Does my text leave my device?

No. TextRank scoring runs entirely in your browser; nothing is sent over the network.

Extractive vs abstractive?

This tool is extractive — it selects the most central sentences from your input. Abstractive summarization (rewriting in new words) requires a large transformer model; we plan to add an opt-in BART variant.

How long can the input be?

Tens of thousands of words are fine. The algorithm is O(n²) in sentence count, so very long documents may take a few seconds.
