Privacy Notes
Publicly stated data-handling notes that matter when evaluating Stack AI.
Stack AI says customer data is not used to train its models, and says it has data processing addendums with third-party model providers so customer data is not used to improve those providers' products or models.
StackAI's security and privacy docs say organizations can define data-retention durations for stored data.
The LLM settings docs say memory data is encrypted end-to-end in the Stack AI database, and enterprise plans can self-host that data.

Product Snapshot
Stack AI is an enterprise AI agent platform for building and deploying workflow-based agents that work against company data and connected systems.
What You Can Do With It
- Build agents in a no-code workflow builder with logic, knowledge-base, and tool nodes.
- Connect enterprise sources such as SharePoint, Salesforce, Google Drive, Slack, Notion, and Google Sheets.
- Deploy workflows as chat assistants, forms, website chatbots, Slack apps, Microsoft Teams apps, batch jobs, or API endpoints.
- Apply enterprise controls such as SSO, audit logs, access controls, VPC deployment, and on-premise hosting.
Why It Stands Out
Stack AI is oriented toward governed enterprise deployment rather than lightweight consumer prompting. Its public docs and product pages emphasize workflow orchestration, security controls, and deployment flexibility across internal business systems.
Tradeoffs To Know
- The public pricing page currently shows only a free self-serve plan and a custom-priced enterprise tier.
- The current official materials surface broad provider and integration coverage, but not a single stable latest-model field suitable for structured inclusion here.
- Many of the strongest governance and deployment controls are positioned around enterprise deployments rather than the free plan.
