The Navigator Browser Extension is a lightweight Chrome extension that wraps around the Navigator API to automate browser tasks. It’s a convenient way to try out both Navigator n1.5 and Navigator n1 on real pages without writing any code — Navigator n1.5 is the default and recommended model. Simply describe what you want to do, and the agent will execute it step-by-step—clicking, typing, scrolling, and navigating autonomously.Documentation Index
