Frequently Asked Questions

To identify duplicate items in your Library, follow these steps:

  1. Navigate to the library or folder that you want to deduplicate.
  2. Slide the Show duplicates slider to the right. This may process for a few seconds.
  3. Sort items by Title by clicking on the up or down arrow next to the Title column heading.
  4. You will see duplicate items grouped by title.

You can then use the Move/Export/Delete button in the top menu to move duplicate items to another folder, or delete them.

If you log into your Zotero web account and go to https://www.zotero.org/settings/keys

  1. Make a note of your Zotero user ID as shown on that screen:

2. Then click the Create new private key link (https://www.zotero.org/settings/keys/new) where you can create an API key and allow Scholarcy to read your Zotero library and optionally shared groups.

3. Click Save Key. The generated key will then be displayed. Please copy this key somewhere safe.

4. In the Import panel, under From the Web or cloud storage, select Zotero. You will need to copy your userID from Step 1 into the userID field in Scholarcy Library, and the API key from Step 3 into the API key field here:

5. If these details are correct, when you click Save you will be able to connect and import PDFs from your Zotero web library. You only need to follow the above steps once.


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.

You can export up to 100 flashcards to Excel, Word, Markdown, Powerpoint or RIS (Endnote, Zotero) at a time.

To do this, go to the Settings menu and click View, and then change the Rows on page to 100. Then click the   Save changes button.

Then go to your folder or Library, click the Move/Export/Delete button, and click Export documents

Export documents

Click the checkbox at the top to select all articles, and then click the Export selected button.

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.

No. Scholarcy does not distribute any original papers or the summaries of these papers.

When it comes to copyright, think of Scholarcy as the same as any reference management tool, Google Drive or Dropbox. The paper is uploaded to the user’s personal account for their personal use for research purposes. And we go one step further – the original paper is not stored. It is summarised and the original PDF is deleted. There is no way for anyone else to access the paper.

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 PDFs into their key facts and findings, sometimes they struggle! If you find that a particular PDF does not upload, try one of the following:

  • If the PDF is a scanned image, run it through OCR software first. There are both free and commercial software available for this.
  • If the PDF is a complete book, try breaking the PDF down into separate chapters, and upload one chapter at a time
  • If the PDF is very large or many pages long, try breaking it down into smaller files and upload each of these separately
  • If the PDF 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).

Log into your Scholarcy account and go to the Subscription page to manage your account. You have full control over your subscription and can pause and restart it at any time.
