The old definition of safe

Why traditional secure browsers still leave you working alone

Most “secure browsers” stop at blocking trackers. They do not help you finish tasks, manage sensitive contexts, or control what AI sees.

Security is passive

You still manually clear cookies, review permissions, and copy sensitive data between apps.

AI is locked in a sidebar

Chatbots answer questions but cannot act on pages, fill forms, or enforce your privacy rules.

Work and life collide

Without isolated workspaces, personal tabs, banking sessions, and work research live in the same messy window.

One model, one vendor

You are forced into a single AI provider with limited transparency about what data leaves your browser.
