Scholarcy Summarizer

Chrome Extension

We have a hard limit of 400 pages per document. We generally don't support processing an entire book - it is much better to split a book into chapters and upload each chapter separately. This also makes sense from a reading perspective - each chapter will have its own themes and topics.
Scholarcy Library, Chrome Extension, and our other tools, need a modern operating system and web browser to run correctly. Please check that your system meets the minimum requirements listed below:

Operating system

  • OS X: 10.15 Catalina or higher
  • Windows: Windows 10 version 1903 or higher
  • iOS/iPad: iOS or iPadOS 11 or higher
  • Linux: Ubuntu 16.04 LTS or higher

Web browser

  • Chrome version 98 and above
  • Edge version 16 and above
  • Firefox version 90 and above
  • Safari version 15.6 and above
  • Opera version 48 and above
If your system does not meet these minimum requirements, you may be unable to log in to your Scholarcy account.
While our algorithms do a good job distilling the majority of documents into their key facts and findings, sometimes they struggle! If you find that a particular document does not upload, try one of the following:
  • If the document is a scanned PDF image, run it through OCR software first. There are both free and commercial software available for this.
  • If the document is a complete book, try breaking it down into separate chapters, and upload one chapter at a time
  • If the document is very large or many pages long, try breaking it down into smaller files and upload each of these separately
  • If the document contains many figures and images, try switching off Extract Figures in Settings > Import.
  • Send us the PDF and we'll investigate
Do you have other browser extensions installed? If so, try disabling them, or open Scholarcy Library in a new Incognito window (Chrome) or Private window (Safari, Firefox, Edge).

For best results, Scholarcy needs access to the full text of the article. If the article is behind a paywall or institutional log in, unfortunately our cloud-based services cannot access it. In this case, it is best to upload the PDF of the article instead using our Article Summarizer  - click on the Upload document button and navigate to the PDF on your local machine.

You can also upload files directly to your Scholarcy Library.

In all cases, the PDF must contain readable text. Currently, we are unable to handle scanned PDFs that are essentially just pages of images, and need to be converted to readable text using OCR software first. However, we hope to have an OCR option available soon.

To extract the references, Scholarcy usually needs access to the full text of the article or chapter, unless the publisher has made the references openly available with the abstract. Otherwise, the article/chapter needs to be open access, or you need to upload the PDF directly, if you have legitimate access to it. Reference extraction is available within the Chrome Extension, if you are logged into your Scholarcy account, or within Scholarcy Library. Within the summary flashcard for the article, click the Download button in the References tab to download them as either a RIS or BibTeX. In Scholarcy Library, you can also export the references in bulk from a collection of articles.    
Our Chrome Extension and Web Library provide a number of options, for example, the summary length or whether to extract images.
Not everyone wants to install another extension, so you can try out Scholarcy without commitment with our article summariser and Flashcard creator. The Flashcard generator can also be used to preview cards before you save them to your Library when you sign up for a Scholarcy account.

Image/figure extraction is disabled by default both in the Chrome Extension and Scholarcy Library web app. You can enable it in the Chrome Extension by choosing Options, and in the Library by choosing Settings, select the Import tab, and then sliding the Extract figures slider to the right.

Normally, you should see a 'Save to Library' button in the Chrome extension when you are logged into your Scholarcy Library account. If not, you may need to log out from Scholarcy Library, clear your cookies, and log in again. Log out from your Scholarcy Library. Go to chrome://settings/siteData?search=cookies and search for Delete cookies from and and then log in to your Scholarcy Library account again. You may also need to temporarily disable any Adblocker extensions you have running while you carry out this process.
Most of the time taken is loading the PDF or Word document from the server where it resides, or uploading the document from your computer. If you are using the Scholarcy Web Library, and are uploading a large document with a slow internet connection, it may take a minute or two before the summary card appears in your library. Once it has the PDF, Scholarcy takes around 5-20 seconds to turn the PDF into data. However, some PDFs that live on a slow server, or contain many images, may take more time to process. If you don't require figure extraction:
  • If using the Chrome Extension, right-click on the Scholarcy icon in the Chrome toolbar (or via chrome://extensions/, choose Options, and uncheck 'Extract figures'.
  • If using the Library app, choose Settings and uncheck 'Extract figures'
It's also possible that the user interface hasn't automatically refreshed, so you can reload the page and the summary card should then appear in your library.
