Frequently asked questions
Is my text sent to a server or an AI model?
No. The summary is produced entirely in your browser using a frequency-based extractive algorithm. Nothing is uploaded, so even confidential documents stay private.
How does the summarizer choose sentences?
It scores each sentence by how often its meaningful words appear across the whole text, favors information-dense sentences, then returns the top-scoring ones in their original order. It extracts existing sentences rather than rewriting them.
What length should I pick?
The slider sets the share of sentences to keep. 20–30% works well for articles; raise it for dense technical text where most sentences carry weight, lower it for a quick gist.
