How to Summarize Text Online with AI
- Paste your text into the input area — articles, emails, reports, or any plain text up to 15,000 characters.
- Select a summary length: Short for a quick overview, Medium for the key points, or Long for a detailed condensed version.
- Click Summarize. On first use, a one-time model download (~343 MB) is required — your browser saves it locally for instant reuse.
- The summary appears in the output area below. For texts over ~700 words the tool splits the input into chunks automatically and produces a final combined summary.
- Click Copy to copy to your clipboard, or Download .txt to save the summary as a file.
When to Use Each Summary Length
| Length | Output | Best for |
|---|---|---|
| Short | 3–4 sentences | Quick headlines, social media captions, TL;DR snippets |
| Medium | 5–7 sentences | Email summaries, meeting notes, blog post outlines |
| Long | 8–10 sentences | Research papers, long reports, detailed article digests |

Frequently Asked Questions
Is my text uploaded to your servers?
No. Your text never leaves your device. The entire process runs inside your browser — nothing is sent to or stored on any server.
Is this free to use?
Yes, completely free. No account required, no usage limits, and no hidden charges.
Why is the first summarization slow?
The first time you use the tool, your browser downloads the AI model (~343 MB — encoder and decoder ONNX files). After that one-time download, the model loads instantly from local storage and the tool works offline too.
What is the maximum text length?
Up to 15,000 characters. For texts longer than ~700 words the tool automatically splits the input into chunks, summarizes each one, then merges them into a final summary.
Does it work offline?
Yes. After the model is downloaded on your first use, it is saved to your browser's local storage. You can then summarize text with no internet connection.
Which AI model does this use?
DistilBART (distilbart-cnn-12-6) by Facebook/Hugging Face — a distilled version of BART trained on CNN/DailyMail news. It runs as quantized ONNX encoder + decoder models via Transformers.js in your browser using WebGPU or Web Workers. The one-time download is ~343 MB.
