Agentic AI Browsers
Agentic AI browsers let LLMs interpret intent, navigate sites, and finish multi-step work—without you clicking every step. Tabbit runs those agents in isolated tab groups while you keep browsing.

What are agentic AI browsers?
Not every “AI browser” is agentic. True agentic AI browsers combine three capabilities that separate them from sidebar chat or search overlays.
LLM-driven planning
A large language model reads page structure, adapts to layout changes, and replans when a site throws a curveball.
Multi-step workflows
Research across tabs, compare products, aggregate data, or run approvals—work that spans minutes and multiple sites.
