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.
