Research Paper Summarizer
Import a paper's PDF, choose the sections that answer your question and summarize them into notes you can use. The file is read in your browser, never uploaded.
To summarize a research paper, import its PDF, skip the abstract (it is already a summary) and summarize the methods, results and discussion separately with Key Points. Then check every number against the paper and cite the paper itself.
Quick facts
- Files

- Cost
- Free account: 1,000 words in the first month, then 300 a month. No card.
How it works
- 1Import the paper's PDF. Drop it on the box. Journal and preprint PDFs have a text layer and are read instantly.
- 2Keep one section. Delete the references and everything except the section you need: methods, results or discussion.
- 3Summarize with Key Points. Key Points pulls out claims and findings. Short is the free option for a quick gist.
- 4Check the numbers, cite the paper. Confirm effect sizes and sample sizes against the PDF. Cite the paper, never the summary.
The abstract is already a summary
Every paper comes with a summary written by its authors: the abstract. Running the whole paper through a summarizer mostly reproduces it. What a summarizer adds is the detail the abstract leaves out, and that lives in specific sections. The methods tell you who was studied and how, which decides whether the results apply to your question. The results hold the actual numbers. The discussion is where authors admit limitations, which abstracts rarely mention. Summarize those sections separately and you get something the abstract does not give you.
Which section to feed for what you need
Writing a literature review? You need the research question, design, sample and main finding, so summarize the methods and the first part of the results. Deciding whether to trust a finding? Summarize the limitations part of the discussion. Preparing for a journal club? Summarize the results and discussion and read the methods yourself. Most papers follow the IMRaD structure (introduction, methods, results and discussion), so the headings tell you where to cut. The table below lays it out.
Two-column PDFs, equations and tables
Many journals and conference templates use two columns. The importer reads text in the order the PDF stores it, which is usually one column then the next, but skim the imported section to make sure it reads in order. Equations rarely survive as text, because a PDF stores mathematics as positioned symbols rather than as formulas, so expect fragments wherever there was maths and delete them. Results tables come through as runs of numbers without their layout. Read tables in the PDF itself and summarize the prose that interprets them.
Building a literature matrix from summaries
Researchers keep a matrix with one row per paper and columns for question, method, sample, main finding and limitations. Key Points summaries fit straight into those columns. Summarize the methods into one cell and the results into another, then add the limitations from the discussion. Write the full citation in the first column as you go, from the paper rather than from memory. A matrix built this way makes gaps and disagreements between studies obvious, which is the point of a literature review.
Summaries are notes, not sources
Never cite a summary, and never copy one into your own writing. A summarizer can compress a hedged claim ("associated with, in this sample") into a stronger one ("causes"), can drop the confidence interval that made a result interesting, and cannot see the figures. Use the summary to decide what to read closely and to remember what you read. Every number, quotation and claim in your work should be checked against the paper and cited to the paper. Use only papers you have legitimate access to, through your library, open access or the authors.
Long papers and review articles
A typical empirical paper's methods or results section fits in one run on most plans. Each summary covers 1,000 words in a free account's first month, 300 after that, and Starter 1,200, Pro 2,500, Ultra 6,000 on paid plans. Review articles and theses are longer; work section by section and then summarize your section summaries for an overview. The importer reads up to 30 pages of a PDF; for a longer thesis, use a PDF tool to split out the chapter you need.
Who it's for
| You need | Summarize | Style |
|---|---|---|
| A literature-review entry | Methods and the start of the results | Key Points |
| To judge whether a finding is solid | Limitations in the discussion | Medium |
| A journal-club briefing | Results and discussion | Bullets |
| A quick yes or no on relevance | Introduction (last paragraph) and conclusion | Short |
| The authors' overall argument | Discussion | Long |
| Part of the paper | Comes through as | What to do |
|---|---|---|
| Body text | Clean paragraphs, page numbers removed | Summarize section by section |
| Two-column layout | Usually one column, then the next | Skim for order before summarizing |
| Equations | Scattered symbols | Delete them |
| Results tables | Numbers without layout | Read in the PDF; summarize the text about them |
| Figures | Skipped (captions kept) | Look at them yourself |
| References | Long list of citations | Delete before summarizing |
Frequently asked questions
Can I summarize a research paper for free?
Yes. Import the PDF free; a free account summarizes 1,000 words a run in its first month and 300 after that in the Short style. Key Points and Bullets are PRO styles.
Should I summarize the whole paper at once?
Usually not. The abstract already summarizes the whole paper. Summarize the methods, results and discussion separately to get the detail the abstract leaves out.
Can it read two-column journal PDFs?
Yes. Text is read in the order the PDF stores it, usually column by column. Skim the imported text for order, and delete equation fragments before summarizing.
Can I cite the summary in my paper?
No. Cite the original paper and check every number and claim against it. A summary can drop qualifications or strengthen hedged claims.
Does it read figures and tables?
Figures are skipped and tables arrive as numbers without layout. Read those in the PDF and summarize the text that interprets them.
Is the paper uploaded anywhere?
No. The PDF is read in your browser. Only the section you summarize is sent, and it is not used to train AI models.
