Last week at ZapConnect, Zapier announced a critical new feature that will allow users to take advantage of the flexibility and power of AI workflows, while balancing the inherent unpredictability that can come with generative AI.

Why Human in the Loop matters

AI unlocked a new class of automations: non-deterministic workflows that reason, write, and adapt. That’s powerful, but it also introduces variability. Traditional automations ran the same way every time. AI-powered ones might produce different outputs depending on inputs, prompts, or context. The upside is flexibility. The risk is unpredictability.

Human in the Loop (HITL) is how teams keep the benefits without flying blind. This new feature lets you easily add lightweight human approval and feedback at critical moments so you can scale AI responsibly, catch edge cases, and continuously improve your prompts and policies.

With Human in the Loop by Zapier, you can:

Reduce risk without losing speed. Gate high-impact actions with a quick review, then let the rest run hands-off.

Improve quality over time. Reviewers can correct tone, fill gaps, or refine structure—those edits become guidance for future runs.

Fit your governance model. Some steps need approval. Others just need a glance. HITL lets you choose where to intervene.

How Zapier’s Human in the Loop works

Zapier’s new Human in the Loop step lets you place a human checkpoint anywhere in your workflow. Here’s what it enables:

Notifications in the right channels. Route review requests to Slack, email, and more so approvers see them where they work.

Approve, decline, or edit before continuing. Reviewers can greenlight as-is, send back changes, or make quick edits that the Zap uses downstream.

Gather missing inputs. If the workflow needs a human-only detail—like a final headline, a budget cap, or a client-specific note—the approval step can collect it so the Zap proceeds with complete data.

Flexible placement. Add one checkpoint or many. Use it after AI-generated content, before external messages, or ahead of sensitive updates.

Where to use Human in the Loop

Human in the Loop steps are especially useful for any AI workflows where the chances or the costs of getting it wrong are high.

Some examples include:

Customer communications. Review AI-drafted replies before they go out.

Marketing and content. Approve or tweak AI-generated copy and assets.

Sales ops and revops. Confirm enrichment, scoring, or deal desk steps.

Compliance-sensitive tasks. Insert approvals where tone, accuracy, or policy matters most.

Put HITL to work in your team

Human in the Loop works best when it’s designed around your real-world edge cases, approvals, and policies. If you want a pragmatic plan for where to add checkpoints—and how to make them painless for reviewers—get in touch with work.flowers.
