HumanLayer is an infrastructure solution designed to integrate human oversight into AI agent workflows. It provides an API and SDK that allow autonomous AI agents — especially those executing tasks via tool-calling — to pause and request human input for decisions, feedback, or approvals. This “human-in-the-loop” design supports safer, more reliable automation by enabling intervention at key steps, particularly when an agent encounters ambiguity or risk.
HumanLayer is relevant for teams building AI systems that interact with real-world data or customer-facing processes, where full autonomy may not yet be viable or desirable. It also helps meet regulatory or operational standards requiring accountability and traceability. For businesses, it bridges the gap between AI scale and human judgment, offering a flexible, programmable layer of oversight that supports higher-confidence deployment of intelligent systems.
