AI Summarizer
Paste any long text and get a concise summary instantly. Uses extractive summarization — no data is sent to any server.
How It Works
This tool uses extractive summarization: it splits your text into sentences, scores each sentence based on word frequency and position, and picks the top-scoring sentences. No AI model or external API is used — it all runs in JavaScript in your browser.
Frequently Asked Questions
Is my text sent to a server?
No. All summarization happens in your browser using JavaScript. Nothing is uploaded.
How does the summarization algorithm work?
It uses TF-based extractive summarization. Sentences are scored by the frequency of their words and their position in the text, then the highest-scoring sentences are selected.
