Mochi is a charming, open-source browser extension designed to bring a little joy to your daily browsing routine. Created by developer Koustav Roy, Mochi places a tiny, animated cat companion directly onto your browser tabs to hang out with you while you work, study, or surf the web.

Unlike busy modern widgets, Mochi is intentionally quiet and non-intrusive. It is not a productivity tracker, an organizer, or a notification machine. Instead, it is purely a friendly visual companion for your browser. You can choose from 20 local cat styles, drag your little friend anywhere on your screen, and enjoy a consistent experience as the cat stays in the exact same spot across all of your tabs.

Built with absolute privacy in mind, Mochi requires no user accounts, displays no advertisements, uses no tracking analytics, and does not collect or send any remote data. It is a simple, lightweight, and delightful addition to your browser window.
