Browser Extension

Save papers and web pages to your Jenni library from any browser tab.

FAQ ↓

The Jenni browser extension lets you save research papers and web pages directly to your library while you browse. It detects metadata automatically and files sources into the collections you choose.

Getting Started

  1. Install the extension from your browser’s extension store
  2. Pin it to the toolbar for quick access
  3. Sign in with your Jenni account

Once signed in, the extension stays connected until you log out.

Saving Papers and Web Pages

Navigate to a page you want to save, then click the extension icon in the toolbar. Jenni detects the page metadata (title, authors, abstract, DOI, publication date) and displays it in a popup. Select one or more collections, then click Add to Library.

A progress indicator shows the save status. Once complete, an Open in Jenni link appears so you can jump straight to the source in your library.

PDF vs Non-PDF Pages

Compatibility

Supported Content

The extension works with major academic publishers and repositories:

For these sources, the extension extracts structured metadata and downloads the associated PDF when available.

Unsupported Pages

The extension does not work on:

On unsupported pages, the extension icon remains inactive or displays a notice that the page cannot be saved.

Floating Popup

On supported pages, a floating popup can appear in the bottom-right corner of the browser window. It shows:

You can minimize the popup to keep it out of the way while you continue reading. Press Esc or click the close button to dismiss it entirely.

Collections

When saving a source, you can select which collections to add it to. The collection selector shows your existing library collections and lets you create a new one on the fly. Type a name and confirm.

A source can be added to multiple collections in a single save action.

Metadata Extraction

The extension gathers metadata using a priority order:

  1. PDF processing: if the page serves a PDF, Jenni extracts identifiers and bibliographic data from the document itself
  2. Identifier-based lookup: DOIs, PMIDs, and PMCIDs are resolved against external databases for complete records
  3. HTML extraction: structured data in the page’s HTML (meta tags, schema.org markup, citation tags) is parsed as a fallback

The most reliable metadata comes from pages with a DOI. Pages without any identifiers rely on HTML extraction, which varies in completeness.

Troubleshooting

ProblemSolution
No metadata detected on a supported pageReload the page and try again. Some pages load metadata asynchronously. If the issue persists, copy the DOI and add the source manually in Jenni.
PDF not saving (reCAPTCHA or access wall)The publisher may require authentication or CAPTCHA completion before serving the PDF. Complete the verification in your browser, then try saving again.
Extension not appearing in the toolbarCheck that the extension is installed and enabled in your browser’s extension settings. Pin it to the toolbar if it is hidden in the overflow menu.
Authentication issuesSign out of the extension and sign back in. Clear the extension’s stored data in your browser settings if the problem continues.

Frequently Asked Questions

How do I install the Jenni browser extension?
Install it from your browser’s extension store, pin it to the toolbar for quick access, and sign in with your Jenni account. It stays connected until you log out.
How do I save a paper to Jenni from my browser?
Navigate to the paper’s page and click the Jenni extension icon in your toolbar. It detects the page metadata automatically. Select a collection and click Add to Library.
What sites does the Jenni browser extension work with?
It works with ArXiv, Nature, JSTOR, bioRxiv, PubMed, Lens.org, direct PDF links, and any page with a DOI, PMID, or PMCID in its metadata. It does not work on YouTube, Figma, Google Maps, or Chrome internal pages.
Why isn't the extension detecting metadata on a page?
Try reloading the page, as some sites load metadata asynchronously. If it still doesn’t work, copy the DOI and add the source manually in Jenni. Pages without any identifiers rely on HTML extraction, which varies in quality.
Does the browser extension save the PDF automatically?
Only if the URL points directly to a PDF file. For standard web pages (journal summaries, HTML articles), Jenni saves metadata only. You can attach the PDF manually afterward from your library.
Can I save a paper to multiple collections at once?
Yes. When saving a source, the collection selector lets you choose multiple collections in a single save action. You can also create a new collection on the fly.
The extension won't save a PDF behind a paywall. What do I do?
The publisher may require authentication or CAPTCHA completion before serving the PDF. Complete the verification in your browser first, then try saving again through the extension.
