The Stack / Automation
Stack AI
Yes for companies that need internal AI tools with governance — Stack AI's visual builder plus enterprise controls fits operations that can't just point staff at a chatbot. Solo operators: n8n's agent nodes cover most of this for a fraction of the price.
The job in the stack
The internal-AI-apps seat: drag-and-drop LLM workflows — document processing, internal assistants, approval chains — deployed to your team.
Pricing
| Plan | Price | Notes |
|---|---|---|
| Free | $0 | Sandbox tier for building |
| Starter | ~$199/mo | Team deployment — pending fresh verification |
| Enterprise | custom | SSO, VPC, compliance controls |

The honest read
What works
- +Internal AI apps with real interfaces, not just chat windows
- +Enterprise posture: access control, data governance, on-prem options
- +Multi-model: route steps to whichever LLM fits
What breaks
- −Priced for teams — steep for solo operators
- −Overlaps n8n for workflow automation; justify the second seat
- −Complex apps still need someone who thinks in data flows
Use it for
- →Mid-size companies deploying internal AI assistants with controls
- →Document-heavy operations: intake, extraction, approval flows
- →Teams that need AI apps non-technical staff can actually use
Skip it if
- ×You're solo — n8n plus Claude covers this cheaper
- ×You just need one chatbot on your site — that's CustomGPT's job
Questions operators ask
?Stack AI or n8n?
