What is StackAI?
StackAI is an enterprise platform for building AI agents and AI applications without writing code. Teams assemble workflows with a drag-and-drop editor, connect the agents to existing systems through more than 500 integrations, and choose the language model best suited to each task. The site positions it for IT teams that need to orchestrate, deploy and govern AI across the whole organization.
Agents built on StackAI can read, write and execute tasks inside the tools a company already uses. Deployment options include multi-tenant cloud, a virtual private cloud, or on-premise installation. Governance features mentioned on the site include feature controls, audit logs, access control, and human review points placed at critical decisions. The platform also offers a knowledge base feature for documents and web content, a REST API, and a Slack bot.
