Balances top-tier accuracy with ease of use, perfect for customer-facing or internal knowledge projects.
No- Code Interface & Usability	Admin console and Atomic components let you get started with minimal code. The end-user search UI is polished, but full generative setup usually calls for developer involvement. Great for teams that already have technical resources or use Coveo today; more complex than a pure no-code tool.	Offers a wizard-style web dashboard so non-devs can upload content, brand the widget, and monitor performance. Supports drag-and-drop uploads, visual theme editing, and in-browser chatbot testing. User Experience Review Uses role-based access so business users and devs can collaborate smoothly.
