Last verified:
What is Stack AI?
Stack AI is an enterprise-grade no-code platform that enables teams to build, deploy, and govern AI agents without writing code. Using an intuitive drag-and-drop visual workflow builder, users can create powerful AI applications that automate complex business processes across finance, legal, HR, support, and other departments. The platform supports agentic workflows that transform time-consuming processes into working AI agents in minutes, with human-in-the-loop capabilities for oversight at critical decision points. Key features include 100+ enterprise integrations (Snowflake, Notion, SharePoint, ServiceNow, Confluence), RAG (Retrieval-Augmented Generation) with no-stress knowledge bases, LLM-agnostic deployment supporting multiple models like Anthropic Claude and GPT, multi-tenant/VPC/on-premise deployment options, and comprehensive security and governance with audit logs and access controls. The new Auto Agents system allows users to describe what they want in natural language and automatically generates complete multi-step AI agents with automatic prompt refinement and real-time testing. StackAI is designed for IT teams, enterprise architecture teams, and organizations with regulated or complex operations including healthcare, finance, legal, and government. It serves over 35,000 users and 300+ paying enterprise customers, backed by Y Combinator and Gradient Ventures. The platform is built by MIT PhDs and provides enterprise certifications including SOC 2 Type II, HIPAA, GDPR, and ISO 27001 compliance.

Frequently asked questions about Stack AI
What does StackAI do?
StackAI is an enterprise platform for building, deploying, and governing AI agents. It enables teams to design and deploy powerful AI workflows without writing code using a visual drag-and-drop builder. Users can connect knowledge bases, tools, and business systems, then deploy agents to chat interfaces, forms, APIs, and internal teams. The platform operates safely with governance, access controls, and observability features.
What problem does StackAI solve?
StackAI solves the gap between building AI demo agents and deploying enterprise-ready production systems. It automates manual, repetitive, and expensive business processes across finance, legal, HR, and support departments. The platform enables organizations to transition from AI experimentation to execution with governed workflows, RAG capabilities, and expansive integrations while maintaining enterprise security and compliance.
Is StackAI no-code or low-code?
StackAI is a no-code platform that empowers teams to design and deploy AI workflows without writing a single line of code. It uses a drag-and-drop visual builder where users select pre-built templates, add knowledge base nodes, plug in tools and integrations, customize, deploy, and export for others to use. The low-code approach democratizes AI development across organizations.
What enterprise certifications does StackAI have?
StackAI is certified with SOC 2 Type II (verified security practices for enterprise-grade data protection), HIPAA (secure handling of sensitive health information), GDPR (advanced privacy standards for personal data protection in Europe), and ISO 27001 (global information security management excellence). These certifications protect sensitive data across any industry or use case.
What integrations does StackAI support?
StackAI offers 100+ enterprise integrations including Snowflake, Notion, SharePoint, ServiceNow, Confluence, and many more. AI agents built on StackAI can read, write, and execute tasks within existing enterprise systems. Users can drag integrations into the workflow canvas, select which documents or data to access, and connect them to question blocks and LLM blocks.
What is StackAI Auto Agents?
Auto Agents is a new system within StackAI that allows users to instantly design, test, and iterate over custom AI agents using natural language. Users describe what they want to build, and the platform automatically generates a complete multi-step AI agent including workflow, tools, and logic. Features include automatic prompt refinement with a single click, real-time testing and iteration, interactive follow-ups through chat, and enterprise-grade security by default.
Can StackAI deploy on-premise or in VPC?
Yes, StackAI supports multi-tenant, VPC (Virtual Private Cloud), and on-premise deployment options. Enterprise plans include dedicated infrastructure, on-prem deployment, and VPC deployment with access control and Single Sign-On (SSO). This flexibility allows enterprises to maintain control over their data and deployment environment based on security requirements.
What models does StackAI support?
StackAI is LLM-agnostic, allowing users to deploy the best-performing model for every specific task. The platform supports multiple models including Anthropic Claude (Sonnet 4.5), GPT-4.1, and others. Users can select their preferred model in the workflow builder and customize instructions for how the assistant should behave.
How does StackAI handle security and governance?
StackAI provides enterprise-grade security with feature controls, audit logs, and comprehensive access controls. The platform includes Agentic Development Life Cycle (SDLC for the AI era) to keep enterprises in control. Governance features include observability, role-based access, and the ability to integrate human oversight into automated decision points for total process precision.
