Is this AI summarizer free?

Yes, 100% free. No signup, no word limits, no subscription. The AI model runs in your browser.

How does it work without a server?

It uses Transformers.js to run a quantized BART summarization model directly in your browser via WebAssembly. No text is sent to any server.

What's the maximum text length?

The model handles up to about 1024 tokens (~700 words) per request. For longer documents, paste the most important sections.

Does the model download take long?

The quantized model is about 200MB and downloads on first use. After that, it's cached and loads in seconds.

How accurate are the summaries?

The model produces abstractive summaries — it rephrases key points rather than extracting sentences. Quality is comparable to online summarization APIs.

How AI Text Summarizer works

This tool uses Transformers.js to run a DistilBART summarization model entirely in your browser via WebAssembly. DistilBART is a distilled version of Facebook's BART model, trained specifically for abstractive summarization. Unlike extractive methods that just pick sentences, BART generates new text that captures the key points in fewer words. The model downloads once (~200MB) and is cached in your browser's storage. After that, summaries are generated locally without any internet connection. Your text never leaves your device.
