Frequently Asked Questions


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.
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).
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

If your system does not meet these minimum requirements, you may be unable to log in to your Scholarcy account.
We use two different colours to highlight different ideas in the text. Gold highlight: main contributions made by the study. Blue highlight: important points and facts. You can easily navigate an article via the highlights by clicking on the Contributions and Important points links under the Highlight key menu.    

All data is transmitted via SSL and TLS in both directions. When you use the Scholarcy Library, Scholarcy Chrome Extension, Scholarcy API, or any of our demos, we process the following data:

  • your IP address. This data is logged and retained for 1 year.
  • The current URL in your browser. This data is logged and retained for 1 year.
  • The contents of the current page in your browser, or the contents of the file that you upload. This data is deleted immediately after processing - usually within 30 seconds.
  • If you are logged in to the Scholarcy Web Library, an authentication cookie that allows the Chrome Extension to store the summary content in your Web Library account.

When you sign up to the Scholarcy Library web app, we securely store your name, email address, and affiliation if you choose to provide it. This data is stored as part of your account, and you have control over its retention and deletion.

If you sign up to our mailing list (via separate opt-in), we use secure, third-party services to process your email address. Any other processing of your data is initiated by you, such as requesting a password reset.

We do not store credit card or other sensitive information. Our payment services are handled by Stripe. See our general Terms of Service, our Scholarcy Library Terms of Service, and our Privacy Policy for more information. You can also delete your account at any time and this will completely remove your information from our systems, apart from data required for legal compliance purposes.

We use Google Analytics to analyse the use of the Scholarcy Website, Scholarcy Library, and the Scholarcy Extension. For more details, see our Cookies Policy and our Privacy Policy.

Scholarcy streams the document into memory, and then permanently deletes it immediately after processing - usually within 30 seconds. It returns the extracted reading list, summaries, and references back to you. Use of these snippets in good faith for the purposes of dissemination of knowledge is covered by US Fair Use and recent UK Copyright Exemptions for Text and data mining for non-commercial research.
Scholarcy is a service that uses machine learning and artificial intelligence (AI) to read and condense academic papers into referenced summaries. Either upload your PDFs to Scholarcy, or give Scholarcy the public URL of a PDF and it will read the paper, break it down into readable chunks, and summarise it automatically. It will also read the bibliography and generate a link for each reference so that you can download cited papers. Scholarcy only works with public-access PDF URLs that are covered by relevant Creative Commons licences such as the Attribution ShareAlike and Public Domain licenses, as used by repositories such as arXiv.org and BMC. You must have lawful, legitimate access to any PDF that you upload. Please see our Terms of Service.
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.

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).

If nothing appears after uploading a document, try refreshing the page by hitting the reload button on your browser.

When you upload a PDF, Word document, or public URL to your Scholarcy Library account, you should see a progress bar and, after around 15 seconds, a new record should appear in your library, showing the title, author, date and other information depending on your settings.

If there's a problem, you'll normally see an error message. But if after refreshing the page, nothing appears in your library, or the entry is empty, then there might be a few possible reasons:

  • The PDF file contains no extractable text. We don't currently support scanned PDFs - if your articles have been scanned to PDF, you'll need to run it through some OCR software first. In future, we're aiming to provide this directly in the library.
  • The web URL is behind a paywall. You might be logged into your institutional repository, but Scholarcy can't see what you see when you read a paper in your browser. If the article is not open-access, try uploading the PDF directly.
  • The file is too large or too complex. Occasionally, some articles cannot be processed as their internal structure cannot be parsed. This can happen with PDFs with many images, or if you try to upload an entire book. For best results, break large files into smaller PDFs. For example, split a book into individual chapters and upload each one separately.

If you are still encountering problems, please send us the PDF so we can take a look.
