About koreader
KOReader is a free, AGPL 3.0 licensed document viewer written in Lua that runs on e ink readers from Cervantes, Kindle, Kobo and PocketBook, on reMarkable, and on Android and desktop Linux, aimed at readers who want broader format support, finer typesetting control and better performance than the reading software shipped with their device.

About Languine
Languine is a self hosted, Vercel native localization tool for application text. It lives in the TypeScript and Vercel ecosystem, and it uses a CLI plus a dashboard to translate project strings with an AI model. The concrete problem it solves is repetitive manual localization: a team can point the CLI at a project, create a project record on its own deployment, and run a translate command instead of maintaining every language file by hand.
