Tabbit vs Zen Browser
Two very different takes on the future of browsing. Zen gives you a calmer, privacy-first, open-source Firefox experience. Tabbit gives you an AI coworker that can read pages, fill forms, and run multi-step tasks on its own.
Choose Zen if you want an open-source, distraction-free browser. Choose Tabbit if you want the browser to actually do work for you.
