning a 5,000-word article into a 100-word summary is an art. AI makes it instant, but understanding the process helps you get better results. Here's your complete guide to long text → short summary conversion.

Understanding Compression Ratios

Original Length	Summary Length	Compression Ratio
500 words	50 words	10:1
1,000 words	100 words	10:1
2,500 words	150 words	~17:1
5,000 words	200 words	25:1

Higher compression = more condensed, less detail.

Choosing the Right Summary Length

Short (2-3 sentences)

Use for: Quick relevance assessment, social media sharing, email previews.
Compression: Maximum (~25:1).
Detail level: Core message only.

Medium (1 paragraph)

Use for: Meeting notes, literature reviews, general understanding.
Compression: Balanced (~15:1).
Detail level: Main points covered.

Detailed (2-3 paragraphs)

Use for: Comprehensive review, study materials, documentation.
Compression: Moderate (~10:1).
Detail level: Thorough coverage.

Step-by-Step Guide

Step 1: Prepare Your Text

Ensure the text is well-structured.
For very long texts (>15,000 characters), divide into sections.

Step 2: Choose Settings

Select appropriate length based on your needs.
Choose tone (formal, academic, creative, friendly).
Enable Key Points if you want bulleted takeaways.
Use Focus Mode for targeted summarization.

Step 3: Generate and Review

Review the output.
If needed, regenerate with different settings.

Step 4: Use Your Summary

Copy to clipboard.
Download as .txt file.
Integrate into your workflow.

Optimizing Results

Well-Structured > Poorly-Structured

AI performs better on text with clear paragraphs, headings, and logical flow.

Focus Mode for Specific Needs

Don't summarize everything—summarize what matters to you:

"What are the main recommendations?"
"Summarize the methodology."
"What are the pros and cons?"

Use Key Points for Action Items

Enable Key Points when you need discrete, actionable information rather than flowing prose.

Common Use Cases

Scenario	Recommended Settings
Quick article skim	Short length, no key points
Study material	Medium length, key points on
Business report	Detailed length, formal tone
Research literature	Medium length, academic tone, key points on
Social sharing	Short length, friendly tone

Conclusion

Long texts don't have to stay long. With Rune's AI Summarizer, you control the compression level, tone, and focus—transforming any content into exactly the summary you need.
