WidgetStack is a no-code platform that lets businesses create and deploy AI agents (chatbots) trained on their own content, automate workflows, and integrate with business tools—all in minutes.

⸻

🔑 Core Functions 1. AI Agent Creation • Build intelligent chatbots/agents without coding. • Train them on your documents, websites, or YouTube videos so they give accurate, business-specific answers. 2. Workflow Automation • Use a drag-and-drop builder to set up custom workflows. • Example: If a visitor asks about booking → the agent triggers Calendly. If they ask about payment → Stripe checkout launches. 3. Instant Deployment • Copy one embed code → paste it on your site → your AI agent is live in under a minute. 4. Integrations • Works with tools you already use: Stripe, Calendly, Zapier, Slack, Bland AI, etc. • Lets your AI agent book meetings, collect payments, send notifications, and more. 5. Analytics & Insights • Track conversations, usage, and customer interactions. • Identify what people ask most and optimize your agent or workflows accordingly.
