What is AI Text Summarization?
Text summarization uses artificial intelligence to condense long documents into shorter, coherent summaries. This tool uses DistilBART, a state-of-the-art encoder-decoder model trained to understand text structure and extract the most important information while maintaining readability and coherence.
Text summarization is essential for quickly understanding long articles, research papers, news stories, and documents. It helps readers grasp key points without reading entire texts, saving time and improving information consumption efficiency.

Common Questions
How accurate is AI text summarization?
The DistilBART model produces highly coherent summaries that capture main ideas well. It works best on well-structured text like news articles, essays, and reports. Results may vary with technical jargon, very short texts, or poorly formatted content.
What is the ideal text length for summarization?
Best results come from texts between 50-500 words. Very short texts (under 50 words) may not benefit from summarization. Very long texts may need to be processed in sections for optimal results.
Is my text data uploaded to a server?
No. The entire AI model runs in your browser using Transformers.js and WebAssembly. Your text is processed locally on your device and never transmitted to any server. This ensures complete privacy for sensitive content.
Why is there a large download on first use?
The first time you use the tool, it downloads the DistilBART model (~300MB) to your browser cache. This one-time download enables all future summarization to happen instantly without any server communication. The model stays cached for future use.
What does the compression ratio mean?
The compression ratio shows how much shorter the summary is compared to the original. For example, "75% shorter" means the summary is only 25% the length of the original text, condensing 4 pages into 1 page equivalent.
Can I control the summary length?
The AI automatically generates summaries of appropriate length based on input. Longer inputs typically produce longer summaries. The model targets 30-150 words for most summaries to balance brevity with completeness.
