Open Access Button helps you download the PDFs of the papers you need.

One Button. Every Paper.™

Open Access Button finds free, legal versions of academic papers when paywalls get in the way. If the research exists open, the OAB will find it for you.

When you view a scientific paper, OAB detects its DOI (Digital Object Identifier) and checks whether there is available legal open access version.

Click the orange Open Access Button extension to download the PDF.

Knowledge yearns to be free.

AI 产品解读

A browser extension that detects DOIs (Digital Object Identifiers) on academic paper pages and redirects users to configurable external services to find free, legal open-access versions of those papers

Researchers and students frequently encounter paywalls when trying to access academic papers. This extension bypasses paywalls by finding legal, free open-access versions of the same papers from repositories and open-access sources.

1. User visits a page containing an academic paper on any publisher site 2. User clicks the Open Access Button extension icon in the browser toolbar 3. Extension injects a script to extract the DOI from meta tags or page-specific elements 4. Extension opens a new tab to the configured paper download service (default: https://annas-archive.gd/scidb/) with the DOI appended 5. The external service resolves the DOI and provides access to a free/open-access version of the paper

目标用户: Researchers and academics / University students / Librarians / Healthcare professionals / Policy makers needing access to evidence-based research

Cannot verify the behavior of the default external service (annas-archive.gd/scidb/) or other configurable services—they may have their own auth/payment requirements
background.js is empty (0 bytes), so no background processing logic to analyze
The extension's options page allows arbitrary custom URLs for the paper search service, meaning the actual behavior depends on the user's chosen service

付费分析

未识别到付费功能

The extension is completely free with no paid tiers, feature gating, or payment processing. The heuristic-detected keywords 'paywall' and 'subscription' appear only in description text describing the PROBLEM the extension solves (accessing papers behind paywalls), not the extension's own pricing. extension-descriptions.md explicitly states: 'Free to Use: Completely free with no hidden costs or premium tiers' (line 37) and 'No subscriptions, no paywalls' (line 88). No Stripe, billing, license, or payment API calls exist in the source code. The external services the extension redirects to (e.g., annas-archive.gd, openaccessbutton.org) may have their own pricing, but the extension itself does not gate any features behind payment.

登录理由: No login UI, authentication flows, OAuth, or account creation exists in the extension. The extension uses chrome.storage only for local preferences (paperURL, showRating). The core workflow—extract DOI from the current page and redirect to an external paper download service—works entirely without any account or authentication.
