- An extension system more powerful than Chrome's, which supports for example rich adblockers that can block ads on Youtube. Also, it works on mobile, too
- Many sophisticated productivity, privacy, and tab management features such as vertical tabs, tab groups, container tabs, split tabs, etc. And now it also has easy-to-use profiles and PWA support just like Chrome
- A sync system which is ALWAYS end-to-end encrypted, and doesn't leak your browsing data or saved credentials if you configure it wrong, like Google's does, and it of course works on mobile too
- And yes, LLM-assisted summarization, translation, tab grouping, etc, most of which works entirely offline with local LLMs and no cloud interation, although there are some cloud enabled features as well
