Free Extractive Text and Article Summarizer
Shorten pasted notes or drafts by selecting the strongest original sentences with a simple local scoring method.
Text and article summarization without unsupported claims
This tool accepts pasted plain text and selects important original sentences using repeated-term scoring. It is useful for reviewing notes, article drafts, and passages, but it is not a generative AI model and does not rewrite the source.
The page does not open PDF files, fetch a website URL, summarize an entire book automatically, or provide an unlimited AI context window. For a PDF you are permitted to process, copy selectable text from the document and paste only the relevant section. If the PDF is a scan, use Image to Text OCR on appropriate page images first, then verify the extracted text before summarizing it.
Review every extractive summary
Because the method favors repeated words, it can miss a rare but critical warning, exception, date, or conclusion. Compare the output with the full source and never rely on an automatic summary for legal, medical, financial, academic, safety, or policy decisions.
About this tool
A quick summary can help you review a long note before editing, but it should not replace human judgment. This tool uses a simple extractive method: it scores sentences by repeated meaningful words and returns selected original sentences. It does not invent new wording, make claims, or understand context like a person would.
How to use it
- Paste the text you want to reduce and choose how many sentences the summary should contain.
- Click summarize and compare the selected sentences against the original.
- Edit the result before publishing, especially if the source includes names, numbers, promises, or sensitive detail.
Tips and common mistakes
- Short, repetitive source text may produce a weak summary because there is not enough signal to rank.
- Use the result as a draft outline, then rewrite it for tone, accuracy, and flow.
- Never summarize legal, medical, financial, or policy text without checking the full source.
