Guides
Paste an article, report, or any long block of text and get an AI-generated summary — choose how long you want it and whether you'd rather read flowing prose or a scannable bulleted list.
How to use it
- Paste the text you want to summarize (200 to 20,000 characters).
- Choose a summary length: short (2-3 sentences), medium (one paragraph), or long (2-3 paragraphs).
- Choose a format: paragraph for flowing prose, or bullet points for a scannable list of the key points.
- Click Summarize.
Paragraph vs. bullet points
- Paragraph reads naturally and works well when you want to drop the summary straight into a document, email, or newsletter blurb.
- Bullet points breaks the same content into a scannable list — better for skimming a long report quickly, or pulling out the key takeaways for a meeting or a social post.
Both formats cover only what's actually in the text you pasted — the summarizer doesn't add outside facts or its own opinion.
Tips
- Longer, more detailed source text generally produces a more accurate summary — a single paragraph doesn't leave the model much to condense.
- If the summary misses something important, try the "long" length first — a shorter target sometimes drops a secondary point to stay concise.
- For a summary you can share or embed without regenerating it, copy the output text — like every AI-generated tool on this site, the result isn't reproducible from a shared link (it's non-deterministic, so a link would just spend credits regenerating a different answer).
Is my text stored anywhere?
Your pasted text is sent to an AI provider to generate the summary, then discarded — it isn't logged, stored, or used to train anything. See the third-party data badge above the tool for details.
Can I summarize a webpage or a PDF instead of pasted text?
Not directly — paste the text itself. For a PDF, extract the text first (most PDF readers support copy-paste, or use a PDF converter to get plain text out first).
