The Chrome extension

Papero Web Importer is a Chrome extension that saves papers and web pages to your Papero library while you read. It finds the reference on the page, shows it to you, and saves it to the collection you choose.

It saves references. It does not download PDFs or copy full texts.

Install it

1. Open Papero Web Importer on the Chrome Web Store and add it to Chrome. In Papero you can also press Import on the Library page, then From the web (Chrome extension).
2. Pin the extension to the toolbar, so its icon is always in reach.
3. Click the icon. The side panel opens beside the page.
4. If you are not signed in to Papero in this browser, press Sign in on papero.ai. New to Papero? Press Create a free account.

The extension uses the Papero session you already have in the browser. You do not type a password or a key into it.

Save from the side panel

1. Open a paper's page, then click the extension's icon. You can also right-click the page and choose Add this page to Papero.
2. The panel reads the reference from the page. Check what it found: the title, type, authors, journal, year, volume, pages and DOI. A retracted paper is marked Retracted, and a preprint Preprint.
3. Under Save to, pick My Library or one of your collections. Type in Search or create... to find a collection, or type a new name and choose the line that says Create and that name.
4. Press Save.

The panel then says Saved to your library, or Already in your library when you saved the paper before. Press Open in Papero to see it in your Library, or Save another.

Papero Web Importer can save:

• journal articles, by DOI;
• arXiv preprints;
• PubMed records;
• any other web page, as a web page source.

The panel cannot read Chrome's own pages, the Chrome Web Store or some Google sites. A tab that was open before you installed or updated the extension needs a reload: press Reload in the panel.

Save without opening the panel

The Add to Papero buttons: an Add to Papero button appears beside an article's title, and beside each DOI, arXiv and PubMed link on the pages you open. When the extension cannot match the title on the page, the button sits at the bottom right. One click saves the paper, and the button says Saved, or Already saved. The buttons are on by default.

The right-click menu: right-click a DOI, arXiv or PubMed link and choose Add this link to Papero to save that paper straight away. A small notice on the page says Saved to Papero.

A quick save goes where Save to in Button settings says: the last collection you used, or always My Library.

Button settings

Open the account menu in the panel's header and choose Button settings.

• Add to Papero buttons switches the buttons on or off on every site.
• Show on and the site's name switches them on or off for the site you are on. Sites you changed are listed under Turned off on, or Turned on on while the buttons are off everywhere. Press Remove to undo one.
• Save to chooses where quick saves go: Last collection I used or Always My Library.
• Open the panel shows the keyboard shortcut that opens the panel. The extension suggests Alt+Shift+P. Press Change to set your own in Chrome.

The account menu also has Theme (Light, Dark or System), Open Papero and Sign out.

Free and Plus

The extension works on Free and Plus. A saved paper goes into your library, where you can read, edit and cite it on both plans. To compare the plans, see pricing.

What it reads and sends

The extension talks to app.papero.ai and nothing else. It has no analytics, trackers or error-reporting service.

• While the buttons are on, it reads each page's citation and Open Graph tags, its title and address, and the addresses and text of its links, in your browser, to place the buttons. It does not read your browsing history or form fields. It places no buttons on papero.ai.
• Nothing leaves your browser until you click a button, use the right-click menu or open the panel. Even then, it sends only what it found, such as the DOI, title, address and site name.
• It keeps only its settings and the last collection you used, in your Chrome profile, where Chrome Sync may copy them to your other computers. It keeps no password, token or key.

A saved reference stays in your library like any other source, even if you uninstall the extension. The Privacy Policy sets out exactly what the extension reads and sends.

To see the extension in action, read the Chrome extension page on papero.ai. For more about your sources once they are saved, see Your library.
