What this Text Summarizer does

This Text Summarizer creates a shorter version of pasted text or extracted document text by selecting sentences that appear important based on frequency, sentence position, and keyword overlap. It can also produce a short list of key points.

It works with pasted text, TXT files, Markdown files, text-based PDFs, and modern Word .docx documents. It is designed for quick review, study support, note compression, and document scanning.

File upload note

PDF extraction works best for digital PDFs that already contain selectable text. Word extraction works best for modern .docx documents. Scanned PDFs, image-only PDFs, old .doc files, heavily formatted academic articles, mathematical papers, tables, figures, footnotes, and two-column layouts may extract imperfectly.

Always review the original document before relying on the summary.

Important privacy and accuracy note

This tool is designed for browser-based text extraction and summarization. Do not upload confidential, personal, legal, medical, financial, academic-integrity-sensitive, unpublished, proprietary, or sensitive documents unless you understand the privacy model and risks.

This is an extractive summarizer. It reuses selected sentences from the original text and may miss nuance, context, methodology details, limitations, or specialized meaning.

FAQ

Can I summarize a PDF?

Yes, if the PDF contains selectable text. Scanned or image-only PDFs usually require OCR and may not extract useful text.

Can I summarize a Word document?

Yes, upload a modern Word .docx file. Legacy .doc files are not supported in this browser version.

Does this Text Summarizer use an AI API?

No. This MVP version uses a browser-based extractive method. It does not call an external AI API.

Can this replace reading the original document?

No. A summary can help you review text faster, but it may miss important details. Always review the original source before making academic, professional, legal, medical, or financial decisions.
