🐼 🐼 🐼 This is the new next-generation version of PaperPanda 🚀

PaperPanda helps you download scientific papers and do research.

You’ve probably run into this problem – you want to read a paper, but it’s locked behind a paywall.

Maybe you have access to it through your library or university, maybe it’s available to download for free through an open access portal,

maybe the author uploaded a PDF to a website somewhere – but how are you going to find it?

PaperPanda is here to help!

AI product read

Help users download scientific research paper PDFs by extracting the DOI from the current academic webpage and searching for open-access versions

Users encounter paywalled scientific papers they want to read. The extension automates finding free/open-access PDF versions by extracting the DOI and querying multiple academic repositories.

User navigates to an academic paper page → clicks the PaperPanda toolbar icon → extension extracts the DOI from the page using multiple detection methods (meta tags, data attributes, publisher-specific patterns) → opens the configured paper search URL (default: annas-archive.gd/scidb/) with the DOI appended → user can download the PDF from the resulting page

Target users: Students / Researchers / Academics / Anyone needing access to scientific papers

Cannot verify whether the destination service (paperpanda.app or annas-archive.gd) requires login or has paid features, as those are external services not bundled in the extension
Background.js is entirely commented out — no active background logic beyond the service worker registration

Monetization

No paid features detected

No paid features, subscriptions, or payment mechanisms found in the extension source code. No premium/upgrade/payment/stripe/license/billing keywords exist in any JS or HTML files. The 'paywall' keyword hits are from the store description describing the problem the extension solves (papers locked behind paywalls), not the extension gating features. The 'pro' keyword hits are false positives from German/French words containing 'pro' (e.g., 'probieren', 'problème'). The extension is fully free with all features accessible.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension requires no login to use its core workflow. It extracts DOIs from the current academic page via meta tags/data attributes and opens them in a new tab via a configurable open-access search URL. All settings are stored locally via chrome.storage.local/sync with no authentication. The only 'login' keyword hits in the source are from the store description describing the problem ("Save time navigating paywalls, logins and redirects"), not a login requirement.
