Why Tabbit
If your work happens inside a browser, Tabbit is the tool that actually lives there.
Tell Tabbit what to do in plain English. It reads pages, fills forms, operates across sites, and returns structured results while you keep working.
Press @ to feed live tabs, tab groups, screenshots, bookmarks, and local files into the AI. No more copy-paste gymnastics.
Save prompt recipes as /commands and generate one-sentence automation scripts. The Skills Marketplace lets you discover and share workflows.
Auto-grouped vertical tabs form focused workspaces. Research, shopping, and admin each get their own lane instead of one chaotic tab bar.
Antigravity strengths
Antigravity shines when the job is building software, not browsing the web.
A fully-featured IDE with an agent manager, artifacts, and deep codebase understanding — aimed at developers who want AI pair programming.
Antigravity agents can read, refactor, and generate code across entire repositories, not just answer questions about a single file.
The terminal-first CLI and Python SDK let power users build custom agents and automate software engineering tasks at scale.
Real-world scenarios
Pick the job that matches your day. The right tool is the one that completes more of the work for you.
Agent scans dozens of web sources, extracts data, and writes a structured brief in a parallel tab group.
Not designed for web browsing or research; focused on code repositories.

FAQ
No. Google Antigravity is an agentic development platform and IDE. It helps developers write and manage code with AI agents, but it does not browse the web or replace Chrome, Edge, or Tabbit.
