Lightweight Browser for Windows
A fast, low-memory browser for Windows 10 & 11 that uses AI to organize tabs, automate tasks, and keep your PC running smoothly.
THE PROBLEM
Why most Windows browsers feel heavy
RAM disappears fast
Chrome and Edge can consume gigabytes of memory, slowing down laptops with 8 GB or less.
Horizontal tabs overflow
Dozens of tiny tabs across the top make it hard to find what you need and waste screen space.
Extensions slow things down
Every AI assistant, blocker, and manager adds another process running in the background.
HOW TABBIT STAYS LIGHT
Built to be a lightweight browser for Windows
Vertical tabs save space
A slim sidebar shows full page titles, smart groups, and workspaces—so you keep more pixels for actual work.
AI handles the clutter
Tabbit auto-groups tabs by topic and summarizes open pages, so you spend less time managing windows.
Agent mode does the work
Let the browser fill forms, collect data, and run repetitive tasks in isolated tab groups while you keep browsing.
One-click migration
Import bookmarks, passwords, cookies, and extensions from Chrome or Edge in minutes, not hours.
