# Research Paper Summarizer

Upload a scientific article or preprint and get a structured summary — research question, method, key results with their actual numbers, the authors' conclusion and the limitations they admit. Then ask follow-up questions and get answers that point to the page.

## Key facts

- Reads the full paper, not just the abstract — results tables and the discussion included.
- Summary follows the structure researchers expect: question → method → results → conclusion → limitations.
- Every key number comes with its page reference, e.g. (p. 6), so you can check it in the PDF.
- Ask follow-ups such as “What was the sample size?” or “Which datasets were used?”.
- Free, no account, up to 300 pages; scanned papers are read with OCR.

## What the summary covers

A good research-paper summary is not a shorter abstract. Abstracts are written to sell the paper; they often omit the sample size, the comparison condition or the caveats. When you pick the **Research paper** document type, the AI is instructed to report:

- **Research question or objective** — what the authors set out to show.
- **Method** — study design, data or materials, sample size, main analysis.
- **Main results with the actual figures** — effect sizes, accuracy, p-values or confidence intervals when the paper gives them.
- **The authors' conclusion**, stated exactly as strongly as the paper states it (no “proves” where the paper says “suggests”).
- **Limitations** the authors acknowledge, plus anything obviously missing (e.g. no control group).

Because the PDF is read page by page, facts are tagged with the page they come from. That makes the summary something you can verify, not just trust.

## How to summarize a research paper

1. **Upload the PDF** — Drag the paper onto the tool above. Publisher PDFs, arXiv preprints and scanned journal pages all work.
2. **Keep “Research paper” as document type** — It is preselected on this page. Choose Detailed for a reading note or Short for a screening decision.
3. **Read the structured summary** — Results come with page references; click through to the page in your PDF viewer to check a figure.
4. **Ask follow-up questions** — Switch to Ask questions and ask about anything the summary skipped: datasets, hyper-parameters, inclusion criteria, funding.
5. **Export your note** — Copy the summary or download it as Markdown for your reference manager or notes app.

## Example of what you get

*Illustrative example based on a fictional paper, to show the format:*

> **Objective.** Test whether a 10-minute daily spaced-repetition routine improves vocabulary retention in adult learners (p. 1).
> **Method.** Randomised controlled trial, 214 participants, 8 weeks; control group used the same app without scheduling (p. 3).
> **Results.** Retention after 30 days was 71% vs 54% in the control group (p. 6); the effect was smaller for participants over 60 (p. 7).
> **Conclusion.** The authors conclude spaced repetition “substantially improves” retention for this population (p. 9).
> **Limitations.** Self-reported practice time; single language pair; no follow-up beyond 30 days (p. 9).

## When this tool saves the most time

- **Literature screening** — decide in a minute whether a paper deserves a full read.
- **Journal clubs and seminars** — arrive with the method and the numbers, not just the headline.
- **Writing a related-work section** — collect consistent notes across dozens of papers.
- **Reading outside your field** — ask the AI to explain a method in plain language, with the page where it is described.

> **Got a stack of papers?** — Upload the first one now — the summary is ready in about ten seconds.

## Tips for better results

- **Use the publisher PDF or the arXiv PDF**, not a screenshot. Native text gives cleaner tables than OCR.
- **Ask about tables explicitly.** Tables are extracted as text; asking “What are the values in Table 2?” makes the AI focus on them.
- **Check numbers that matter** using the page reference. AI can misread a table column, especially in two-column layouts.
- **For a reading list**, choose *Key points* — you get the 5-10 findings that matter with their figures.

## Limits to keep in mind

The tool reads text, not images: values that only exist inside a chart image will not be captured unless the chart has a text layer. Equations are extracted as plain text and may lose formatting. A summary is a reading aid — for a systematic review or a clinical decision, always confirm the extracted figures against the paper.

## FAQ

### Can it summarize papers from arXiv, PubMed or IEEE?

Yes. Any PDF you can download works: arXiv preprints, PubMed Central articles, IEEE, ACM, Springer or Elsevier PDFs. Paywalled papers need to be downloaded through your institution first — the tool does not fetch papers from links.

### Does it read the whole paper or only the abstract?

The whole paper. Every page with a text layer is read, including results, discussion and appendices. Papers longer than one AI pass are read in parts and merged.

### Can I get the summary in another language?

Yes. Choose an output language: for example, summarize an English paper in Spanish or a German paper in English. Technical terms are kept when a translation would be ambiguous.

### Will the summary invent results?

The AI is instructed to report only what the paper states and to cite pages. Errors are still possible with complex tables or ambiguous wording, which is why each key figure has a page reference you can check.

### Is my unpublished manuscript safe?

The PDF is deleted right after text extraction, the extracted text is erased after 60 minutes, and nothing is used to train AI models. For highly confidential drafts, read our privacy policy before uploading.
