   Smooth's core product is a task-delegation interface: users hand off a task description (e.g., navigate, extract, multi-step session workflow) to Smooth's built-in AI/browser agent, which executes autonomously and returns live_url and structured outputs (smooth-docs-1, smooth-docs-7, smooth-docs-8, smooth-docs-5). Community hands-on feedback corroborates it executing complex prompts well (smooth-comm-2, smooth-comm-1), though it is agent-facing (tool for other agents like Claude Code) as well as human-facing. Missing for 10: independent/reproducible benchmarks of task success (raised unanswered in smooth-comm-14) and clearer human-only assistant UX beyond API/CLI task calls.
