Use Nanobrowser for browser tasks where the agent must operate inside the user’s own Chrome or Edge session, keep credentials local, and expose the navigation process for review. The operator installs the extension, configures provider keys, assigns models to the planner and navigator agents, then gives a concrete web task such as collecting information, completing a repetitive workflow, or inspecting a site. During the run, the operator can monitor browser state, review failures, adjust the task prompt, and rerun the job with narrower instructions. This is not a generic browser extension listing: the skill boundary is the repeatable operator workflow of configuring local browser agents, running a scoped task, watching the intermediate browser actions, and deciding whether the output is acceptable before using it downstream. Invoke it instead of using the product normally when the value is delegated, auditable web operation rather than manual browsing. Keep the task limited to sites and accounts the user is authorized to operate.
