KOReader Remote is a plugin for KOReader, the open source ebook reading software used on devices like Kindle and Kobo, that turns your phone's web browser into a remote control for your reader. The maker built it because they often set their Kindle down while reading in bed and got tired of reaching for it just to turn a page, so this lets a phone that is already in hand do the job instead. There is no app to install on the phone, no account, and no cloud service involved. Once installed on the reader, you start a small local server from KOReader's menu, then scan a QR code with your phone to open a local web page. From there you can turn pages with large touch controls, use keyboard arrow keys if your phone supports them, browse and search bookmarks and notes, open EPUB footnotes where detected, edit your active note draft, and adjust supported settings like frontlight brightness, warmth, and night mode. It also supports an OLED mode for a pure black interface and can recover the connection automatically after your reader wakes from standby. Setup requires copying the plugin folder into KOReader's plugins directory, either on a Kindle or Kobo, restarting KOReader, and starting the remote server from the Tools menu. Both devices need to be on the same local Wi-Fi network with direct device-to-device communication allowed, which some guest networks block. The plugin includes its own manual update checker with a stable and a dev channel, and it verifies release checksums before replacing itself, keeping the previous version as a backup. The author is explicit that this tool has no authentication: anyone who can reach the reader's local IP address and port can control it and see the open book's notes, so it is meant only for trusted local networks and should never be exposed to the internet.
