What is Stack AI?
Stack AI is a no-code platform for building enterprise AI applications — document processing pipelines, internal AI tools, data extraction workflows, and AI assistants — through a visual drag-and-drop interface. Teams build pipelines that ingest PDFs or Word documents, extract specific information, classify content, generate summaries, and export structured data without coding. Enterprise features include SSO, audit logs, and role-based access control. Private deployment options available for data sovereignty. At $199/month for Starter, Stack AI targets enterprise teams with AI budget but without dedicated ML engineering resources.
How Stack AI works
Stack AI runs as llm application framework software built around text and document workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, with API access for teams that want to embed it into their own products.
