How does the AI text summarizer work?

The tool uses DistilBART CNN (a distilled version of Facebook's BART model) running in your browser via Transformers.js and WebAssembly. It reads your text and generates an abstractive summary — not just extracted sentences, but a newly written condensed version.

Why does it take a moment on first use?

The AI model (~100MB) is downloaded from Hugging Face CDN on your first use and cached in your browser. Subsequent summarizations are much faster.

Is my text sent to a server?

No. All processing happens 100% in your browser using WebAssembly. Your text never leaves your device.

How long can the input text be?

The model works best with texts up to about 500—700 words. For longer documents, the tool automatically uses the first 768 words. For best results with very long articles, you can split them into sections.

What is the difference between Short, Medium, and Detailed?

These settings control the target length of the generated summary. Short produces 1—2 sentences, Medium produces 3—5 sentences, and Detailed produces a full paragraph. The AI model itself determines the exact output based on the input.

What is the difference between extractive and abstractive summarization?

Extractive summarization selects the most important sentences directly from the original text. Abstractive summarization generates new sentences that paraphrase the key points. Our tool uses a combination of both.
