What file formats are supported for upload?

PapersFlow accepts PDF, DOCX, and plain text files. For PDFs, it uses GROBID to parse the document structure, so papers with standard academic formatting (two-column, IMRaD structure) produce the best results. Scanned PDFs without an OCR text layer will be processed with built-in OCR, though quality depends on scan resolution.

How accurate are the summaries compared to the original paper?

In our internal evaluations, summaries correctly capture the primary research question, methodology, and main findings in over 90% of cases for empirical papers. The most common errors involve oversimplification of multi-step methods or missing secondary outcomes. Every summary includes section references so you can spot-check against the original.

Is the summary based on the full text or just the abstract?

When you upload a PDF or the full text is available, PapersFlow processes the entire document including methods, results, discussion, and supplementary materials. If only the abstract is available (e.g., when importing by DOI without a PDF), PapersFlow clearly labels the summary as abstract-only so you know its limitations.

Can I summarize a batch of papers at once?

Yes. You can select multiple papers from your library or upload several PDFs simultaneously. PapersFlow processes them in parallel and produces individual summaries plus a comparative synthesis that highlights common themes, methodological differences, and conflicting findings across the batch.

Can I customize what the summary focuses on?

Yes. You can specify a focus area like 'methodology only' or 'results and limitations' before generating the summary. You can also provide a research question, and PapersFlow will emphasize aspects of each paper most relevant to your specific inquiry rather than giving a generic overview.

Tool

AI Paper Summarization

Get structured summaries of research papers in seconds. PapersFlow's AI reads full texts — not just abstracts — to extract methodology, key findings, and limitations.

PapersFlow summarizes papers by reading the full text, extracting structured information about methodology, findings, and limitations — not just paraphrasing the abstract.

Your advisor just sent you a reading list of 53 papers for your qualifying exam. Each paper is 8-15 pages of dense academic prose, and you need to understand not just what they found, but how they did it and why it matters for your own work. At 30-45 minutes per paper, you are looking at 30+ hours of reading before you can even begin to see the connections between them. And if you are working across disciplines -- say, applying NLP techniques to clinical data -- half the papers use terminology and conventions you are still learning.
