At StackAI, we spend every day working with enterprises to automate the most complex processes, from AML to FNOL. 

We heard the same thing over and over again: "We’re ready to automate this, but we're concerned about what happens if the AI gets it wrong."

That’s why we’re announcing Human-in-the-Loop (HITL): a powerful StackAI capability that lets agentic workflows pause and wait for human approval before resuming or taking critical actions.

How It Works

We all ask our managers for support or approval before proceeding with a sensitive operation. Now, agentic workflows follow the same pattern while running business-critical processes.

When a workflow reaches a decision point that requires human judgment, it pauses running, then sends a request for approval via Slack, Teams, email, or whatever channel your team already uses. Users can review, approve, reject, or give feedback. The workflow proceeds accordingly. 

This instantly makes agentic workflows more reliable and easier to embed in critical processes within regulated enterprises. 

A Real Example

One of our clients, a major global bank, was spending millions of dollars a year on AML compliance research, with each case taking 3-4 hours per analyst.

With StackAI, they built a workflow that handles the entire research and pre-screening process automatically: ingesting the government alert, calling sub-agents to search the internet and internal databases, cross-referencing the bank's SOPs from SharePoint, and writing a recommendation memo on whether or not to close the account. 

Here’s where HITL comes in. Before any action is taken, the workflow sends a request for approval to the compliance manager via Slack. The manager scans the memo, reviews the findings, and clicks approve or asks for more research. If approved, the agent logs into the bank’s compliance portal in a browser window, authenticates, and submits the request to close the account.

That’s hours of analyst work done in under two minutes, with HITL for full peace of mind. 

Humans and AI, Together

HITL unlocks dozens of use cases across every enterprise, from claim processing to work order forms, that require a human checkpoint before anything gets submitted. 

As AI starts to scale across the enterprise, we believe that human judgment will matter more than ever. That’s why we built it into StackAI. We’re proud to be the AI platform that enterprises choose for powerful, capable agentic workflows that keep humans in the loop at every step.
