Human-in-the-loop is not a checkbox. Design clear handoffs: when the AI drafts, when it recommends, when it acts, and when it escalates.
Define risk tiers
Low risk: automate fully (formatting, routing, data entry). Medium risk: suggest and approve (draft responses, classification, recommendations). High risk: draft only, human decides (compliance, financial, customer-facing).
The tier determines the UX, not the technology. Same model, different levels of human oversight.
Design review UX
Give reviewers context: sources, confidence cues, and one-click edits. Make it easier to accept than to ignore.
The biggest mistake in human-in-the-loop design is making the review process so painful that people either rubber-stamp everything or bypass the system entirely. The review interface is as important as the AI model.

Frequently asked questions
Will humans slow the system?
Only initially. Review loops are training data for better prompts, guardrails, and automation boundaries.
How do we prevent blind trust?
Show sources and enforce spot checks. Logging and sampling keep quality honest.
