ZLibrary book search, preview, and download Chrome extension

Provides quick access to search and download books from ZLibrary directly from the browser toolbar without visiting the website manually

User clicks the extension icon, types a book title in the search form, submits the search. The extension queries ZLibrary's API (/eapi/book/search) and displays results with cover images, metadata, and download/read-online buttons. To download, users must first log in to ZLibrary via the login button (opens z-library.sk/login.php in a new tab). After login, the extension reads authentication cookies (remix_userid, remix_userkey) and enables the download button. Downloads are triggered via ZLibrary's file API and Chrome's downloads API. Results persist across popup reopens via session storage.

Target users: Book readers and researchers who use ZLibrary / Users seeking quick book search and download from browser

Code is heavily minified (single line JS files), making exact line-level analysis difficult
Cannot verify if ZLibrary's download limits are tied to their own paid plans (external to extension)
The extension is open source (github.com/balldk/zlib-extension) which could provide additional clarity but was not available for inspection

Monetization

No paid features detected

No payment, billing, subscription, premium tier, or upgrade logic found in the extension source code. The 'subscribe' keyword hits are Svelte framework store subscriptions (not billing). The 'pro' keyword hits are generic JS identifiers in minified code, not paid feature references. The extension does not gate any features behind payment. ZLibrary itself may have its own plans, but the extension itself does not implement or reference any paid features.

Confidence: 85
Payment platform: --
Source: AI / High
Login required: Yes
Reason: Users can search without login, but downloading books requires a ZLibrary account. The extension reads remix_userid and remix_userkey cookies from z-library.sk. The download button is disabled with tooltip 'You must login to download' when not authenticated. Login is performed on the ZLibrary website (https://z-library.sk/login.php), and the extension reads the resulting cookies.
