ChatGPT has a file upload limit and requires a Pro subscription for PDF uploads. ChatPDF charges per document after a small free tier. NexTools gives you AI PDF summarization free up to 20 tasks/month — no account needed, no per-document fees. We extract clean text from your PDF before sending it to AI, which produces more accurate summaries than raw upload methods.
Any text-based PDF works — research papers, academic articles, business reports, legal contracts, financial statements, technical documentation. Scanned PDFs (image-only) cannot be summarized because they contain no extractable text.
Accuracy is high for well-structured documents. The AI captures main arguments, key findings, and conclusions accurately. For highly technical content (math-heavy papers, code-heavy technical docs), the summary captures the narrative but may not reproduce formulas or code precisely.
Your PDF is uploaded over HTTPS and processed immediately. We extract text to generate the summary, then delete the file from our servers. We don't store your document content after processing.
Free users can summarize PDFs up to 20MB. Very long documents (200+ pages) may be summarized in sections. If a document exceeds the context limit, we summarize the first portion and note where the summary ends.
Yes. Our AI model supports most major languages including French, Spanish, German, Chinese, Japanese, Portuguese, and more. The summary will be generated in the same language as the document.
