StackAI

Low-code platform to build AI workflows

Overview

Stack AI builds an enterprise-ready, no-code platform for creating and deploying AI agents and workflow automations. It uses a visual drag-and-drop interface to connect data sources and large language models with business systems like SharePoint, Snowflake, Salesforce, Google Drive, and Notion, enabling knowledge-based assistants, contract analysis, RFP responses, and data extraction. The platform lets teams assemble AI-powered workflows that fetch data, run models, and deploy applications without heavy coding, speeding internal tooling. Its differentiators are enterprise-focused deployment options (including on-premise), compliance (SOC 2, GDPR, HIPAA), and tiered pricing, aimed at reducing deployment time and improving model accuracy across back-office processes.
