What is human in the loop?
Human in the loop is a design where an AI agent pauses at defined points and waits for a person to review, approve or correct its work before it continues.
The simple explanation.
Automation does not have to be all or nothing. Human in the loop means the agent does the heavy lifting while a person keeps the final say at the points that matter. The agent drafts the quotation, pulls the correct pricing, and formats it properly. Your sales lead glances at it and taps approve. The customer receives it seconds later. Most of the effort disappears, and the judgement call stays with the person who is accountable for it.
Where to place the checkpoint.
Put a human check where a mistake is expensive or hard to reverse: money leaving the business, a legal commitment, a discount above your normal band, a message to a major account. Let the agent run unattended where errors are cheap and easy to correct, such as answering opening hours or logging an enquiry. Reviewing everything defeats the purpose of automating. Reviewing nothing is how a small error becomes a large one. Most businesses land sensibly in between.
How the checkpoint changes over time.
The checkpoint is not permanent. A common pattern is to start with a person approving every action for the first few weeks, watch what the agent actually does, then relax the checks on the categories that have proven reliable while keeping them on the rest. The review log becomes your evidence. You are not guessing whether the agent can be trusted with a task, you are reading a record of how it handled that task a few hundred times.
The Voltade take
We assume a human in the loop on day one of every build, then narrow it as the evidence comes in. Approvals sit where your team already works, usually WhatsApp or Envoy CRM, so a review is a tap rather than another dashboard to log into. Trust in an agent should be earned by its record, not promised in a sales meeting.
