It uses a client-side extractive text-mining script. By filtering out structural stop words and computing individual sentence weights relative to localized token distributions, it naturally surfaces the most informative talking points right inside your device runtime environment.

Yes, completely. There are zero background network payloads, external API targets, or tracking checkpoints. The text never travels across the internet, making it ideal for processing enterprise documents, academic notes, or private logs.

The primary extraction stop-word directory is optimized for English grammatical styling. While foreign language inputs will still process based on core term-density frequencies, language-specific syntax structures may yield varying weights.

No. Because all computing occurs natively in your browser thread, there is no arbitrary cloud threshold capping your character limits. However, exceptionally long textbooks might see a slight performance variance depending on your device processing speed.

The text cache resides temporarily in your volatile browser memory. Clicking “Clear” or shutting down the active tab completely destroys the local variables, leaving behind zero forensic footprint or cookies.

No, this is an extractive summary tool, not a generative writer. It highlights the actual, unaltered sentences that carry the heaviest contextual information load within your document, ensuring you always review verified, raw source data without creative hallucinations.
