Frequently asked questions
Is this text summarizer free?
Yes. It's 100% free — no registration, no daily limits, no hidden subscriptions.
How does the TF-IDF algorithm help?
TF-IDF spots words that are unique and relevant to your text, not just common ones. That keeps the summary focused on the real substance of your content.
Is my content safe and private?
Yes. All processing runs locally in your browser. Your text is never uploaded to a server or stored anywhere.
Can I paraphrase the summary afterward?
Yes. Run the summary through the Paraphrasing Tool to create fresh bullet points for presentations or social media.
Can I generate more content from a summary?
Yes. Use the summary as a prompt for the AI Content Generator to expand the ideas into a full post or report.
Does it work on mobile?
Yes. The tool is fully responsive and works on phones, tablets, and desktops for reading on the go.
Is there a character limit?
There's no hard limit. Very large documents work better when you summarize them in sections for top accuracy.
How do I adjust the summary length?
Set the number of sentences you want to keep — fewer for a quick overview, more for a detailed summary.
