Human-in-the-Loop (HITL)

Term explanation

Definition and meaning

Human-in-the-loop (HITL) refers to a design pattern in AI systems where a human is involved at specific decision points to review, approve, or correct the AI's actions before they are executed. Rather than running fully autonomously, the system pauses at predefined checkpoints and waits for human confirmation — particularly for high-stakes or irreversible actions. HITL works alongside AI guardrails as a key governance principle in enterprise Agentic AI, balancing the efficiency of automation with accountability and human judgment.

LIZ AI supports configurable human-in-the-loop workflows: teams can define exactly where they want to review and approve AI-generated presentation content before it is distributed — keeping full control without giving up the benefits of automation.

In remote and hybrid workplaces, replicating the natural flow of informal communication has become an important design challenge.
