About this listing

Product and access model reviewed from current official sources; workflow and example are editorial suggestions, not a hands-on test.

Official source

Build enterprise AI workflows with model and data connections, human review, deployment controls, and reusable interfaces.

Best suited to

StackAI suits technical and operations teams assembling an AI workflow around internal sources and permitted actions.

Meet Stack AI

StackAI suits technical and operations teams assembling an AI workflow around internal sources and permitted actions. Its current platform remains a distinct workflow product following its announced acquisition by Asana. Start with a read-only knowledge task and a clear review point. A visual flow still needs decisions about data access, model behavior and what happens when the source is incomplete.

A practical workflow

  1. Choose a small approved knowledge source.
  2. Connect a model and define the workflow's scope.
  3. Add a review step before consequential actions.
  4. Test missing answers and inspect execution behavior.

Illustrative input

This example describes a task, not a tested output. Adjust the source material and settings to your own situation.

Build a handbook assistant that cites approved content and escalates any question the handbook cannot answer.

Result check: Check retrieved passages, permissions and whether the workflow stops at the required review point.

Access and alternatives

The public Free plan lists recurring monthly runs with limited projects and seats. Enterprise access has custom run capacity, integrations, infrastructure and governance terms. Confirm current acquisition-related account terms and feature eligibility; a free prototype plan is not the same as a production deployment agreement.

Choose another workflow when its emphasis fits better: Dify for another application-and-workflow platform; Flowise for a more self-hosted visual agent approach.
