Jack Cheng Builds Browser Without Tabs

The browser’s real idea is not “tabs are bad,” but that AI makes interfaces personal and composable.

• –The agent pane turns browsing into an active editing workspace rather than a passive page-viewing tool.
• –Multiple model providers let users match different models to research, writing, and revision tasks.
• –Peek mode reduces context switching by making pages temporary and disposable.
• –Its bespoke design highlights a coming split between mass-market browsers and highly personalized AI workspaces.
