What is Stack AI?

No-Code Enterprise AI Workflow Builder

Stack AI is a no-code platform for building and deploying AI-powered workflows and applications in enterprise environments. It enables teams to connect LLMs, vector databases, and external APIs into production AI applications through a visual drag-and-drop interface, without requiring machine learning expertise or deep programming knowledge.

Enterprise-Grade AI Workflows

Stack AI addresses the gap between AI experimentation and enterprise deployment. Its platform includes the security controls, access management, audit logging, and compliance features that enterprise organizations require. Teams can build document Q&A systems, AI assistants, data extraction pipelines, and content generation workflows and deploy them as internal tools or customer-facing applications.

  • Visual drag-and-drop AI workflow builder
  • LLM integration with OpenAI, Anthropic, and others
  • Vector database connectivity for RAG applications
  • Enterprise security with SSO and audit logs
  • One-click deployment as web apps or APIs
