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

目标用户: 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

付费分析

未识别到付费功能

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.

需要登录: 否
登录理由: 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.
