Human-in-the-Loop AI Cost Model
AI rarely replaces people outright — it drafts, and a human reviews. Model the true cost of that blend against doing the work fully manually, including the cost of errors.
Quick answer
Enter your monthly volume, the share AI can handle, minutes for AI review versus manual handling, hourly cost and error rates. The model returns labour cost, error cost, total cost and the saving versus an all-manual process.

Frequently asked questions
What is human-in-the-loop AI?
A workflow where AI drafts or triages the work and a person reviews and approves it, rather than AI acting unsupervised. It trades some speed for control and accountability.
Why include error cost?
A cheaper process that makes more mistakes can cost more overall. Modelling error rate and cost-per-error shows the true comparison, not just labour hours.
When does human-in-the-loop beat full automation?
Whenever a mistake is expensive or hard to reverse — compliance, money-touching steps, customer-facing decisions. The review time is the price of that safety.
