what is kindlefetch.koplugin fr?

KindleFetch is a plugin for KOReader, the alternative reading app people install on Kindles and other e-readers. It lets you search for and download books from Anna's Archive and Library Genesis directly on your device, without needing a computer or transferring files by cable. Once installed, you get a search box built into the reader's interface. You type in a title, author, or keyword, browse the results with cover images shown, and tap a book to start the download. A progress bar shows how the download is going, and it runs in the background so you can keep reading while it finishes, or cancel it if you change your mind. The plugin can also handle several file types beyond ebooks, including comics, documents, and images, and it lets you set preferred languages and formats so search results are filtered to what you actually want. Under the hood, the plugin caches search results, cover images, and mirror site addresses so it does not have to repeat the same network requests every time, which keeps things fast and reduces load on the source sites. It also keeps its own copy of curl, the tool used to download the actual files, up to date automatically, and it can check for and prompt you to install new versions of the plugin itself. Installation is done by downloading a release from GitHub and unzipping it into KOReader's plugins folder. The author notes it works best on the stable release of KOReader rather than nightly builds, which have caused issues in the past. The project is written in Lua, the same language KOReader plugins are built in, and it is aimed at Kindle and e-reader owners who want a faster way to get books onto their device.
